Hydrostatic Level Transmitters
A hydrostatic level transmitter is a pressure sensor suspended on its cable at the bottom of a tank or well. It measures the pressure of the liquid column above it and converts it into an analogue signal corresponding to liquid height.
The store range includes submersible transmitters with 3, 5 and 10 metre water column ranges and a 1000 mbar, 10 m range model with 4–20 mA output. They are used for continuous level measurement in wells, tanks, wastewater pits and open channels.
Main Applications
- Deep well and borehole level
- Water tanks and reservoirs
- Wastewater and lift station pits
- Rainwater tanks
- Booster and pump control

Which material? Hydrostatic measurement depends on liquid density; for liquids with a density different from water, the range is corrected for density. Keep the junction box in a dry place so the cable’s vent tube does not clog.
