Title: Ultrasonic vortex flowmeter
Inventor: YOSHIKURA HIROSHI
IPC: G01F1/32
Filed: 1998-09-25
Abstract: PROBLEM TO BE SOLVED: To provide an ultrasonic vortex flowmeter with a simple structure which can perform stable and good flow rate measurement irrespective of a change in temperature of a fluid to be measured. SOLUTION: The ultrasonic vortex flowmeter comprises a comparator 6 for converting an ultrasonic reception signal D into a rectangular reception signal E based on a threshold for inputting into a phase comparator 7 and a phase difference monitor circuit 12 for changing the threshold of the comparator 6 based on a phase difference signal G from the phase comparator 7.  Since the threshold of the comparator 6 is changed based on the phase difference signal G with a temperature of a measured fluid reflected, and conversion timing of the ultrasonic reception signal D of the comparator 6 into the rectangular reception signal E can be changed according to the temperature of the measured fluid, the rectangular reception signal E can be in a demodulation range of the phase difference comparator 7, thereby allowing stable and good flow rate measurement to be done over a wide temperature range. Since good flow rate measurement over a wide temperature range can be done without using a phase shifter with a complicated structure, the constitution can be simplified and the apparatus can be reduced in cost.

Abstract: PURPOSE:To make it possible to measure a distance quickly with excellent precision by making a low-pass filter operate after a prescribed time from the start of emission of a modulation light to the input of a measured distance signal passes. CONSTITUTION:Based on an LCON signal from CPU B12, a light projection circuit B11 puts on and off a projector D1. An infrared modulation light is projected to an object of distance measurement, reflected therefrom diffusedly and sensed by PSD 17, and photocurrents 11 and 12 are outputted according to a position whereat the light is sensed. A light-sensing circuit B16 converts the currents 11 and 12 into voltage signals S1 and S2. A switch circuit SW1 makes switching as to which of the signals S1 and S2 is to be sent to an amplifier circuit B14, while ON/OFF of a switch circuit SW2 is controlled by a CCON signal of the CPU B12. The circuit SW2 turns ON after a prescribed delay time from putting-on of the projector D1 to the start of data input from the circuit 14 passes, and it turns OFF when putting-off of the projector D1 starts after the SW2 turns ON. Accordingly, accurate measurement of a distance is executed without being affected by a phase shift of the circuit B14.
