Introduction to the classification of flow meters

Classified according to measurement principles:
1. Various principles of physics serve as the theoretical foundation for flow measurement, and flow principles can be classified according to physics
a. Principles of mechanics
b. Principles of Thermotics
c. Acoustic principle
d. Optical principle
e. Principles of atomic physics
2. Classification based on measurement principles and structures
Flow meters can be classified into eight categories based on their measurement methods, namely: velocity-based flow meters (such as vortex street flow meters, vortex precession flow meters, turbine flow meters, ultrasonic flow meters, etc.); differential pressure flow meters (orifice flow meters, V-cone flow meters, etc.); volumetric flow meters (elliptic gear flow meters, roots flow meters, diaphragm gas meters, etc.); mass flow meters (Coriolis mass flow meters, calorimetric gas mass flow meters, etc.); and open channel flow meters (Parshall flume, triangular weir, etc.).
The above is just an introduction to the classification of flow meters based on their working principles and product structures. Each type of flowmeter has its own unique product structure and working principle. When communicating about flowmeter technology with on-site personnel, it is necessary to determine the temperature, pressure, flow rate, and properties of the measured medium.
