4220 Flow Meter Section 1 Introduction Battery capacity is expressed in ampere-hours. The battery manufacturer provides this information for each battery. This value is the product of a load current times an arbitrary time period, ten hours for nickel-cadmium batteries, and twenty hours for lead-acid types. The terminal voltage of the battery at the end of this time period is the discharged cell voltage, 10 volts for nickel-cadmium and 10.5 volts for lead-acid types.
4220 Flow Meter Section 1 Introduction nickel-cadmium batteries show fairly rapid rates of self-discharge. A battery that is fully charged and then placed in storage will lose some capacity each day. In a week, this could easily be 5% or more. When using lead-acid batteries, you must be careful to avoid complete discharge, as this may cause cell reversal, which will ruin the battery.

The power supply should have at least 3 Amperes output, preferably more, and capable of overcurrent surges.
4220 Flow Meter Section 1 Introduction 1-14
4220 Flow Meter Section 2 Programming 2.1 Getting Started You must program the 4220 Flow Meter to accurately monitor a flow stream. You must also install the submerged probe level sensor. The 4220 will usually also need a primary measuring device, a structure placed across a stream that regulates flow. This section describes programming the flow meter with the aid of the keypad and display. There are nine program steps that control all aspects of the flow meter's operation.
4220 Flow Meter Section 2 Programming condition means that the flow meter will enable the sampler only when a certain condition or set of conditions, sensed by the flow meter, are met.) Total Flow Flow Rate Current Level Date (or pH/D.O.) Time (temperature) Following is a typical programming display on the flow meter. One of the items in the second line will be flashing. The item flashing is the selection currently held in memory.
4220 Flow Meter Section 2 Programming Print Program - Pressing this key will make the flow meter print out a complete list of the current program choices retained in memory. Print Report - One function of the flow meter is to print reports of all recorded activity at regular intervals. The contents of these reports are defined in step 1. If you set up the report generator, you can have a report printed anytime by pressing this key.
4220 Flow Meter Section 2 Programming If you want a different choice from the one that is flashing, you can move across the display by using the left and right arrow keys. Each time you press the right arrow key, the flashing selection will move one position to the right. This will continue until the flashing cursor is over the last display. You may notice an arrow pointing to the edge of the display. This indicates additional choices are available beyond what you can see.
4220 Flow Meter Section 2 Programming 2.3 Description of Program Steps The Program Steps for the 4220 are: 1. Operating Mode 2. Flow Conversion 3. Adjust Level/Parameters 4. Reset Totalizer 5. Sampler Pacing 6. Sampler Enable 7. Alarm Dialout 8. Printer 9. Reports/History Note 2.3.
4220 Flow Meter Section 2 Programming 2.3.2 Step 2, Flow Conversion Type Step 2, Flow Conversion Type, determines how the flow meter calculates flow rate and total flow. For the 4220 Flow Meter, flow rate is calculated by knowing the measured level and (usually) the characteristics of a structure called a primary measuring device. A primary measuring device is a structure placed across a flow stream through which the entire stream must flow.
4220 Flow Meter Section 2 Programming An Equation is used when you have a non-standard primary device, or want to use different values from those programmed into the look-up tables of the flow meter. Equation uses the standard flow equation: Q = k1HP1+ k2HP2 Where Q equals flow rate; k1 and k2 are constants; H is level (or head), and P1 and P2 are the powers to which the two H terms are raised. (Your equation may not have the second term, in which case you would enter 0 for the second constant, k2.
4220 Flow Meter Section 2 Programming The port is not dedicated to a particular sensor, except through programming. You can change the sensor. For example, you can change from a pH probe to a D.O. sensor if you change the programming. Selection of one parameter will keep the other from showing up on the menus. Note, however, that it is possible to measure several different stream conditions including pH and D.O. at the same time with the YSI 600 Sonde.
4220 Flow Meter Section 2 Programming control. There are several possible options—DISABLE, CONDITIONAL, VOLUME, and FLOWLINK. DISABLE will keep the sampler from receiving a flow pulse from the flow meter. VOLUME allows the flow meter to signal the sampler whenever a specific flow volume has passed by. Flowlink (this option will only appear if you are using Flowlink software) allows the sampler to be signalled from the flow meter as a result of conditions determined by Flowlink.
4220 Flow Meter Section 2 Programming combination of these conditions. The YSI 600 Sonde provides several measurements at the same time. You must have the appropriate sensors for rainfall, temperature, D. O., pH and the YSI outputs. Note 2.3.7 Step 7 - Alarm Dialout Mode You must have the optional modem to make use of this program step. The menus will not even appear unless the flow meter has a modem installed.
4220 Flow Meter Section 2 Programming Typically included are such items as maximum and minimum flow rates, the time they were reached, sample records, etc. The flow meter lets you create two separate reports, and lets you define what appears on them to a great extent. Note that the contents of the reports are defined in Setup in step 1. Step 9 merely lets you turn them off and on and set the timing. You can define the start time, the interval between reports and other aspects of the report.

