Hydrostatic Level Transmitters
Water well, Process fluids, Wastewater
- Measurment Range
0-3 m, 0-30 m, 0-100 m, 0-300 m
Analogue 4-20 mA
The water level transmitters are designed for measurement under rough conditions in all water and wastewater applications with large concentrations of sludge and suspended solids.
Our level transmitters have a sturdy design with housing in re-enforced plastic or stainless steel. Cables are insulated with PUR, and steel reinforced to achieve very high tensile strength. Sensing membranes are made with either ceramic or stainless steel. Outputs are analog two-wire 4-20 mA, voltage or digital Modbus RTU.
The Expert Hydrostatic Level Transmitters line consist of these product types:
- Expert Hydrostatic Analogue Submersible Level Transmitters
- Expert Hydrostatic Digital Submersible Level Transmitters
- Level Transmitters for clean water applications
- Level Transmitters for waste water applications

Hydrostatic transmitters are used everywhere - even in some very harsh environments:
For level measurement in tanks with sewage, storm flow basins, aeration tanks, sludge thickeners and have enough precision for level measurement for open channel flow measurement.
Level measurement in water wells and tanks, level control in water towers, filter pools, ion exchangers and chemical mixing/precipitation tanks.
Level measurement in tunnels, mines and dewatering under larger buildings.
Measurement in all types of process tanks where with access from the surface, even in hazardous areas.
