The working principle of the thermal gas mass flowmeter is based on King's Law. The core idea is to directly calculate the mass flow rate of the gas by measuring the heat carried away by the gas as it flows through the sensor. The display direction can be reversed 180°, making it easy to set and view the color crystal display. The cumulative flow data is clear at a glance and monitored in real time.
