Types of flow meters and their advantages and disadvantages

Summary of differential pressure flow meters (DP flow meters) Principle: Based on the pressure sensitive obstruction generated when fluid flows through throttling devices (such as orifice plates, Venturi tubes, sonic nozzles), flow velocity is measured.

. Advantages: No moving parts, simple structure, wide application, suitable for measuring liquids, gases, and vapors. Disadvantage: Large pressure loss after blockage, affecting accuracy; The measurement accuracy depends on the precision of the pressure gauge. The principle of a volumetric flowmeter (PD flowmeter) is to calculate the volumetric flow rate of the casing by measuring the volume of space occupied by the fluid (such as the number of rotations of the impeller, gear, and piston). Advantages: High precision, especially suitable for measuring viscous liquids. Disadvantage: It generates irreparable pressure errors, requires moving parts, and may wear out over long-term use. Principle of turbine flowmeter: The fluid drives the rotor to rotate, and the rotor speed is proportional to the fluid flow rate. The flow rate is derived by detecting the speed. Advantage: Suitable for high-precision measurement of bridge blockage in clean liquids and gases. Disadvantage: It generates irreparable pressure errors, requires moving parts, and has high requirements for fluid cleanliness. Principle of electromagnetic flowmeter: Based on Faradays law of electromagnetic induction, a conductive fluid moves in a magnetic field to generate an induced potential, and the flow velocity is calculated by measuring the voltage. Advantages: No moving parts, not affected by fluid density and viscosity, high accuracy in measuring conductive liquids when the tube is full, suitable for slurry f
