A guide to understanding Air Thermal Mass Flow Meters:

Our principles of operation are as follows:

An air thermal mass flow meter measures the amount of heat dissipated by or absorbed by a heated sensor placed in the air stream. It changes the heat transfer characteristics of the sensor as more air passes through, allowing for more accurate flow measurements as the flow rate increases.

Parts and construction:

Temperature sensors, heated sensors, and control electronics are typically used in air thermal mass flow meters. As a result, the control electronics process the data and calculate the flow rate based on the temperature sensors. Sensors are usually thin films or wires, while temperature sensors monitor the temperature of the flowing air as well as the sensor.
