PART 1 - INTRODUCTION General The MagProbe is a point-velocity measuring device used primarily for measuring electrically conductive liquids, such as water and water-based liquids, in closed piping systems. The unit operates utilizing Faraday’s principle of magnetic conduction, whereby a moving conductor (the liquid) has a voltage imposed on it that is directly proportional to two variables—the strength of a local magnetic field and the velocity of the moving conductor.
PART 1 - INTRODUCTION The MFX MagProbe flow meter can be successfully applied on a wide range of metering applications. The simple to program transmitter allows the standard product to be used on pipe sizes ranging from 4 - 120 inch (100 - 3048 mm) pipe. A variety of liquid applications can be accommodated: potable water, chemicals, raw sewage, reclaimed water, cooling water, river water, plant effluent, etc.
PART 1 - INTRODUCTION User Safety The MFX employs modular construction and provides electrical safety for the operator. The display face contains voltages no greater than 10 Vdc. The display face swings open to allow access to user connections. As a general precaution, always disconnect electrical power before opening the instrument enclosure. Data Integrity Non-volatile memory retains all user-entered configuration values in memory even if power is lost or turned off.

PART 1 - TRANSMITTER INSTALLATION Transmitter Installation After unpacking, it is recommended to save the shipping carton and packing materials in case the instrument is stored or re-shipped. Inspect the equipment and carton for damage. If there is evidence of shipping damage, notify the carrier immediately. The enclosure should be mounted in an area that is convenient for servicing, calibration or for observation of the LCD readout. 1.
PART 1 - TRANSMITTER INSTALLATION Figure 1.5 - MFX Transmitter Installation Dimensions Rev. 01/11 -1.
PART 1 - TRANSMITTER INSTALLATION MagProbe Connections To access terminal strips for electronic connectors, loosen the two screws in the enclosure door and open the door. 1. Guide the MagProbe terminations through the transmitter conduit hole located in the bottom-center of the enclosure. Secure the MagProbe conduit with the supplied conduit nut if flexible conduit was ordered with the transducer.
PART 1 - TRANSMITTER INSTALLATION CAUTION: Any other wiring method may be unsafe or cause improper operation of the instrument. Do not run line power with other signal wires within the same wiring tray or conduit. NOTE: This instrument requires clean electrical line power. Do not operate this unit on circuits with noisy components (i.e. fluorescent lights, relays, compressors, variable frequency drives, etc.
PART 1 - TRANSMITTER INSTALLATION AC POWER CONNECTIONS 1. Verify that the jumpers at JP3 are properly oriented for the power supply. Verify that the jumpers at JP1 and JP2 are not present. 2. Connect L1, L2 and earth to the terminals referenced in Figure 1.7 on page 1.13. Phase and neutral connections to L1 and L2 are not polarized. Do not operate without an earth ground connection. 3. See Figure 1.8 for AC connection schematic. Wire gauges up to 14 AWG can be accommodated in the MFX terminal blocks.
PART 1 - TRANSMITTER INSTALLATION DC Power Supply DC POWER CONNECTIONS The MFX may be operated from a 9-28 Vdc source, as long as the source is capable of supplying a minimum of 3 Watts. 1. Verify that the jumpers are properly placed. See the wiring diagram located on the inside door of the MFX enclosure or see Figure 1.7 on page 1.13. The jumpers at JP3 should not be present and the jumpers at JP1 and JP2 will be in place.
PART 1 - ISO-MOD General The MFX utilizes ISO-MODs for input and output functions. ISOMODs are epoxy encapsulated electronic input/output modules that are simple to install and replace in the field. See Figure 1.10. All modules are 2,500 V optically isolated from MFX power and earth grounds. This eliminates the potential for ground loops and reduces the chance of severe damage in the event of an electrical surge. Figure 1.
PART 1 - ISO-MOD 4-20 mA Output The 4-20 mA Output Module interfaces with most recording and logging systems by transmitting an analog current signal that is proportional to system flow rate. The 4-20 mA ISO-MOD may be configured via jumper selections for either an internally powered mode (current sourcing) Figure 1.11A or externally powered mode (current sinking) Figure 1.11B. Internal Power Configuration: Ensure that jumpers are in place at JP1 and JP2 on the module. See Figure 1.11A.
