3. Installation Practices

4. Above Ground Monument Sensor Cable Well casing Strain relief Desiccant Service port Well cap Monument Steel or fiberglass monument Steel or fiberglass monument

5. Steel or fiberglass flush mounted lid Steel or fiberglass flush mounted lid Installation Practices Below Ground Monument Sensor Cable Well casing Strain relief Desiccant* Service port Well cap MonumentLid *Prone to flooding!! Keep desiccant dry or use absolute sensors.

6. Installation Practices Do not drop into well – Lower gently to prevent damage to end of sensor.

7. Installation Practices Do not scrape cable over edge of well – May nick or fray cable.

8. Installation Practices Do not bend cable sharply – This may close off vent tube*. *Gauge (vented) pressure sensors contain a vent tube inside the cable. If this vent tube is closed off, readings will be wrong.

9. Installation Practices Install in vertical position – Off vertical may introduce an offset.

10. Installation Practices Do not lower into mud or silt – This may clog or blind sensor.

11. Use a strain relief kit to prevent excess pulling on the cable. Installation Practices

12. Install so that service connector stays dry. Installation Practices

13. On vented pressure sensors… Install so as to keep desiccant dry. Installation Practices

14. Replace desiccant when it turns pink. Installation Practices Pink = Bad Blue = Good

15. Security Issues

16. Use locking monuments

17. Security Issues Paint to match surroundings plainpaintedplainpainted

18. Security Issues Surround with a fence

19. Security Issues Install caution signs or alarms

20. Security Issues Use passworded software

21. Security Issues Proprietary data formats and software

22. Changing Batteries

23. Should be done in a clean, dry environment to avoid contamination or moisture damage to the circuitry.

24. Changing Batteries Top- cap Cable O-rings AA batteries 1.Twisting gently, unscrew the top-cap. Note: Two O-rings provide a water-tight seal and often seal tightly. Pulling hard can cause the O-rings to release suddenly and the top-cap to disengage with enough force to pull the insides out of the sensor.

25. Changing Batteries 2.Gently separate the top-cap from the body of the sensor. Top-cap remains attached to body via several colored wires. 3.Gently slide batteries out. 4.Insert new batteries – positive terminals towards top-cap. 5.Replace and retighten top-cap.
