Title: Vortex flowmeter
Inventor: ITO ICHIZO
IPC: G01F1/32
Filed: 1991-10-04
Abstract: PURPOSE:To obtain a vortex flowmeter free from the influence of leaking ultrasonic waves by only detecting and demodulating ultrasonic waves propagated through a fluid to be measured by utilizing the difference propagating time between the leaking ultrasonic waves and ultrasonic waves propagated through the fluid to be measured. CONSTITUTION:A pair of ultrasonic transmitter-receivers 4 and 5 send ultrasonic signals so that the signals can cross vortexes generated at a vortex generating body by a fluid to be measured flowing through a conduit and receive the signals. An oscillating means 10 sends an oscillating signal having an oscillating period which is sufficiently shorter than the generating period of the vortexes. A timing control means 11 impresses the oscillating signal upon the transmitter-receiver 4 as the above-mentioned ultrasonic signal which turns on the transmitter-receiver 4 for a prescribed period of time and performs control so that a wave receiving signal from the transmitter-receiver 5 can be turned off during the propagating time of leaking ultrasonic waves propagated through the conduit. A demodulating means 15 demodulates an added signal which is generated by adding the wave receiving signal and oscillating signal to each other by using the oscillating signal as a reference signal and outputs the added signal as a demodulated signal. A low-pass filter 16 having a sufficiently long time constant outputs the demodulated signal as a vortex signal after smoothing the demodulated signal.