PART 1 - ISO-MOD Control Relay Two independent SPDT (single-pole, double-throw) Form C relays are contained in this module. The relay operations are user configured via software to act in either a flow rate alarm, signal strength alarm or totalizer/batching mode. The relays are rated for 200 Vac maximum and have a current rating of 0.5 A resistive load (175 Vdc @ 0.25 A resistive).
PART 1 - ISO-MOD Rate Pulse The Rate Pulse Output Module is utilized to transmit information to external counters and PID systems via a frequency output that is proportional to system flow rate. The frequency output range of the Rate Pulse Module is 0–2,500 Hz. This module has two types of outputs: one simulates the output of the coil of a turbine flow meter, and the other is an open-collector type that does not source voltage at its output. Both outputs may be connected simultaneously.
PART 1 - ISO-MOD RS232C The RS232C Module will interface with the serial communication ports of PCs, PLCs and SCADA systems that are used to monitor flow rate information in piping systems. A proprietary digital communications protocol is used for this communication. An explanation of the command structure is detailed in the Appendix of this manual. Flow rate, total, signal strength and temperature (if so equipped) can be monitored over the digital communications module.
PART 1 - ISO-MOD RS485 The RS485 Module allows up to 128 MFX systems to be placed on a single three-wire cable bus. All meters are assigned a unique one byte serial number that allows all meters on the cable network to be independently accessed. A proprietary digital communications protocol is used for this communication. An explanation of the command structure is detailed in the Appendix of this manual.
PART 1 - ISO-MOD Data Logger The 200,000 event data logger/electronic stripchart recorder can be configured to match most user applications. The logger stores timestamped, high resolution (16-bit) data at user selected intervals ranging from 1 to 1,000 seconds. Configuration of and data retrieval from the logger are detailed in Sections 3 and 4 of this manual. The module can be carried in a shirt pocket back to the office and plugged into a PC serial port via the module’s integral DB-9 connector.
PART 1 - INSTRUMENT STARTUP Before Starting the Instrument NOTE: The MFX flow meter system requires a full pipe of liquid before a successful startup can be completed. Do not attempt to make adjustments or change configurations until a full pipe is verified. Instrument Startup Procedure: 1. Verify that all wiring is properly connected and routed as described in Part 1 of this manual. 2. Verify that the MagProbe sensor is properly mounted as described in Part 2 of this manual. 3. Apply power.
PART 2 - MAGPROBE INSTALLATION After unpacking, it is recommended to save the shipping carton and packing materials in case the instrument is stored or re-shipped. Inspect the equipment and carton for damage. If there is evidence of shipping damage, notify the carrier immediately. MagProbe Mounting Considerations Step A Mounting Locations The DMP insertion probe that is utilized by the MFX flow meter system contains an electromagnet, electrodes and amplification circuitry.
PART 2 - MAGPROBE INSTALLATION 1 Table 2.1 - Straight Pipe Recommendations 1 The MFX system will provide repeatable measurements on piping systems that do not meet these requirements, but the accuracy of these readings may be influenced to various degrees. Rev. 01/11 -2.
PART 2 - MAGPROBE INSTALLATION Step B Hot-Tapped Installation The installation instructions cover hot-tapped installations (installations where it is required to install or remove the MagProbe without shutting down the process pressure). If the product is being installed without an isolation valve, ignore the steps that pertain to its installation. Figure 2.2 illustrates an exploded view of an isolation valve assembly and names the various components.
PART 2 - MAGPROBE INSTALLATION Step C Component Assembly These instructions call for the use of a drilling machine designed for drilling holes in pipes that are under pressure (for example, Muller Co., Decatur, Illinois manufactures products for this purpose). Procedures are as follows: 1. Verify that the line pressure within the pipe is within the rated limits of the pressure drilling machine, welded coupling or pipe saddle, valve and MagProbe to be used. 2.
PART 2 - MAGPROBE INSTALLATION Step D Probe Insertion Distances PROBE INSERTION Before inserting the MagProbe into the piping system, it is necessary to calculate the probe insertion depth that will place the measuring electrodes at the proper position in the pipe. In order to complete this calculation, some knowledge of the piping system must be known. Refer to the paragraphs that follow and Figure 2.3 for information regarding this process.
