1. What are the types of flow meters? There are 8 types of flow meters, including differential pressure flow meter, volumetric flow meter, turbine flow meter, electromagnetic flow meter, ultrasonic flow meter, vortex flow meter, thermal mass flow meter, and Coriolis mass flow meter.

1、 Differential pressure flowmeter is the most common flow technology, including orifice plate, Venturi tube, and sonic nozzle. DP flow meters can be used to measure the flow rates of most liquids, gases, and vapors. The DP flowmeter has no moving parts and is widely used and easy to use. But after blockage, it will cause pressure loss, affecting accuracy. The accuracy of flow measurement depends on the accuracy of the pressure gauge.

2、 A volumetric flowmeter is used to measure the volumetric flow rate of liquids or gases. It introduces the fluid into the measuring space and calculates the number of rotations. Impellers, gears, pistons, or orifice plates are used to divert fluid. PD flowmeter has high accuracy and is one of the methods for measuring viscous liquids. But it can also generate irreparable pressure errors and require the installation of moving parts.

3、 Turbine flowmeter: When fluid flows through the turbine flowmeter, the fluid causes the rotor to rotate, and the rotational speed of the rotor is related to the velocity of the fluid. Derive the flow rate or total amount based on the average fluid velocity sensed by the rotor. Turbine flow meters can accurately measure clean liquids and gases. Like PD flow meters, turbine flow meters can also generate irreparable pressure errors and require moving parts.

4、 Electromagnetic Flowmeters (EMF) are a new type of flow measurement instrument that rapidly

developed in the 1950s and 1960s with the advancement of electronic technology. An electromagnetic flowmeter is an instrument that uses the principle of electromagnetic induction to measure the flow rate of a conductive fluid based on the induced electromotive force when the fluid passes through an external magnetic field.

5、 The propagation time method and Doppler effect method are commonly used in ultrasonic flowmeters to measure the average velocity of fluids. Like other speedometers, it is an instrument for measuring volumetric flow rate. It is an unobstructed flow meter, and if the ultrasonic transmitter is installed outside the pipeline for measurement, there is no need to insert it. It is suitable for almost all liquids, including slurries, with high accuracy, but the contamination of pipelines can affect the accuracy of precision monitoring.

6、 Vortex flowmeter is a volumetric flowmeter developed and produced based on the Karman vortex principle to measure the volumetric flow rate, standard condition volumetric flow rate, or mass flow rate of gases, vapors, or liquids. Mainly used for flow measurement of industrial pipeline media fluids, such as gases, liquids, steam, and other media.

7、 Thermal mass flowmeter is a flow meter that measures fluid mass flow rate by utilizing the temperature field changes generated when fluid flows through a pipeline heated by an external heat source, or by measuring the energy required for fluid temperature to rise by a certain value and the fluid mass when heating the fluid.

8、 Coriolis Mass Flowmeter, abbreviated as Coriolis force flowmeter, is a device that directly measures mass flow by utilizing the principle of Coriolis force proportional to the ma
