Abstract
PURPOSE:To enable accurate measurement of flow rate, by providing a means for completely removing a measured value of a fixed lag time which is a propagation time in a medium except for a fluid. CONSTITUTION:Ultrasonic transmission and reception units 2, 2' of the same characteristics are mounted on a conduit 1 so that the units obliquely face each other. Another ultrasonic transmission and reception unit 2'' of the same characteristics as the former units 2, 2' is provided in such a position that the unit 2'' can definitely receive ultrasonic pulses emitted from the electroacoustic transducer 3 of the unit 2 and reflected on the boundary between a fluid and the inside surface of the conduit. As a result, a measured value can be accurately and completely removed of the propagation time in a medium such as shoes 4, 4' and the conduit wall except for the fluid.
