Hydrostatic Water Level Sensor

Hydrostatic water level sensor for a.o. wastewater pump control. Water levels from 0 to 2000 mm can be set for ideal pump activation.


  • Ensure the measured media is compatible with the contacting materials of the water level sensor
  • Also pay attention to media density in the measurement
  • Maintenance should be done by qualified personnel
  • Wear protective gloves during maintenance
  • Clean the water level sensor with a wetted cloth, without applying pressure to the membrane inside the probe. The membrane can be damaged when the protective cap is removed

  • Mount the water level sensor in a fixed place, avoid sideways movements, these can lead to incorrect measurements
  • Shield the level sensor from foreign solid object in the measured medium
  • Do not bend the wire in a radius
  • When shortening the wire, ensure the referential tube is open on the end side
  • Ensure the cable ends in a proper terminal housing with air compensation filter
