A thermal mass flow meter is a sensor that calculates flow rate by detecting changes in the temperature of the fluid, and consists mainly of two parts: a heater and a pyrometer. During the measurement process, the heater heats the fluid and increases its temperature, and the pyrometer measures the difference between the fluid temperature and the pre-heating temperature and uses this to estimate the flow rate.
Thermal mass flow meters have certain advantages and disadvantages, and their application scope and specific conditions need to be evaluated according to the actual situation. In practical applications, the appropriate type and specification of flowmeter should be selected to ensure the accuracy and reliability of the measurement results.