PART 2 - MAGPROBE INSTALLATION TO CALCULATE INSERTION DEPTH Measure and record the following linear distances: E = PROBE LENGTH Installation Measurements: DMP2 through DMP6 MagProbes = _______ C = INSERTION FITTING to PIPE WALL = _______ B = PIPE WALL THICKNESS = _______ A = 0.125 x PIPE ID = _______ D = INSERTION DEPTH = _______ D=E-C-B-A Figure 2.3 Installation Measurements Rev. 01/11 -2.
PART 2 - MAGPROBE INSTALLATION Step E Cable Routing PROBE CABLE Before inserting the MagProbe into the pipe, the sensor cables should be routed to the transmitter location. Locate the transmitter within the length of MagProbe cable that was supplied with the MFX system. If this is not possible, replace the entire length of interconnect cable with Belden® part number 9536, Dynasonics part number D005-1003-003 or equivalent.
PART 2 - MAGPROBE INSTALLATION Step F MagProbe Insertion DMP2 through DMP6 MAGPROBE INSERTION DMP2 through DMP6 1. Apply sealant to the 1-½" NPT threads of the insertion fitting assembly. Screw the assembly into the isolation valve and tighten with a 2-½" pump wrench. Final orientation of the two threaded rods on the MagProbe insertion fitting should be approximately perpendicular to the pipe’s axis. 2.
PART 2 - MAGPROBE INSTALLATION 4. Slowly open the isolation valve. When the valve is fully open, use a 9/16" wrench on the insertion nuts, alternately tightening each nut about two complete turns to avoid uneven seal loading—two 9/16" ratcheting wrenches can expedite this process. Repeat until the length of probe remaining above the seal fitting equals the “D” length calculated in step D.
PART 3 - KEYPAD CONFIGURATION General After installation of the MagProbe sensor and connection of appropriate power supplies to the MFX, keypad configuration of the instrument can be undertaken. All entries are saved in non-volatile FLASH memory and will be retained in the event of power loss. The DMFXD2 is configured through the keypad interface and the DMFXD1 is configured through a software utility at the Dynasonics factory.
PART 3 - KEYPAD CONFIGURATION 3. The ENTER key is pressed from the RUN mode to view the current software version operating in the instrument. x Used to access the configuration parameters in the various menus. x Used to initiate changes in configuration parameters. x Used to accept configuration parameter changes. Menu Structure The MFX software is structured using menus. A Map of the user interface has been included in the Appendix of this manual.

PART 3 - KEYPAD CONFIGURATION Engineering Units—TOTAL Exponent TOTL E -- Flow Totalizer Exponent Value E-1 to E6 Utilized for setting the flow totalizer exponent. This feature is useful for accommodating a very large accumulated flow. The exponent is a “ 10 n” multiplier, where “n” can be from -1 ( 0.1) to +6 ( 1,000,000).Table 3.5 should be referenced for valid entries and their influence on the DMFX display. Table 3.5 - Totalizer Exponent Values Minimum Flow Rate Exponent Display Multiplier E-1 0.
PART 3 - KEYPAD CONFIGURATION Low Flow Cut-off FL C-OFF -- Low Flow Cut-off Percent of MAX RATE A Low Flow Cut-off entry is provided to allow very low flow rates (that can be present when pumps are off and valves are closed) to be displayed as Zero flow. Typical values that should be entered are between 1.0% and 5.0% of full-scale. System Damping DAMP PER -- System Damping Relative Percent Entry DAMP PER establishes a maximum adaptive filter value.
PART 3 - KEYPAD CONFIGURATION 2. OUTPUT #1 MENU 4-20mA ISO-MOD 4-20mA FL 4MA FL 20MA CAL 4MA CAL 20MA 4-20 TST Configured via jumper selections into either a passive or active transmission mode (see Section 2 for details), the 4-20 mA Output Module interfaces with virtually all recording and logging systems by transmitting an analog current signal that is proportional to system flow rate. Independent 4 mA and 20 mA span settings are established in software using the Flow Measuring Range entries.
PART 3 - KEYPAD CONFIGURATION For example, to span the 4-20mA output from 0 GPM to +100 GPM, with 12mA being 50 GPM, set the FL 4MA and FL 20MA inputs as follows: FL 4MA = 0.0 FL 20MA = 100.0 4-20mA Calibration The 4-20mA ISO-MOD is factory calibrated and should not require adjustment unless it is replaced. The CAL4MA entry allows fine adjustments to be made to the “zero” of the 4-20mA output. To adjust the 4mA output, an ammeter or reliable reference connection to the 4-20mA output must be present.
