2. Principle and advantages of HSC series ultrasonic flowmeter

HSC series ultrasonic flowmeter is based on the principle of ultrasonic wave propagation time difference to achieve flow measurement, with significant advantages such as high accuracy, no pressure loss, and strong adaptability.The sentence is:.

1. Working Principle The core principle of HSC series ultrasonic flowmeter is based on th

e ultrasonic propagation time difference method: Basic theory: the propagation speed of ultrasonic waves in a flowing medium is equal to the vector sum of the average flow velocity of the measured medium and the velocity of sound waves in a stationary medium.

. When an ultrasonic beam propagates in a liquid, the flow of the liquid causes a slight change in propagation time, and the change in propagation time is proportional to the flow velocity of the liquid. Specific process: When there is zero flow, the time required for two sensors to emit and receive sound waves is exactly the same, which is the only technology that can actually measure zero flow. When the medium flows, the transmission time of sound waves in the upstream direction is greater than that in the downstream direction. By measuring the time difference between forward and backward propagation, combined with the vector relationship between sound velocity and medium flow velocity, the average flow velocity of the fluid can be accurately calculated, and the flow rate value can be obtained. Secondly, the HSC series ultrasonic flowmeter has strong anti-interference ability and high measurement accuracy: it is not affected by changes in fluid density, viscosity, temperature, pressure, and conductivity, and the linear measurement principle ensures high-precision measurement. All digital processing technology enables fast computation speed, strong anti-interference ability, reliable measurement, and high accuracy, with a measurable range of up to 1:150. No pressure loss, energy-saving and environmentally friendly: There is no obstruction or moving parts inside the measuring tube, which will not cause additional energy loss or blockage problems.
