CRS451/CRS456 Submersible Water-Level Recording Sensor 1. Introduction The CRS451 consists of a water-level and water-temperature sensor that has its own time clock and memory to store the collected data, in a compact stainlesssteel case. This frees users to place the sensor in remote sites and let it collect data for long periods of time.

CRS451/CRS456 Submersible Water-Level Recording Sensor CAUTION Freezing conditions may damage the CRS451/CRS456 (see Section 6.2, Avoiding Freezing Conditions, for more information). Body Material CRS451: CRS456: 316L Stainless Steel Titanium Element Material CRS451: CRS456: 316L Stainless Steel Hastelloy® Standard Cone Material: Delrin® Weighted and NPT Material: Stainless Steel Dimensions Length: Diameter: 22.23 cm (8.75 in) 2.22 cm (0.875 in) Weight: 230 g (0.
CRS451/CRS456 Submersible Water-Level Recording Sensor CAUTION The output reading will not be correct, and the transducer can be damaged if pressure is twice its pressure rating. Pressure can be converted to feet of fresh water using the following simple equation: 1 psi = 2.31 feet of water For example, the maximum depth with a pressure range of 0 to 7.25 psig is 16.748 feet of water. 6.2 Avoiding Freezing Conditions Expansion of water due to freezing will irreparably damage the CRS451/CRS456.
CRS451/CRS456 Submersible Water-Level Recording Sensor 6.5 Other Installations The CRS451/CRS456 can be installed in any position; however, when it leaves the factory it is tested in the vertical position. There will be an offset error if not installed vertically; contact Campbell Scientific for more information. Strapping the transducer body with tie wraps or tape will not hurt it. 6.

CRS451/CRS456 Submersible Water-Level Recording Sensor 7. Programming Communicating with the CRS451/CRS456 requires a micro USB cable and HydroSci software running on a computer with Windows XP or later. The CRS451/CRS456 is configured using the HydroSci software provided with the unit. A DVD containing HydroSci is shipped with the CRS451/CRS456. CAUTION 7.1 If you are using an XP computer, please have the driver disc in the CD/DVD drive before plugging in the USB cord.
CRS451/CRS456 Submersible Water-Level Recording Sensor 7.3 Configure CRS45X for Measurements 1. Click Configuration. 2. Select Create New Configuration button located at lower left of screen. 3. Select the type of measurements you want to make. a) NOTE Barometer Pressure Reference should be selected if you want to use CR45X sensor as a barometer to compensate for changes in barometric pressure. See Section 7.4.
CRS451/CRS456 Submersible Water-Level Recording Sensor 4. Add offset to relate water level measurements to a known datum or reference point. (Aquifer test start at level 0.) a) This step is optional and not required. b) This offset takes effect at the Start Time—which is set in a subsequent screen—so it is necessary that this sensor be in its permanent measurement position before the Start Time, otherwise the offset correction will not be correct. 5. Select a Start and Stop Time.
CRS451/CRS456 Submersible Water-Level Recording Sensor b) If desired, select time in future when measurements should cease. c) Select the rate at which measurements will be made. This does not configure the senor for data storage, only the rate at which measurements are made.
CRS451/CRS456 Submersible Water-Level Recording Sensor 6. Select and Name Data Tables for Datalogging. a) Up to four different Data Tables can archive data at independent intervals with any combination of elements (samples, averages, maximum, etc). b) Contents of the Data Table are selected in the next screen.
CRS451/CRS456 Submersible Water-Level Recording Sensor 7. Select which data, in which format and unit of measurement, is to be included in each of the data tables selected in the previous screen.
CRS451/CRS456 Submersible Water-Level Recording Sensor 8. Once the Data Tables have been configured, the configuration process is finished and the Finish button can be selected. 9. Once the configuration is complete, it must be copied to the CRS451 before it will take effect. Click on Apply Configuration to CRS45X to start this process. Before sending the configuration file to the CRS45X, HydroSci may provide a warning that your start and stop times may need adjusting.
CRS451/CRS456 Submersible Water-Level Recording Sensor 7.4 Compensating Measurements for Barometric Pressure The CRS45X pressure transducer is unvented; therefore it is monitoring sealed gage pressure and should be corrected for barometric pressure. 7.4.1 Using an Additional CRS45X One simple way to complete this correction is to deploy an additional CRS45X as a reference sensor. For this method, in the Select Field Application window, choose Barometer Pressure Reference (see Section 7.
CRS451/CRS456 Submersible Water-Level Recording Sensor 2. Select a data file you wish to be corrected by barometric pressure values. a) 3. 16 The Field Application Used to Produce Collected Measurement Data information will be shown based on the collected data file selected. Press the browse button next to the Barometric Pressure Reference Data File field to browse the data files from the barometric reference sensor.
CRS451/CRS456 Submersible Water-Level Recording Sensor 4. Select a data file you wish to use as the barometric pressure reference data file. a) Use the drop-down list to select the Barometric Pressure Reference Column in the data file. The reference column must be a measurement of pressure or level. If from a nearby Campbell Scientific weather station, note that the reference column must have units associated with it.
CRS451/CRS456 Submersible Water-Level Recording Sensor 5. Press the browse button next to the Corrected Data File field to indicate where the corrected data file should be stored. Rename the file as applicable. 6. After completing all of the fields, press the Build Corrected Data File button. 7. Once the corrected data file has been built, press the View Corrected Data File button to open the file in View. The View Data button at the bottom of the screen can also be used to open View.
CRS451/CRS456 Submersible Water-Level Recording Sensor In View, use the File | Open menu item to browse to any data file you would like to view. To select the data values to be graphed, click on the column heading(s) in the data file with a single mouse click. The selection will be highlighted and will automatically be added to the graph. Multiple columns can be added by holding the Ctrl key and dragging the mouse pointer over the column headings. To see the graph, press the Graph button.

Maintenance Campbell Scientific recommends that the CRS451/CRS456 be factory recalibrated every 24 months. Before a CRS451/CRS456 is sent to Campbell Scientific, the customer must get an RMA (returned material authorization) number and fill out the Declaration of Hazardous Material and Decontamination form. 8.1 8.2 Every Visit • Collect data.

CRS451/CRS456 Submersible Water-Level Recording Sensor Gently pull the battery out the end. Disconnect the battery. Remove the battery. Slide in the new battery. Plug in the new battery.
CRS451/CRS456 Submersible Water-Level Recording Sensor Slide the battery into the housing. Reconnect the cable.
CRS451/CRS456 Submersible Water-Level Recording Sensor Gently slide the end piece with its O-rings into the housing. NOTE Nicking the O-ring could result in a leak. Line up the holes and insert the set screw. Do not over tighten the set screw.
CRS451/CRS456 Submersible Water-Level Recording Sensor 9. Troubleshooting The most common causes for erroneous pressure transducer data include: • • • Low battery Damaged CRS451/CRS456 Water damage Damage to diaphragm due to excessive pressure Atmospheric pressure not subtracted from pressure reading Problem: Unit will not respond when attempting USB communications. Suggestion: Replace battery. Correct COM Port used for communication not selected in HydroSci.
Appendix A. Calibration Certificate Each CRS451/CRS456 has been calibrated to meet printed accuracy specification at multiple temperature and pressure ranges. If additional verification is required, a Calibration Certificate can be purchased for each CRS451/CRS456 Water-Level Recording Sensor. The Instrument Data Report provides a list of the pressure and temperature at which the sensor was tested. Pressure [kPa] is the pressure applied (listed in kilopascals) to the sensor.
