What is a thermal mass flow meter?
Thermal mass flowmeter is an accurate, easy-to-install, low pressure drop type flowmeter. It is suitable for flow measurement and control of dry gas applications. Thermal mass flow meters are also available through the Gas Type Reference link application. The mass flow meter observes the cooling effect on the heated transducer as the air flow changes. Compared to other gas flow measurement equipment, the result is a high level of accuracy at a low cost.

Thermal mass flow meter principle
Thermal mass flow meters use the thermal properties of a fluid to measure the motion of the fluid in a pipe or tube. In a thermal energy flow meter, the measured heat is applied to the heater of the sensor. A certain amount of energy is lost during the flow, and as the flow increases, more energy is lost. The energy lost by the sensor depends on the thermal characteristics of the fluid and the sensor design. The hot-pressing characteristics of a fluid may change with temperature and pressure, although these changes are usually irrelevant in most applications. Since heat flow measurement does not depend on the temperature or pressure of the fluid, a thermal energy flow meter can be used to estimate the mass flow of the fluid.
In other words, in most applications, the nature of a fluid may depend on its composition. For these applications, different components of the fluid may interfere with the heat flow size during actual operation. Therefore, it is important for a thermal mass flow meter provider to understand the composition of the fluid so that the appropriate normalization factors can be processed to accurately determine the flow. Due to this limitation, thermal mass flow meters are often used to measure the flow of pure gases. Manufacturers can provide appropriate standardized information for other gas combinations, but the accuracy of a thermal mass flow meter depends on whether the actual gas mixture is the same as the gas mixture used for standardization purposes.
