1. Inventory of types of flow meters

Flow meters are important instruments used in industrial measurement to measure fluid flow. With the development of industry, their types are becoming increasingly abundant. The following is an inventory of common types of flow meters: Differential pressure flow meters (DP) principle: based on the pressure difference generated by fluid flow, including orifice plates, Venturi tubes, and sonic nozzles. Features: No moving parts, widely used and easy to use; But after blockage, pressure loss will occur, affecting accuracy. The accuracy of flow measurement depends on the accuracy of the pressure gauge. Application: Can be used to measure the flow rate of most liquids, gases, and vapors. The principle of a volumetric flowmeter (PD) is to introduce a fluid into a measuring space, measure the volumetric flow rate of a liquid or gas by calculating the number of rotations, and use impellers, gears, pistons, or orifice plates to divert the fluid. Characteristics: High accuracy, it is one of the effective methods for measuring viscous liquids; But it will generate irreparable pressure errors and requires the installation of moving parts. Application: Suitable for measuring the volumetric flow rate of liquids or gases. Principle of turbine flowmeter: When fluid flows through, the rotor rotates, and the rotational speed of the rotor is related to the fluid velocity. The flow rate or total amount is derived from the average fluid velocity sensed by the rotor. Features: Can accurately measure clean liquids and gases; But it will generate irreparable pressure errors and also require moving parts. Application: Used to measure the flow rate of clean liquids and gases. Principle of electromag

netic flowmeter: According to Faradays law of electromagnetic induction, when a fluid with a conductive nanobridge flows through an electromagnetic field, the fluid velocity is obtained by measuring the voltage. Features: No moving parts, not affected by fluids, high accuracy in measuring conductive liquids when the tube is full, and can be used to measure the flow velocity of slurry fluids; The measurement system includes transmitters and sensors, with two models: integrated type (transmitter and sensor form an integrated mechanical unit) and separated type (transmitter and sensor are installed separately). Application: Suitable for measuring the flow rate of conductive liquids. Principle of ultrasonic flowmeter: The propagation time method and Doppler effect method are commonly used to measure the average velocity of the fluid, and then measure the volumetric flow rate. Features: It is an unobstructed flow meter. If the ultrasonic transmitter is installed on the outside of the pipeline, it does not need to be inserted; Suitable for almost all liquids, including slurries, with high accuracy; But the contamination of the pipeline can affect accuracy. Application: Used to measure the flow rate of various liquids. Principle of vortex flowmeter: A non streamlined vortex generator is placed in the fluid, and the velocity of the vortex is proportional to the fluid velocity, in order to calculate the volumetric flow rate. Features: No moving parts, no dirt issues; But it will generate noise and requires the fluid to have a high flow velocity to generate vortices. Application: Suitable for measuring the flow rate of liquids, gases, or vapors. The principle of thermal mass flowmeter is to measure the fluid velocity by measuring
