CXMF thermal Gas Mass Flowmeter is a kind of flowmeter that measuring the flow mass to gain related data.
The Thermal Gas Mass Flowmeter is designed based on the principle of thermal diffusion.
The Thermal Gas Mass Flowmeter uses the constant temperature difference method to accurately measure gas. Thermal Gas Mass Flowmeter has the advantages of small size, high digitization, easy installation and accurate measurement.
The sensor part of the Thermal Gas Mass Flowmeter is composed of two reference level platinum resistance temperature sensors.
When the Thermal Gas Mass Flowmeter is working, one sensor can continuously measure the medium temperature T1;
the other sensor’s temperature rises to higher than the medium temperature T2 through self-heating, it is used to sense the flow rate of the fluid, so it’s known as velocity sensor.
The temperature △ T =T2-T1, T2˃T1, when there is a fluid flowing, gas molecules collide with the sensor and take away the heat of T2, which makes the temperature of T2 reduction. If to keep △ T unchanged, it is necessary to increase the supply current of T2.
The faster the gas flows, the more heat will be taken away.
There is a fixed functional relationship between gas flow velocity and incremental heat, which is the principle of constant temperature difference.
