The so-called two-channel ultrasonic flowmeter is actually equivalent to two ultrasonic flowmeters connected in parallel to measure the flow rate of fluid passing through a pipe section in a unit time, and then comparing and neutralizing the two data to obtain measurement data.


The two-channel ultrasonic flowmeter not only overcomes the defect that the monophonic ultrasonic flowmeter is not suitable for the change of flow field and has low accuracy and unstable flow rate, but also the measurement principle is still based on the time delay method. Due to the optimized design of two channels, it overcomes the influence of turbulence randomness on measurement to a large extent, greatly improves the adaptability to different working conditions and ensures the measurement accuracy. The small flow rate measurement by the ultrasonic flowmeter is more reliable.  It can be used as a measurement standard for quantitative control.  It is especially suitable for flow measurement of high viscosity oils, chemical products and ultra-pure water.


Flow measurement is an important guarantee for the quality of industrial production. It is also an important parameter in the industrial production process of steel, electricity, chemical industry, medicine, food and so on.  The level of flow supervision and control is directly related to the production quality, production efficiency, full use of energy, control of product costs, and economic accounting of production departments.  Therefore, for the flow meters used for monitoring, the stability and quality requirements become the top priority.
