POA Correlation

• For high-accurate flow measurement by means of ultrasonic cross correlation method
• Interference-free connection over long distances through digital signal transmission
• Cables can be extended without any problems using standard cables
• Absolutely stable zero point and drift-free
• Measurement in heavily polluted and abrasive media
• Easy installation without additional constructions and perfectly matched mounting accessories
• Installation under process conditions possible
• Suitable for all channel cross sections
• The tailored selection of sensor constructions ensures the best possible solution for each application

POA 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 NivuFlow 750 and an external level measurement the result is a complete flow measurement system.

Typical applications for POA 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
