Water Level Temperature Sensor Field Notes

Tip:

It is recommended to take a manual water level measurement before installing a Water Level Temperature Sensor, shortly after installation, periodically during your monitoring interval, and at the end of your measurement period. Use these measurements to verify Water Level Temperature Sensor readings, and for data adjustments later on. Ensure you take manual readings as close in time as possible to a scheduled Water Level Temperature Sensor reading.

 

Note:

The WLTS can withstand over-pressurization of 2 times the intended range, e.g. a Model M10 can accommodate a fluctuation of 20 meters or 60 feet and still record pressure. However, over-range accuracy is not guaranteed.

Measurement Principles

Absolute Level:
When submerged, absolute pressure sensors measure total pressure – the pressure of air plus water column above their zero point. The actual pressure of just water above the sensor is obtained by subtracting barometric pressure from the total pressure.

Vented (Gauged) Level:
When submerged, vented pressure sensors detect both water and barometric pressure. However, a vent tube to surface allows barometric effects on the pressure sensor to be eliminated. Therefore, they provide readings of the actual pressure of just water above the pressure sensor zero point.

 

Deployment

 

 

 

After Deployment, make sure you do the following:

Once the Water Level Temperature Sensor has been installed and powered up, you can start configuring it.

 

Note:

See the 301 Water Level Temperature Sensor User Guide for your specific communication protocol (MODBUS, SDI-12) for full definitions of the available commands.
