Via the pressure sensor, the measurement system determines the water level from the pressure of the water column. This sensor with gold-coated ceramic membrane and stainless steel housing is compact, robust and durable. It is placed in a PVC stilling pipe below the lowest anticipated water level. When combined with a UGT data logger, the sensor can be calibrated to the installation depth and directly read out the water level from the water column resting on it.

The data are read out using an RS-232 interface on the data logger. The level measurement equipment itself exports the data via an RS-485 interface with a voltage output of 0-1 V. In order to be able to best adjust the measurement to the expected water level and the installation conditions , the pressure sensor is offered in three measurement ranges of up to 50, up to 100 and up to 200 cm water level.
