Ultrasonic Flowmeter stationary • portable for liquids Model DUC Description DUC uses the effect of acceleration and deceleration of acoustic signals travelling in a moving liquid. Two ultrasonic clamp-on transducers are mounted (from outside) on a pipe and produce an acoustic path. The transducers send and receive acoustic signals and the transit times t1 and t2 are measured by an electronic flow transmitter. The signal from transducer A towards transducer B is accelerated by the flow (short t1). The return signal from transducer B to transducer A is decelerated by the flow (longer t2). The...

Ultrasonic Flowmeter stationary ∙ portable for liquids Model DUC Measurement of heat quantity DUC-M is more than a flowmeter. Together with external temperature sensors it can also measure the heat transfer of your media. Only two optional Pt  100 have to be connected to DUC-MF for measuring feed  return temperatures (RTD /  1 / RTD 2) within the heating circuit. The measured temperature difference and the measured flow Q can then be used to calculate the thermal output and the heat quantity. Heat flow / heat quantity Flow / volume Feed temperature ??? Return temperature transmitter No responsibility...
