Product Description
RF3700 thermal gas mass Flowmeter is based on the principle that the speed of heat absorption is directly related to mass. The sensor of the instrument is composed of two reference grade thermal resistance (platinum RTD).
One is the mass velocity sensor T 1, the other is the temperature sensor T 2, which measures the change of gas temperature. When the two TRD are placed in the measured gas, the sensor T1 is heated to a constant temperature difference above the gas temperature, and the other sensor T2 is used to induce the measured gas temperature. With the increase of gas mass velocity, the air flow takes away more heat, according to the King's law of thermal effect. When moving gas molecules hit thermoelectric resistance,
The larger the flow rate is, the more molecules are exposed to the thermal resistance, and the more heat is absorbed. The thermal absorption is related to the number of molecules, thermal properties and flow characteristics of a certain gas. It is widely used in petroleum, chemical industry, metallurgy, scientific research and other fields.
