TRANSDUCER DEVICE OPERATING WITH ULTRASOUND FOR THE MEASUREMENT OF THE FLOW VELOCITY OF A FLUID IN A PIPE

摘要

A transducer device operating with ultrasound for the measurement of the flow velocity of a fluid in a pipe (1) comprising two transducers (2, 3) mounted on their respective sides of the pipe and directed obliquely in relation to the direction of the flow, which transducers alternately transmit and receive sonic pulses to, respectively from each other. The two transducers (2, 3) are designed with their centre axes deviating from the imaginary connecting line between the transducers in a direction against the mentioned flow direction (1).