PART 3 - KEYPAD CONFIGURATION 4-20mA Test 4-20 TST - 4-20mA Output Test 4-20 Allows a simulated value to be output on from the 4-20mA output. By incrementing this value, the 4-20mA output will transmit the indicated current value. This feature can be utilized to confirm connectivity with chart recorders, data acquisition systems or other monitoring equipment. Rate Pulse/ Freq ISO-MOD RATE PULSE (Value) Flow at 0 Hz Flow at 2.5k Hz (FL 0H) (FL 2.
PART 3 - KEYPAD CONFIGURATION For example, in a bi-directional system, to span the 0 to 2.5k Hz output from –100 GPM to +100 GPM, with 1.25k Hz being 0 GPM, set the FL 100H and FL 10KH inputs as follows: FL 0H = –100.0 FL 25KH = 100.0 For example, to span the 0 to 2.5k Hz output from 0 GPM to +100 GPM, with 1.25k Hz being 50 GPM, set the FL 0H and FL 25KH inputs as follows: FL 0H = 0.0 FL 25KH = 100.
PART 3 - KEYPAD CONFIGURATION For example, if the Totalizer Exponent is set to E0 ( 1) and the Relay Multiplier is set to 1, then the relay will pulse each time the totalizer increments one count, or each single, whole measurement unit totalized. If the Totalizer Exponent is set to E2 ( 100) and the Relay Multiplier is set to 1, then the relay will pulse each time the display totalizer increments or once per 100 measurement units totalized.
PART 3 - KEYPAD CONFIGURATION RS232C Module ISO-MOD RS232C Baud Rate 1200 Baud 2400 Baud 9600 Baud 19,200 Baud (RS232 BA) (1200) (2400) (9600) (19200) The RS232C Module can be interfaced with serial communication ports of PCs, PLCs and SCADA systems. This module runs a proprietary digital protocol, detailed in the Appendix of this manual, that is used to monitor flow rate information in piping systems.
PART 3 - KEYPAD CONFIGURATION ADDRESS Each MFX connected on the communications bus must have an unique address number assigned. Address 127 is a universal address that will result in all MFX instruments on the network responding simultaneously—regardless of address—resulting in CRC errors. Only select address location 127 if one meter is on the network. Data Logger Option ISO-MOD DATALOGGER (Value) LOGGING INTERVAL From the OUTPUT 1 menu, select the time INTERVAL between readings.
PART 3 - KEYPAD CONFIGURATION 3. SECURITY MENU The SEC MENU allows the user to make password revisions, reset the flow totalizer and reset the transmitter microprocessor. Totalizer RESET TOT RES NO YES Select YES to reset the Positive, Negative and Net flow totalizer/ accumulator to Zero. System RESET SYS RSET NO YES Select YES to initiate a microprocessor reset. All system configurations and totalizer values will be maintained.
PART 3 - KEYPAD CONFIGURATION Substitute Flow Entry SUB FLOW - Substitute Flow Substitute Flow or SUB FLOW is a value that the analog outputs and the flow rate display will be driven at when an error condition in the flow meter occurs. The typical setting for this entry is a value that will make the instrument display zero flow during an error condition. TABLE 3.2 below lists some typical settings to achieve “Zero” with respect to MIN and MAX FLOW settings. TABLE 3.
PART 3 - KEYPAD CONFIGURATION Factory Default Zero Calibration D-FLT 0 -- Reverting to Factory Default Zero Correction Factor COR FTR -- Universal Correction Factor If the flow in a piping system cannot be shutoff, allowing the SET ZERO procedure described above to be performed, the factory default zero should be utilized. To utilize the D-FLT 0 function, simply press ENTER, then press an ARROW key to display YES on the display and then press ENTER.
PART 3 - KEYPAD CONFIGURATION Totalizer Display Mode TOTAL -- Totalizer Mode NET POS NEG BATCH Select NET to display the net difference between the positive direction and negative direction totalizers. Select POS to only view the positive direction totalizer. Select NEG to only view the negative direction totalizer. Select the BATCH totalizer to configure the totalizer to count up to a value that is entered as BTCH MUL (described on the following page).
