1. Types and principles of flow meters

The types and principles of flow meters are as follows: Type of flow meter: positive displacement flow meter: also known as fixed displacement flow meter. It uses mechanical measuring elements to continuously divide the fluid into individual known volume parts, and the total volume of the fluid is obtained by measuring the number of times the fluid in these volume parts is measured. Differential pressure flowmeter: The flow rate is calculated based on the differential pressure generated by the flow detection component installed in the pipeline, as well as the known fluid conditions and the geometric dimensions of the detection component and the pipeline. Float flowmeter: also known as rotor flowmeter, belongs to variable area flowmeter. Measure the flow rate by measuring the position of the float freely rising and falling inside a vertical cone tube that expands from bottom to top. Turbine flowmeter: The main type of velocity flowmeter, which uses a multi blade rotor to sense the average flow velocity of the fluid and derive the flow rate or total amount. Electromagnetic flowmeter: not directly mentioned, but it is based on Faradays law of electromagnetic induction for flow measurement, which measures the induced potential generated by the cutting magnetic field lines of a conductive fluid in a magnetic field to derive the flow rate. Fluid oscillation flowmeter: It uses the principle of fluid vibration under specific flow channel conditions to measure flow rate. Vortex flowmeter is one of them, which measures flow rate by exciting vortex vibration through fluid. Quality flowmeter: Yu Luan directly measures the mass flow rate of the fluid passing through the flowmeter, rat

her than the volume flow rate. Insertion flowmeter and probe flowmeter: These two types of flowmeters typically measure fluid flow in pipelines directly through insertion or probe. The principle of flowmeter: Volumetric flowmeter: divides the fluid into individual known volume parts through mechanical measuring elements, and counts the number of these parts to obtain the total flow rate. Differential pressure flowmeter: uses the pressure difference generated by fluid flow in a pipeline, combined with fluid properties and pipeline geometry to calculate flow rate. Float flowmeter: It measures flow rate based on the position of the float that freely rises and falls within the cone tube as the flow velocity changes, and belongs to variable area measurement. Turbine flowmeter: It derives flow rate by measuring the speed at which the fluid drives the turbine to rotate, and belongs to velocity based measurement. The above description of the types and principles of flow meters covers common types of flow meters and their working principles, each with its specific application scenarios and advantages.

2. What are the common types of flow meters (with applicable scope)? The common types and applications of flow meters are as follows: Electromagnetic flow meters work based on Faradays law of electromagnetic induction. Scope of application: Mainly used in sewage treatment. Working principle of elliptical gear flowmeter: When the measured liquid enters the flowmeter through the pipeline, the pressure difference generated at the inlet and outlet drives a pair of gears to rotate continuously, continuously conveying the liquid measured by the initial lunar cavity to the outlet. The product of the number of revolutions of the ell
