The resistive piezometer is a transducer that measures relative pressure, allowing us to determine the piezometric height by measuring the hydrostatic pressure on the sensor. The sensor has a small tube inside its self-supporting cable connecting its reference room with the atmosphere. This ensures that any changes in environmental pressure affect the piezometric surface rather than the reference room. As a result, the device measures only water pressure, which indicates the water level.

Due to its compact and robust design and high-quality components, this level gauge is an excellent tool for monitoring and controlling water levels in piezometers, wells, pits, canals, tanks, rivers, lakes, and other bodies of water. The absolute version of the device determines interstitial pressure, while the relative version determines piezometric height in the piezometer pipe.
