thermal mass flow meter working principle
The working principle of thermal mass flowmeters (TMF) is mainly based on the heat exchange relationship between the fluid and the heat source to measure the mass flow of the fluid. Specifically, its working principle can be divided into the following aspects:
Basic principle
The thermal mass flowmeter measures the mass flow of the fluid by using the temperature field change generated when the fluid passes through the external heat source to heat the pipeline, or by the relationship between the energy required for the fluid temperature to rise and the mass of the fluid when the fluid is heated. This flowmeter is mainly used to measure the mass flow of gas and is popular for its high accuracy, high repeatability and high reliability.
Specific implementation method
The thermal mass flowmeter usually contains two key

Coriolis flow meter (also known as Coriolis flowmeter) is an instrument that uses the Coriolis force effect generated when the fluid flows in a vibrating tube to measure fluid mass flow. This type of flow meter has a wide range of applications in many fields. The advantages and disadvantages of Coriolis flow meters are detailed below:
Advantage:
High-precision measurement: Coriolis mass flow meters can provide high-precision mass flow measurement, which is especially important for
processes that require precise control of fluid flow. Its accuracy is generally higher than many other types of flow meters.
Direct measurement of mass flow: Coriolis flow meters
