Abstract

PURPOSE:To eliminate the error of transmission time between the transceiver and piping, by providing the auxiliary oscillator receiving the ultrasonic wave from the oscillator for transmission and reception waves at the position corresponding to the transmission time between the transceiver and the piping. CONSTITUTION:The transceivers 12, 13 having the oscillators 17, 18 and auxiliary oscillators 19, 21 are fitted to the pipe 1 through which the fluid passes. The transceivers 12, 13 are of the same shape and the center line of the main directivity characteristics of the oscillator 17 and auxiliary oscillator 21 fitted to the surfaces 23, 24 with a slope as shown in figure is crossed with the contact surface 22 of the piping 11. In the transceiver located in this way, since the transmission time between the oscillator 17 and the auxiliary oscillator 21, and the transmission time between the oscillator 17 and the piping 11, and between the piping 11 and the oscillator 19 are equal, and when the difference of the outputs of the detection circuits 31, 32 of the auxiliary oscillator 21 and the oscillator 19 is obtained as the output of the conversion circuit 33, the time of transmission of ultrasonic waves in the fluid to be measured can actually be obtained.