4220 Flow Meter Section 2 Programming YSI 600 READING INTERVAL refers to the YSI 600 Sonde. The flow meter can measure several different aspects of the stream at the same time, including pH, D.O., temperature, plus conductivity. If you select LEVEL READING INTERVAL, the following will appear: LEVEL READING INTERVAL • CONTINUOUS • • 15 SEC • • 30 SEC • • 1 MIN • • 2 MIN • • 5 MIN • The LEVEL READING INTERVAL option is a way to conserve power in battery-powered installations.
20 Flow Meter Section 2 Programming Return to the Setup menu if the unit has not already done so. This time select ENABLE/ALARM HYSTERESIS from the menu. Press Enter. The following will appear: LEVEL ENABLE/ALARM HYSTERESIS X.XXX FT (or other units of measure) The HYSTERESIS menu lets you set the range over which the level (or other condition) can vary before the flow meter responds to the change.
4220 Flow Meter Section 2 Programming The following will appear if you are measuring D. O: DO ENABLE/ALARM HYSTERESIS X.XXX PPM (or mg/l depending on units selected in Program.) A set of menus similar to those shown above for pH, D.O., and temperature will then appear for the YSI 600 Sonde, if you have selected it. You can set hysteresis for YSI-pH, YSI-D.O., YSI-Conductivity, and YSI-temperature, if these parameters have been turned on in previous program selections. 2.4.
4220 Flow Meter Section 2 Programming or two current loops supplied. If you use both the external converter and the internal board, you can have a total of four current loops controlled by the same flow meter. The internal current loops are brought out to a 6-pin M/S connector in the slot where the Modem connector is usually mounted. To activate the internal analog output(s), return to the main screen and press 4, 2, 0.
4220 Flow Meter Section 2 Programming occurs, return to the 4 - 2 - 0 option, and at the prompt enter 0 for the number of outputs activated. This will restore the external 4-20 mA converter capability. MANUAL CONTROL will appear if you continue moving to the right. “RANGE” will appear with the ANALOG OUTPUT menu if the optional internal 4-20 mA converter is present in the flow meter.
4220 Flow Meter Section 2 Programming Programming for the conditions and values that determine the operation of the 4-20 mA loop (or loops) is done in Programming Step 2, following the entry of FLOW RATE AT MAXIMUM HEAD. Note The information in the following section is provided for those who can write their own software programs to process the data transmitted from the Serial Output port. Special cables may be required. Contact Teledyne Isco technical support for more information.

