The system can be used to calibrate water level instruments based on hydrostatic pressure measurement - submersible water level sensors and bubblers. It uses a gauge pressure generator with a built-in reference sensor.

An automated pressure controller simulates water depth by creating a stable pressure difference against the ambient atmosphere. Calibrated sensors are connected by dedicated tubing and flanges professionally designed to create an air-tight homogeneous pressure. The reading of the sensors is compared to a reference pressure sensor. We automate the calibration process where possible. The software controls the controller pressure and takes readings from the reference pressure sensor. Electronic water level sensors can be calibrated automatically.
