1. Types and principles of flow meters

According to the measurement principle, flow meters can be divided into the following categories:

1. Mechanical principles: Instruments belonging to this category include differential pressure type and rotor type using Bernoullis theorem; The impulse equation and movable tube equation using the momentum theorem; Using the direct mass formula of Newtons second law; Target based on the principle of fluid momentum; Turbine type using the angular momentum theorem; Vortex type, vortex street type, etc. utilizing the principle of fluid oscillation.

2、 Electrical principles: Instruments used for this type of principle include electromagnetic, differential capacitive, inductive, strain resistance, etc.

3、 Acoustic principles: There are ultrasonic and acoustic (shock wave) methods that use acoustic principles for flow measurement.

4、 Thermal principles: There are various methods for measuring flow rate using thermal principles, such as calorimetry, direct calorimetry, and indirect calorimetry.

5、 Optical principles: Instruments such as laser and photoelectric instruments belong to this type of principle.

6、 Atomic physics principles: Nuclear magnetic resonance, nuclear radiation, etc. are instruments belonging to this type of principle.

7. Other principles include labeling principles (tracer principle, nuclear magnetic resonance principle), related principles, etc. Extended Data Flow Meter Market Factor: Driving Factors According to the International Energy Agency (IEA) forecast, a cumulative global investment of $26.0 trillion (in 2007 US dollars) is needed in energy infrastructure from 2007 to 2030. In the long run, foreseeable ener

gy investment will bring considerable development space for the application of flow meters in the oil and gas and energy industries. Faced with a fierce competitive environment, in order to meet the global demand for energy conservation and emission reduction, electronic technology is being increasingly introduced into flow meters, which enables them to have self diagnostic functions and better communicate with production control levels. The improved performance and high brightness better meet the needs of industry users, creating more market application space for flow meters. Reference source: Baidu Baike - Flow Meter
