1. What are the types of flow meters?
There are mainly the following types of flow meters.
1. Definition of mass flow meter: It measures the mass flow rate of a fluid based on the thermodynamic properties and measurement principles of the substance.. Classification: It can be divided into two types: thermal and thermosensitive. This type of flowmeter can directly measure the mass flow rate of fluids, without being affected by changes in fluid density, temperature, pressure, etc.
2. Definition of volumetric flowmeter: It measures the volumetric flow rate of fluids based on the volume or volume of fluid flowing through the sensor. Classification: including volumetric flow meters and vortex flow meters, etc. This type of flowmeter calculates flow rate by measuring the volume of fluid flowing through it over a certain period of time. Definition of differential pressure flowmeter: It uses the pressure difference of fluid in a pipeline to calculate flow rate. Categories: including orifice flow meters, nozzle flow meters, float flow meters, etc. This type of flowmeter calculates flow rate by measuring the pressure difference generated by the fluid in the pipeline.
4. Definition of vortex flowmeter: It measures flow rate by using the pressure pulsation generated by the vortex street rotating in the fluid.
. Applicable occasions: Suitable for industrial occasions with high flow rates. This type of flowmeter measures flow rate by detecting the rotational frequency of vortex streets in the fluid. Definition of magnetic flowmeter: Based on Faradays electromagnetic induction principle, Tonghuai Chunxian calculates flow rate by measuring the conductivity and magnetic induction intensity in the flui
6. Definition of ultrasonic flowmeter: It measures the flow rate by using the change in sound velocity when ultrasonic waves pass through the fluid.
. Applicable object: It is suitable for measuring liquids with high viscosity, high solid particles or foam. This type of flowmeter calculates the flow rate by measuring the changes in the propagation speed of ultrasonic waves in the fluid.2. What are the types of flow meters?
There are many types of flow meters, and according to the most popular and widely used classification method, they can be mainly divided into the following categories
1. The principle of volumetric flow meters is to measure the flow rate by measuring the volume of fluid introduced into the measuring space and calculating the number of rotations.
. Features: High accuracy, suitable for measuring viscous liquids. But it will generate irreparable pressure errors and require the installation of moving parts. 2. Differential pressure flowmeter principle: It measures flow rate by using the pressure difference generated when the fluid passes through a throttling device (such as orifice plate, Venturi tube, etc.). Features: Widely applicable, easy to use, no moving parts. But it will result in pressure loss, affecting accuracy, and the accuracy of flow measurement depends on the accuracy of the pressure gauge.3. Principle of float flowmeter: Flow is measured by the buoyancy effect of the fluid on the float.
. Features: Simpl
