Clean-water plants, wastewater treatment works, desalination and lift stations all need continuous, maintenance-free level data — but each presents its own headache: foam on aeration basins, turbulence in wet wells, sludge build-up, and open-channel flow that has no stilling well. The wrong sensor clogs, drifts or reads nothing within months.
For non-contact measurement on clean water tanks, balance tanks and sewage sumps, the integrated ultrasonic level transmitter gives a maintenance-free 5 cm blind zone and a calibrated 4–20 mA / RS485 output. It is the cost-effective default where the surface is reasonably clean.
Where foam, vapours or pump surges defeat ultrasonic, the 80 GHz FMCW radar ignores them: a narrow 3° beam rejects wall and agitator echoes, and ±2 mm accuracy holds through condensation. This is the safe choice for wet wells and aeration basins.
Stations with no power or no wired network use the 4G solar wireless monitor: solar + battery, three years of data traffic included, zero monthly fees, data pushed to the cloud.
Only non-contact radar or a properly aimed ultrasonic. Foam attenuates an ultrasonic pulse; 80 GHz radar penetrates it. Avoid contacting probes in aerated basins.
Measure level at a flume or weir and compute flow from the level–flow curve. We can supply the radar or ultrasonic head plus the 4G logger to push both level and derived flow to your SCADA or cloud dashboard.
