Flow is one of the four important process parameters
Closed pipeline flowmeter and technology classification
1.Differential pressure flowmeter
This is the most common traffic technology. Flow meters can be used to measure the flow rate of most liquids, gases, and vapors.
As the fluid flows through the turbine flow meter, the fluid rotates the rotor. The speed of full-time rotation is related to the speed of the fluid. The average velocity of the fluid felt by the rotor is pushed to the outflow or total volume. Turbine flow meter for accurate and precise measurement of clean liquids and gases
When a conductive fluid flows through an electromagnetic field, the velocity of the fluid can be obtained by measuring the voltage. The electromagnetic flowmeter has no moving parts and is not affected by the fluid. Highly accurate measurement of conductive liquids when full. Magnetic flowmeter can be used to measure the flow rate of slurry fluid
4. Ultrasonic flowmeter
The propagation time method and the Doppler effect method are commonly used in ultrasonic flowmeters to measure the average velocity of a fluid.
A vortex flowmeter is a non-streamline vortex generator placed in the fluid. The velocity of the vortex is proportional to the velocity of the fluid, so that the volume flow is calculated
Vortex flowmeter is mainly used to measure the flow of medium fluid in industrial pipelines
It is mainly used to replace differential pressure flow meters. This flow meter can be used to measure clean, low viscosity, medium and high speed fluid flow
