Ultrasonic flowmeter is a common non-contact flowmeter. It measures the speed and flow of moving material by sending high-frequency sound waves. When sound waves pass through a fluid, the frequency and amplitude of the sound waves also change due to changes in the speed of sound, so the flow rate of the fluid can be calculated by measuring these changes.
While ultrasonic flowmeters can measure almost any fluid, they cannot measure colloids. The reason is that the ultrasonic wave will be scattered, reflected and absorbed when passing through the colloid, resulting in inaccurate measurement. In addition, the physical properties of the colloid, such as viscosity and turbidity, can also cause changes in the propagation of sound waves, which can affect the measurement results.
