OTT CBSThe bubble type water level sensor can accurately measure the water level for a long time. Using the zero drift measurement principle, the water level measurement range is0...30mThe system adopts non-contact measurement technology to ensure the principle of pressure measurement unit and electronic components on the water surface.

The sensor is equipped with a piston pump that provides compressed gas for water level measurement. Compressed gas is introduced into the measuring chamber at the bottom of the water through a measuring pipeline, and finally the pressure of the measuring pipeline reaches equilibrium with the water pressure at the measuring chamber. The pressure unit built into the sensor detects atmospheric pressure and measures pipeline pressure. Calculate the accurate water level after compensating for air pressure by the difference between these two pressures.

The built-in piston pump can accurately generate an appropriate amount of compressed gas, complete water level measurement while minimizing condensation. At the same time, it can reduce energy consumption and extend the service life of piston pumps.
