Belimo 22PF-1UH - ultrasonic flow sensor

Belimo 22PF-1UH – DN 50 flow sensor

The sensor uses ultrasonic flow measurement in closed cold and hot water systems. It measures the flow and temperature of the medium. During operation, it measures the glycol content and takes it into account in the flow measurement. Device parameters can be configured using Belimo Assistant 2.
