KDA Doppler Wedge Sensor
Part No. KDA-K/KDS-KWedge-shaped flow velocity sensor for channels
Ultrasonic sensors for flow measurement in slight to heavily polluted media. Wedge shape for installation on channel wall or channel bottom
Description
- 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
- Built-in pressure cell mechanically protected
KDA flow velocity sensors are suitable for continuous measurement of slight to heavily polluted media. The wedge-shaped sensors are designed for installation on either the channel wall or the channel bottom.
Combined with transmitter types such as PCM F and OCM F the result is a complete flow measurement system.
Typical applications for KDA wedge 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
- Measurement campaigns in channel networks
- and many more
