Ultrasonic flow meter is based on the principle of "velocity difference method" to measure the liquid flow in a circular tube. It adopts advanced multi-pulse technology, digital signal processing technology and error correction technology, so that the flow meter can adapt to the environment of the industrial site, and the measurement is more convenient, economical and accurate.
1. Ultrasonic flowmeter definition
Ultrasonic flowmeters are instruments that measure flow by detecting the effect of fluid flow on an ultrasonic beam (or ultrasonic pulse). ?
2. Ultrasonic flow meter signal detection principle
2.1 According to the principle of signal detection, ultrasonic flowmeters can be divided into propagation velocity difference method (direct time difference method, time difference method, phase difference method and frequency difference method), beam migration method, Doppler method, cross-correlation method, space filter method and noise method.
2.2 Ultrasonic flowmeter and electromagnetic flowmeter, because the instrument flow channel is not set up any obstruction, are non-obstruction flowmeter, is suitable for solving the flow measurement difficulties of a class of flowmeter, especially in the large flow measurement has a more prominent advantage, it is one of the rapidly developing class of flowmeter.
2.3 Ultrasonic flowmeter is an instrument that measures flow by detecting the effect of fluid flow on ultrasonic beam (or ultrasonic pulse).
3. Ultrasonic flowmeter test working principle
When the ultrasonic beam propagates in the liquid, the flow of the liquid will cause a small change in the propagation time, and the change in the propagation time is proportional to the flow rate of the liquid. At zero flow, the time required for the two sensors to transmit and receive sound waves is exactly the same (the only technology that can actually measure zero flow), and when the liquid flows, the transmission time of sound waves in the counter-current direction is greater than that in the forward direction.
Tubular ultrasonic flow meters are widely used in industrial departments such as petroleum, chemical, metallurgy, and various measuring stations and trade settlement centers to measure the flow rate or total amount of gas or liquid media.
