1. Doppler Ultrasonic Flow Meter

Doppler Ultrasonic Flow Meter is an instrument that uses the principle of Doppler effect for flow measurement. It is suitable for measuring the flow rate of fluids containing bubbles, solid particles, or other impurities, and is widely used for flow monitoring of fluids such as sewage, wastewater, and slurry, especially under harsh conditions, with significant advantages. For open channel flow measurement, this equipment is also known as Doppler ultrasonic open channel flowmeter. Its principle and application are similar to pipeline flowmeter, but it is specifically used for open channel flow. 2. Detailed explanation of the working principle of ultrasonic flowmeter: the measurement force of "invisible" sound waves is the most common measurement method. Principle description: Two ultrasonic sensors installed in the upstream and downstream directions of the pipeline, alternately emitting and receiving ultrasonic signals. When a liquid flows, the propagation speed of sound waves in the downstream direction will increase, while the propagation speed in the upstream direction will decrease. By comparing the "arrival time difference" between upstream and downstream, the flow velocity can be calculated. Calculation formula: Δ t=tup − down2 ∝ v \ Delta t=\ frac {t {up} - t {down}...

3. Measurement principle of ultrasonic flow meter

Ultrasonic flow meter is a non-contact flow measurement instrument that uses ultrasonic technology to measure the flow rate of liquids or gases. Ultrasonic flow meters have the advantages of high precision, no moving parts, easy installation, and convenient maintenance, and are widely used for measuring various fluid flow rates. Its basic working principle is to utilize the relationship between ultrasonic propagation speed and fluid flow velocity. one The working principle of ultrasonic flowmeter is mainly based on ..
