1. What are the types of flow meters?
There are two commonly used classification methods:
1. Classification according to measurement principles Principles of Li Zheng Socks Blind Learning: including coarse front chaotic differential pressure, rotor type, impulse type, movable tube type, direct mass type, target type, turbine type, vortex type, pitot tube type, as well as volumetric and weir rock barrier, groove type and other instruments
2. Electrical Principles: including electromagnetic, differential capacitive, inductive, strain resistance and other instruments
3. Acoustic Principles: such as ultrasonic, acoustic (shock wave), etc.
4. Thermal Principles: including thermal, direct calorimetry, indirect calorimetry, etc.
5. Optical Principles: such as laser, photoelectric, etc.
6. Other principles: including tracer principle (nuclear magnetic resonance principle), related principles, etc.
2. Classification based on the structural principle of flow meters According to the actual situation of current flow meter products, Ziyou Instruments can be roughly classified into the following types based on the structural principle of flow meters
1. Volumetric flow meters: suitable for measuring high viscosity, low Reynolds number fluids
2. Wheeled flow meters: such as water meters and turbine flow meters, the structure can be mechanical transmission output type or electric pulse output type
3. Differential pressure flow meters (pressure drop flow meters): composed of flow measuring elements and display instruments
4. Ultrasonic flow meters: based on the geometry and principles of the speed of ultrasonic waves propagating in the flowing medium, the averag
2. Doppler flowmeter
3. [Knowledge sharing of Mismi mechanical equipment] - Classification and working principle of flowmeter types
Classification and working principle of flowmeter types A flowmeter is an instrument used to accurately measure the total flow rate of fluid mechanics in pipelines or irrigation channels.. According to different classification criteria, flow meters can be classified into multiple types, and the working principle of each type is also different.
1. Classification of flow meters by measuring medium. Liquid flow meter: an instrument specifically used for measuring liquid flow rate.
. Gas flowmeter: a specialized instrument used to measure gas flow, capable of accurately measuring various gases such as liquefied gas, nitrogen, acetylene gas, etc. Classification by measurement principle: Mechanical principle: Differential pressure flowmeter: Using Bernoullis theorem, the flow rate is calculated by measuring the pressure difference generated by the flow detection component in the pipeline. Rotary flowmeter (also known as float flowmeter): Based on the principle of throttling, the flow rate is measured by changing the flow area of the fluid to maintain stable upper and lower pressure on the rotor. Impulse flowmeter and dynamic tube flowmeter: made based on the momentum theorem. Direct mass flowmeter: using Newtons second law to directly measure fluid mass
