Chapter 1 Unpacking the H-310 1.1 Unpacking the H-310 The following is a list of items you should have received: WATERLOG® H-310 pressure transducer with polyethylene vented cable and H-305 Dry Air System A one pound cement ballast Three spare desiccant packs The H-310 Owner's Manual Stainless steel suspension cable and miscellaneous hardware (optional) Figure 1-1 Be sure that the vented cable is long enough to reach from the depth location selected to the junction box of the dry air system.
1.2 Checking the Model Number Before installing your new WATERLOG® H-310, check the information on the label of the sensor enclosure. Check the model number, the range, and the output type to be sure that you have received the instrument you ordered. The label will look similar to the following: Model: Range: Output: Input: S/N: H-310 0-15 psi SDI-12 9.6 to 16.0 volts 12345 This example shows that the WATERLOG® H-310-15 measures pressure within the range from zero to 15 psi.
Chapter 2 Installation 2.1 Installing the WATERLOG® H-310 and the H-305 To install the WATERLOG® H-310 sensor and the H-305 dry air system, simply deploy the H-310 at the desired location and connect the hook-up cable from the H-305 junction box to your data logger. 2.1.1 Sensor Deployment There are as many ways to deploy the H-310 as there are customers. However, as versatile as the H-310 is, there are some site preparations and maintenance that must be considered. 1.
Figure 2-1 3. The H-305 dry air system should be placed in an easily accessible spot. This allows the user to maintain the desiccant, and if needs be, the wiring inside the junction box. The H-305 dry air system is designed to protect the sensor from moisture accumulation. The desiccant inside the dry air system should be checked every 3 to 6 months. The desiccant bags have a transparent strip which allows the condition of the desiccant to be visually checked.
2.1.2 Environmental Concerns Through years of experience dealing with measuring in the environment, we have learned that Mother Nature is very unforgiving to electronic equipment. There are several environmental concerns with respect to installation and use of the H-310. 1. Although the H-310 is submersible, it cannot be frozen. Damage will occur to the sensor if it is frozen.
2.4 Connecting the Hook-up Cable If the hook-up cable from the junction box to your data recorder needs to be modified or changed, see Figure 2-2 and follow these steps: Step 1- Remove the lid from the junction box by loosening the two corner screws. Step 2- Loosen the gland nut on the data recorder end of the junction box. Step 3- Pull enough hook-up cable to work with through the watertight fitting. Then strip the PVC coating from the cable end (about two inches).
Figure 2-2 Step 5- With a small screw driver, loosen the screw of the terminal strip to open each slot where you want to insert a wire. Step 6- Insert the wires. Step 7- Tighten the screw down while holding the wire in place. Step 8- Check to make sure each wire is connected securely in the correct slot. Step 9- Tighten the gland nut so it grips your hook-up cable tightly. Step 10- Replace the lid and screw the lid down on the junction box. Step 11- Check your desiccant packs. Replace if necessary.
2.5 Connecting Your Data Recorder Your selected data recorder must be capable of reading the type of signals (SDI-12 or RS-232) output by your specific WATERLOG® model. Connect the hook-up cable coming from the junction box to the appropriate port of your data recorder, either SDI-12 or RS-232. Note: The RS-232 option will require that you use an H214 SDI-12 to RS-232 converter between your data recorder and the WATERLOG® H-310.
Chapter 3 Operation 3.1 Operation The WATERLOG® H-310 is easy to use and works with many data recorders. Its internal microprocessor automatically compensates for error due to offset, non-linearity, and temperature changes. The H-310 outputs pressure and temperature measurements in psi units and degrees centigrade. SPECIAL NOTE: The WATERLOG® H-310 is a very sensitive instrument with special temperature sensing circuitry.
3.2 Reading Data from the H-310 Since data recorders differ widely, you must prepare your data recorder to receive and display the H-310 data according to the recorder manufacturer's directions. User requirements also differ. Users may program their data recorders individually for such variables as sampling rates. The following information is provided to help you customize your system according to the data recorder you will use and your data requirements: SDI-12.
Chapter 4 Maintenance 4.1 Maintenance Sustained operation is almost maintenance-free. Our experience tells us moisture creates the largest percentage of field problems. Therefore, monitoring the desiccant is of prime importance. Desiccant in the H-305 dry air system should be changed periodically, normally every three to six months. 4.2 H-305 Maintenance Procedure Regular maintenance of the H-305 desiccant is imperative.
Figure 4-1 H-305 Dry Air System 4.3 Cleaning the Port Screen Occasionally the port screen and the pressure ports may need to be cleaned, rinsed out or replaced . Replacement screens are available if needed. Figure 4-2 below shows the location of the stainless steel screen at the end of the sensor housing. To remove the stainless steel screen follow these steps. Step 1- Force the rubber bumper ring up onto the enclosure. This rubber ring may be stiff, but it will move. Be careful not to tear the ring.
Step 4- Rinse the pressure ports with water to clear mud and silt. You may want to swish the H-310 in a bucket of water or in the stream it is monitoring to rinse out the pressure ports. CAUTION: Be careful not to create large pressures by using sticks and the like to push debris out of the way. This may cause a plunger effect, and thus over pressure the H-310. USE COMMON SENSE. Step 5- Replace the plastic filter and the stainless steel screen. Position the joints of the two screens 180 apart.
4.4 Maintaining Desiccant Packs The desiccant inside the dry air system should be checked every 3 to 6 months. The desiccant bags have a transparent strip which allows the condition of the desiccant to be visually checked. Dry desiccant is dark blue and saturated desiccant will have turned pink. The desiccant packs can be reused by drying them in an oven at 125 F to 150 F for 4 to 8 hours or until the desiccant returns to a dark blue color. 4.

Appendix C SDI-12 Command and Response Protocol C.1 SDI-12 Command and Response Protocol This is a brief description of the Serial Digital Interface (SDI-12) Command and Response protocol used by the WATERLOG® H-310 sensor. Included is a description of the commands and data format supported by the H-310. Refer to the document "A SERIAL DIGITAL INTERFACE STANDARD FOR HYDROLOGIC AND ENVIRONMENTAL SENSORS" for a complete description of the SDI-12 protocol. Version 1.
C.2 Initiate Measurement Command Command Response Description "aM!" "atttn" Initiate measurement "aM1!" - "aM9!" "atttn" Additional measurement commands Where : a is the sensor address (0-9,*). M (or M1 thru M9) are upper-case ASCII characters ttt is a three digit integer (000-999) specifying the maximum time, in seconds, the sensor will take to have measurement data available in its buffer.
C.3 INITIATE VERIFY COMMAND Command "aV!" Response Description "atttn" Initiate verify sequence Where: a Is the sensor address (0-9,*). V Is an upper-case ASCII character. ttt Is a three digit integer (000-999) specifying the maximum time, in seconds, the sensor will take to have data available in its buffer. n Is a single digit integer (0-9) specifying the number of values that will be placed in the data buffer. If "n"is zero (0), no data will be available using subsequent "D" commands.
The Send Data command returns sensor data generated as the result of previous "aM!" or "aV!" commands. Values returned will be sent in 33 characters or less. The sensor's data buffer will not be altered by this command. If the number of values returned by a "aD0!" command is less than the number specified by the result of the previous "M" or "V" command, the rest of the data must be collected using "aD1", "aD2!" .... and so on until all values specified have been collected.