If you select FLOW RATE: FLOW RATE • GREATER THAN • • LESS THAN • • RATE OF CHANGE • You would select one of these options, and then enter a value, as for LEVEL, previously. The rest of the menus will appear the same as they did for LEVEL and FLOW RATE. D. O.
4220 Flow Meter Section 2 Programming Note You must have the optional internal modem installed and connected to a telephone network to make use of this feature. This menu will not even appear if you do not have a modem. The flow meter will automatically advance to the next step. More information about the modem can be found in Section 5.
4220 Flow Meter Section 2 Programming least one of the options will be available to you. As mentioned for other program steps, some of these menu options may not appear depending on the flow meter you have and choices you made earlier in the program. D. O., pH, TEMPERATURE, and RAINFALL all require activation in step 1 and connection of the appropriate sensor to the flow meter. D. O. and pH will never appear together, as only one can be used at a time.
4220 Flow Meter Section 2 Programming arranged in decreasing priority. NUM 1 carries the highest priority, followed by NUM 2 and so on. After you have entered the numbers, the flow meter will request: DELAY BETWEEN DIALOUTS XX MINUTES This is the time delay between calling the first number and calling the second, etc. This option gives you time to respond to an alarm before the flow meter dials the next number. Select a value between 1 and 99 minutes.
4220 Flow Meter Section 2 Programming (TEMPERATURE), (YSI pH), (YSI D.O.), (YSI CONDUCTIVITY), and (YSI TEMP) can also appear. Remember that menus in parentheses may not appear due to previous program selections. Either pH or D. O. may appear, but not both.

