1. Types and principles of flow meters

1. Mechanical principles: Instruments belonging to this type of principle 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 and vortex street type utilizing the principle of fluid oscillation; Utilize pitot tube type, volumetric type, weir, trough type, etc. that utilize the total static pressure difference.

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 using thermal principles, such as calorimetry, direct calorimetry, indirect calorimetry, etc.

5、 Optical principles: Laser and photoelectric instruments belong to this type of principle.

6、 Based on physical principles, instruments such as nuclear magnetic resonance and nuclear radiation belong to this type of principle. Other principles include labeling principles (tracer principle, nuclear magnetic resonance principle), related principles, etc. Extended data flowmeter is one of the important instruments in industrial measurement. With the development of industrial production, the requirements for accuracy and range of flow measurement are becoming increasingly high, and flow measurement technology is advancing rapidly.

In order to adapt to various applications, various types of flowmeters have emerged one after another. There are currently over 100 types of flow meters in use. Each product has its specific applicability and limitations. According to measurement principles, there are mechanical principles, thermal principles, acoustic principles, electrical principles, optical principles, atomic physics principles, etc. Classify according to the structural principle of flow meters. There are volumetric flow meters, differential pressure flow meters, float flow meters, turbine flow meters, electromagnetic flow meters, vortex flow meters in fluid oscillation flow meters, mass flow meters, and insertion flow meters. According to the measurement object, there are two main categories: closed pipelines and open channels; According to the measurement purpose, it can be divided into total measurement and flow measurement, and their instruments are called total meter and flow meter respectively. A total flow meter measures the flow rate through a pipeline over a period of time, expressed as the quotient of the total amount flowing over a short period of time divided by that time. In fact, flow meters are usually equipped with cumulative flow devices for use as total flow meters, and total flow meters are also equipped with flow signaling devices. Therefore, dividing flow meters and total meters in a strict sense has no practical significance. Reference source: Baidu Baike - Flow Meter
