Ultraschall-Durchflussmesser

The GEMÜ C38 SonicLine is an ultrasonic flowmeter that works according to the phase difference method. Two sensors opposite each other alternately send and receive ultrasonic signals. With a standing medium, both sensors receive the sent ultrasonic signals within the same phase, i.e. no phase difference occurs. With a flowing medium, a phase shift takes place. This phase difference is directly proportional to the flow velocity. The flow volume is determined from the flow velocity and the pipe diameter.
