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