The electric piezometers of the LV611 series measure pressures, interstitial overpressures and water levels in wells, dams, canals and reservoirs.
The LV611 series is divided into two categories: </ p>

• LV611-AS absolute piezometer , able to detect interstitial pressures in the ground and equipped with shielded electrical cable 4×0.22 with outer sheath marine grade scratchproof.
• LV611-RL relative piezometer , capable of detecting pressure hydrostatic, equipped with 4×0 shielded electrical cable .22 with tube for the atmospheric compensation and marine grade scratchproof outer sheath.

The piezometer, inserted in a well, performs a pressure measurement directly proportional to the height of the liquid contained in it. The electrical connection cable, being load-bearing, is fixed to the piezometer casing, allowing it to be inserted and recovered without problems. Inside the connection cable, a small tube connects the reference chamber of the transducer with the atmosphere, in order to compensate for variations in atmospheric pressure: the result is a relative pressure measurement.
A piezoelectric element, applied to a flexible metal membrane, converts the pressure into a directly proportional electrical signal.
The electrical connection cable of the piezometers is supplied in the desired length.
Each sensor is supplied with a test certificate certifying the results of the test performed and its electromechanical characteristics.
