Working principle
The flowmeter adopts the internationally leading CMOSens technology MEMS thermal gas flow sensor as the gas flow detection element. As shown in the figure, the sensor includes a micro heater and a pair of symmetrically distributed upstream and downstream temperature sensors. At zero flow rate, the two temperature sensors are in the same temperature field. When gas flows through, the temperature sensor detects a change in the temperature field, which corresponds to the flow rate.
