Abstract

PURPOSE: To ensure the accurate measurement of the flow rate with no effect of the current transformation, by connecting in switching each pair of ultrasonic transducers to the single current speed measuring circuit in sequence.
CONSTITUTION: Ultrasonic transducers 21W24 are provided to the flow path of fluid 2, and then the switching is given via line measurement switch 26 to two types of ultrasonic waves which are propagated in fluid 2 and along two types of measurement lines formed by two pairs of transducers and crossing each other. And then the measurement is carried out by means of a unit of TTL current speed measuring circuit 25. For the switching cycle of the measurement lines, the switching is given between measurement lines 21-22 and 23-24 iva measurement line switch 26 as well as switch control circuit 27 doubling as a timer circuit, and then the switching is given between measurement output signals F1 and F2 by output switch 28. Thus the measurement is carried out via the different output signals. As a result, the accurate measurement is possible for the current speed of the fluid having the current transformation which changes in terms of the time and the space.
