KDA Doppler Pipe Sensor

Part No. KDA-R/KDS-R

Flow velocity sensor for installation in pipes

Ultrasonic sensors for flow measurement in slight to heavily polluted media. Designed for fastening in pipes using a nozzle

  • Latest fourth-generation intelligent <link https: www.nivus.com en service-download know-how doppler external-link-new-window>Doppler technology
  • Cost-effective pricing
  • Suitable for all channel cross sections
  • Easy to install without the need for additional constructions
  • Cables can be extended without any problems
  • 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
