Measurement in heavily polluted and abrasive media

KDA flow velocity sensors are suitable for continuous measurement of slight to heavily polluted media. The pipe sensors are designed for installation in pipes from the outside using a nozzle. Combined with transmitter types such as PCM F and without OCM F the result is a complete flow measurement system.

Typical applications for KDA pipe sensors

Wastewater treatment plants: intake, discharge, activated sludge tank intakes, return sludge, recirculation, surplus sludge, digester discharge and flocculant dosage
Permanent measurements on stormwater treatment facilities such as stormwater overflow tanks, rainwater sedimentation and retention tanks
Direct discharge control, infiltration (extraneous water) or leakage detection
Industrial wastewater networks
and many more