4220 Flow Meter Section 3 Installation 3.1 Introduction 3.1.1 Preparation for Use This section of the manual contains detailed information on the installation of the 4220 Flow Meter. Included are sections on the power sources, mounting methods, interconnection wiring, installation of the submerged probe and setup procedure for the unit. The flow meter is shipped with a roll of paper installed and a standard program in the system memory, also called the default program.
4220 Flow Meter Section 3 Installation cartridge should be colored blue. If it is violet or pinkish, you need to regenerate it. You will need to remove the particles from the cartridge for regeneration; you cannot regenerate the cartridge like the case desiccant canister. The cartridge is plastic and will melt. See Section 6 for details on regenerating the desiccant cartridge. CAUTION Do not operate the flow meter with the door open or the desiccators saturated.
4220 Flow Meter Section 3 Installation 3.1.4 Opening the Case 3.2 Connection to a Power Source To access the flow meter controls and internal plotter, you must open the case. Unlatch the two catches on the right side of the case and pull open the lid. You will need to open the case whenever you change the plotter chart or change the programming with the keypad. You can read the display through the window, so periodic readings may be taken without opening the case.
4220 Flow Meter Section 3 Installation Note Do not attempt to run a sampler from a power source installed on a flow meter. While a flow meter will operate satisfactorily powered from a sampler, the reverse is not true. The sampler's pump draws heavy current, particularly on startup. The flow meter-to-sampler connect cable cannot carry such currents. If you are using a single power source for a flow meter-sampler combination, always install the power supply on the sampler. 3.2.
4220 Flow Meter Section 3 Installation 3.2.5 Isco Lead-Acid Battery Teledyne Isco also offers a 6.5 ampere-hour 12-volt rechargeable lead-acid battery to power the flow meter. This battery is similar in size to the nickel-cadmium battery, except somewhat larger, reflecting its 50% greater capacity. For those familiar with nickel-cadmium batteries, operation and maintenance of these batteries differs somewhat.
4220 Flow Meter Section 3 Installation Figure 3-2 Power Pack Installed on a Flow Meter They are both capable of powering the flow meter. The Battery-Backed Power Pack provides 12 VDC at 5 Amperes, and is backed up by a 1.2 Ampere- hour nickel-cadmium battery. This is built in a package the same size as the standard power supply, and is intended for use where short-term power interruptions are frequent but unacceptable for flow meter operation.
4220 Flow Meter Section 3 Installation Teledyne Isco offers a special optional connect cable to power the flow meter from a separate battery. Mount the battery securely, in an upright position, so it will not inadvertently tip over, or be at risk of having its cable pulled off. CAUTION Be sure of proper polarity before attaching clips to the battery. Never attach the flow meter to a source of unknown polarity or voltage. If in doubt, check with a reliable DC voltmeter.
4220 Flow Meter Section 3 Installation 3.3.2 Location of the Flow Meter Because the flow meter uses a submerged probe for level measurement, you do not have to install it directly above the primary measuring device, or even particularly close to the flow stream. You can install the flow meter in a convenient, protected location and route the submerged probe cable to the place where the level sensor is mounted.
4220 Flow Meter Section 3 Installation submerged probe extension cables.) Do not try to patch extension cords. If you need to operate at greater lengths, use the Quick-Disconnect Box. To use the Quick-Disconnect box, you will need a cable of the correct length with an M/S connector to plug into the flow meter. Teledyne Isco will build the cable with the proper connector on one end and stripped wire ends on the other as a special order.
4220 Flow Meter Section 3 Installation mersion when the stream is high, you should protect the desiccator and the reference port by venting them at a point the water cannot possibly reach. Remember that water or other blockage inside the submerged probe's vent tube will ruin the submerged probe. It is even more important to protect the Quick-Disconnect Box this way than the flow meter, because of the likelihood that the submerged probe will be directly connected to the Quick Disconnect Box.
4220 Flow Meter Section 3 Installation WARNING The 4220 Flow Meter has not been approved for use in “hazardous locations” as such locations are defined by the National Electrical Code. Before any flow meter is installed, the proper safety precautions must be taken. The discussions of safety procedures are only general guidelines. Each situation in which you install a flow meter varies. You must take into account the individual circumstances you are in.
4220 Flow Meter Section 3 Installation 3-12
4220 Flow Meter Section 4 Submerged Probe Installation The following sections describe installation of the submerged probe. The first section presents general mounting considerations common to all submerged probe mounting techniques. The following sections describe probe installation using the two systems available for mounting the submerged probe in pipes or round-bottomed flow streams. For pipes up to 15 inches (38.1 cm) in diameter, spring stainless steel self-expanding mounting rings are available.
4220 Flow Meter Section 4 Submerged Probe Installation The probe has several ports through which liquid enters the body to contact the pressure transducer. The only way for the probe to malfunction is for all the ports to be completely blocked. Most substances likely to cover the probe are somewhat porous, which still allows the hydrostatic pressure of the flow stream over the probe to reach the transducer. 4.1.
4220 Flow Meter Section 4 Submerged Probe Installation Slanted Nose Section Slanted Nose Section – Under certain conditions - low flow rates in debris-laden small sewers, for example - the submerged probe may catch and retain the debris, obstructing the flow stream and causing erroneous level readings. To avoid this problem, use the slanted nose section. This nose section has a slanted leading edge that tends to shed debris more readily than the standard nose section.
4220 Flow Meter Section 4 Submerged Probe Installation Compress ring into gap to install in pipe, then... ...outward force of ring against pipe wall holds ring in place inside pipe. Figure 4-1 Sensor Installed on a Spring Ring Attaching the Sensor to the Ring Attach the probe to the ring either by using two 4-40 x 3/16" countersink screws or by snapping the optional probe carrier to the ring. This second method of attaching the sensor allows for easy removal in case service is needed later.
4220 Flow Meter Section 4 Submerged Probe Installation Figure 4-2 Spring Ring Preparation F lo w Figure 4-3 Mounting Ring in a Round Pipe CAUTION Make sure the sensor cable is securely fastened along the back (downstream) edge of the ring. Otherwise, the sensor may provide inaccurate level readings under conditions of high velocity. Do not overtighten the plastic cable ties; they should be tightened just enough to secure the cable in place, without greatly indenting the cable.
4220 Flow Meter Section 4 Submerged Probe Installation The spring ring may need anchoring. Under conditions of high velocity (greater than 5 feet per second or 1.5 meters per second), the ring may not have sufficient outward spring force to maintain a tight fit inside the pipe. The ring may start to lift off the bottom of the pipe in a waving fashion, or may even be carried downstream.
4220 Flow Meter Section 4 Submerged Probe Installation Assembling the Rings The scissors mechanism will work best if the respective assembly is installed to allow the scissors to expand approximately in the middle of the adjustment. Do not overtighten the mechanism. It is designed to flex somewhat to provide a positive lock, once moderately tightened. When assembling the ring sections, make sure the tongue sections are correctly inserted into the slotted sections.

