GEMÜ C38 SonicLine
Ultrasonic flowmeter
GEMÜ C38 SonicLine is an ultrasonic flowmeter operating according to the phase difference method. Two sensors in opposite position reciprocally send and receive ultrasonic signals. With a standing medium, both sensors receive the sent ultrasonic signals within the same phase, i.e. no difference in phase occurs. With a flowing medium a phase shifting 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.
