Abstract

PURPOSE:To enable the flow measurement with high accuracy, independently of the installed position of receiver, characteristics, and time aging, by using one transceiver in common use of transmission and reception. CONSTITUTION:At the standstill of the fluid 1, the ultrasonic wave beam pattern emitted from the transceiver 10 with the excitation of the oscillation circuit 11 passes through the center of the transceiver 10, and is symmetrical with the vertical line to the axis line of the pipe 2, and the reflection wave level incident to the transceiver 10 takes maximum. Further, the output of the transceiver 10 is displayed 15 via the signal processing circuit 14. Next, when the fluid 1 flows, the beam pattern is tilted toward the fluid and the reflection waves incident to the receiver 10 is reduced. The output of the receiver 10 in this case is similarly displayed 15. Further, the flow can be known from the display value of two states of the fluid 1.