4220 Flow Meter Section 4 Submerged Probe Installation To prevent debris from catching on the cable, it is important to attach the cable to the mounting ring so it offers as little resistance to the flow as possible. Attach the sensor cable to the downstream edge of the ring, using the self-locking plastic ties supplied with the ring. Place the ties through the holes in the edge of the mounting ring and then lock them around the cable.
4220 Flow Meter Section 4 Submerged Probe Installation A variety of threaded fasteners should be available in various overall and thread lengths; a minimum thread length of 1/4 in. (0.63 cm) is recommended. Be sure to follow the manufacturer's instructions carefully, and observe all safety precautions. 4.3.5 Completing the Probe Installation The probe installation is finished by coiling any excess sensor cable and securing it using cable clamps or other means.

4220 Flow Meter Section 5 Options and Accessories The Parameter Modules themselves plug into the Parameter Probe connector on the flow meter. CAUTION The pH and D.O. probes require continuous submersion after installation, or they will lose sensitivity. Prolonged dehydration of the sensor bulb may damage or even ruin the pH probe. 5.8 The Temperature Probe The temperature probe is the simplest of the three, consisting of a thermistor inside a metal housing.
4220 Flow Meter Section 5 Options and Accessories The dissociation constant is a number indicating the degree of ionic dissociation for a substance after it is dissolved in water. Dissociation constants vary widely for substances depending on the nature of the substance’s chemical bonds. Ionic salts tend to have higher constants. Each number on the pH scale between 7 and 0 equals a tenfold increase in H + ion. Each number between 7 and 14 equals a tenfold decrease of H+ ion.
4220 Flow Meter Section 5 Options and Accessories pH measurement is affected significantly by temperature, like any other chemical reaction. Consequently, temperature compensation is provided. in the flow meter. The Isco pH probe has a built-in temperature sensor that is exposed for faster response.

4220 Flow Meter Section 6 Maintenance and Service 6.1 Routine Maintenance and Minor Service The following sections provide routine maintenance and servicing instructions. Included are sections on cleaning the flow meter, reactivating the desiccators, maintaining the bubble line, servicing the internal printer, elementary troubleshooting and servicing CMOS circuitry. Teledyne Isco recommends that you become familiar with the maintenance procedures presented here.
4220 Flow Meter Section 6 Maintenance and Service 6.2 Reactivation of the Desiccators The 4220 has a reusable desiccant canister held by a steel clamp on the inside of the case lid. There is also a tubular desiccant cartridge on the top of the case next to the connectors. The canister contains silica gel that adsorbs moisture trapped inside the flow meter's case when it is closed. This keeps the inside of the case completely dry during shipment, storage and use.
4220 Flow Meter Section 6 Maintenance and Service 6.2.2 Regenerating the External Desiccant Cartridge Teledyne Isco uses two types of silica gel: • One looks like small beads or pellets that are blue-black when dry, pale pink to transparent when saturated. • The other looks like coarse sand, yellow when dry, dark green when saturated. Regenerate desiccant by heating at 212° - 350° (100° - 175°C). MSDS (Material Safety Data Sheets) for silica gel chemicals are provided at the back of this manual.
4220 Flow Meter Section 6 Maintenance and Service Note Regeneration of the desiccators is extremely important. Saturated desiccators let the flow meter draw moisture inside, exposing both mechanical and electronic components to water and/or chemical contamination. The air in many installations contains fumes that will form acids in the presence of moisture. These acids may corrode electrical components, particularly connectors and circuit boards.
4220 Flow Meter Section 6 Maintenance and Service 6.3.2 Cleaning the Submerged Probe Without Disassembly Occasionally, organic materials may become jammed inside the submerged probe's housing. If this material swells as it becomes saturated with water, it will exert pressure on the stainless diaphragm placed over the transducer.
4220 Flow Meter Section 6 Maintenance and Service Again, any deformation of the stainless steel diaphragm will permanently disable the submerged probe. If you must remove the nose of the probe, do it very carefully. A small warning disk is located in front of the transducer. Do not remove the warning disk. After cleaning, reinstall the nose section and tighten the screws. The mounting hole must be aligned with the grounding point. Figure 6-3 Alignment of Grounding Point 6.3.

