Title: Ultrasonic flow meter
Inventor: NABESHIMA NORIYUKI
IPC: G01F1/66
Filed: 1995-07-21
Abstract: PROBLEM TO BE SOLVED: To improve the measuring accuracy of an ultrasonic flow meter using a sing-around method. SOLUTION: A time chart obtained when ultrasonic waves are emitted in the flow forward direction and the propagation delay time t1 is measured is shown in the figure. A transmitter is driven by a drive pulse P1 at the time of a start. The transmitter is vibrated to emit ultrasonic waves toward a receiver, and an electric signal S11 is generated. A third wave of S11 is detected by a detecting circuit to obtain a signal P11. A drive pulse P2 is applied to the transmitter by a signal P21 obtained when the third wave of an electric signal S21 of the receiver is detected. These actions are repeated, and the propagation time t1 is obtained from the time T1 to the Nth signal P2N and the average of the delay time τ. The propagation time in the reverse direction is likewise obtained, and the flow rate is calculated from them.
