Abstract

The invention discloses a measurement system for the average fluid flow velocity on a straight line distance, which includes a controller, a motor, ultrasonic receiving terminals A and B, an ultrasonic transmitting terminal C, and a photoelectric receiving terminal A ， and B ， , photoelectric transmitter C ， ; The ultrasonic receiving end A and the photoelectric receiving end A ， placed in the same position; the ultrasonic receiving end B and the photoelectric receiving end B ， placed in the same position; the ultrasonic transmitter C and the photoelectric transmitter C ， Placed at the same position for signal generation and transmission; the positions of ultrasonic receiving end A and ultrasonic receiving end B are fixed, located at the same end of the measurement, and on the same horizontal straight line, where ultrasonic receiving end A and ultrasonic emitting end C are located The straight line AC is always perpendicular to the fluid velocity v, ∠CAB=90°, point C can move freely on the straight line where AC is located. The invention not only has simple structure and strong practicability, but also has high measurement precision of fluid flow velocity.

Description

technical field [0001] The invention relates to a measuring system for the average fluid flow velocity on a straight line distance. Background technique [0002] Fluid flow has always been a hot research direction. With the increasing maturity of chip technology, digital signal processing technology, image processing technology and computer technology, fluid flow velocity measurement technology has also been developed. Flow detection instruments and systems have been widely used in technical departments such as cement, chemical industry, textile, medicine, papermaking, water supply and drainage, food and beverage, etc. All aspects have put forward higher and higher requirements for automatic detection technology. Performance, quality and reliability directly affect the economic benefits of the enterprise. However, the accompanying problem of fluid sewage discharge has become an important task for relevant government functional departments. The flow meter system for measurin...