4220 Flow Meter Section 6 Maintenance and Service 7. Locate the three small pins on each spool of the ink ribbon and turn the spools so the pins face the gears on the two ribbon shafts. 8. Replace the two spools on their respective shafts, pushing the detector levers out of the way so the spools will easily re-engage their gears. 9. Gently rotate each spool to tighten the ink ribbon. Reinstall the paper take-up roll if necessary. 6.4.
4220 Flow Meter Section 6 Maintenance and Service Note If you disassemble the flow meter for servicing, you will also remove the aluminum chassis covers to access the circuitry. Always replace these covers when repairs have been completed. The covers protect the circuit boards and also reduce signal emissions that could interfere with the operation of nearby electronic equipment. For the same reason, do not remove any of the ferrite beads or alter the wiring harnesses inside the cabinet in any way.

4220 Flow Meter Section 6 Maintenance and Service 6.6.2 Inspection Protocol When attempting to isolate problems within the unit, you should assume that the CPU and memory are working properly until attempts to find problems in the peripheral circuitry have been exhausted. This is for two reasons: • The likelihood of failure is far greater on transistor drive circuits (heavier currents are handled here), than on the CPU or memory.
4220 Flow Meter Section 6 Maintenance and Service 9. Check the input signals to the unit and see that they are correct. This may require the use of an oscilloscope. You may need to consult Customer Service for the proper appearance of wave forms. 10. Check to see that the crystal oscillator is operating and at the proper frequency. 11. Check the reset circuitry to see that it is working properly. 6.
4220 Flow Meter Section 6 Maintenance and Service circuitry. Simply being connected to the rest of the circuitry provides some protection. Most of the circuitry is well-protected from damage caused by static discharge when the unit is powered up. However, an IC should never be replaced when the unit is turned on. • Individual CMOS semiconductors and built-up printed circuit boards should always be transported in conductive packaging. Foil is satisfactory; metallized plastic bags work well.

The following sections provide safety procedures for working in and around manholes and sewers. the first section offers general safety advice. The second section deals with the special problem of hazardous gases found in sewers.
4220 Flow Meter Appendix D General Safety Procedures “Lifting Injuries. Unless proper tools are used to remove manhole covers, back injuries or injuries to hands or feet may result. “2. Planning. Advance planning should include arrangements for test equipment, tools, ventilating equipment, protective clothing, traffic warning devices, ladders, safety harness, and adequate number of personnel. Hasty actions may result in serious injuries. Time spent in the manhole should be kept to a minimum. “3.
4220 Flow Meter Appendix D General Safety Procedures the manhole opening. To avoid a serious injury, a person should not be lifted out of a manhole by his arm unless it is a dire emergency. “When more than one person must enter a manhole, the first person should reach the bottom and step off the ladder before the next one starts down. When two men climb at the same time, the upper one can cause the lower one to fall by slipping or stepping on his fingers. “5. Traffic Protection.

4220 Flow Meter Appendix D General Safety Procedures “It seems unlikely that anyone has ever died in a sewer from suffocation, that is, a lack of oxygen. Deaths have often been attributed to ‘asphyxiation.’ This is a word which, according to the dictionary, is used to mean death from an atmosphere that does not support life. The word has sometimes been misinterpreted as meaning suffocation, which is only one kind of asphyxiation. “In nearly all cases of death in sewers, the real killer is hydrogen sulfide.
4220 Flow Meter Appendix D General Safety Procedures number of harmful vapors. They, too, are sensed by smell and explosimeter tests if they get into the public sewer. Such occurrences are rare. “The attempt to instill a sense of urgency about real hazards is diluted if a man is told to give attention to a long list of things that in fact are irrelevant. “Be very careful to avoid high H2S concentrations, flammable atmospheres, and hazards of physical injuries.
