Product Description
Thermal gas mass flow meter
Overview
The thermal gas mass flow meter is designed based on the principle of thermal diffusion, which uses the constant temperature difference method to accurately measure the gas. The utility model has the advantages of small volume, high digitization degree, convenient installation and accurate measurement.
The sensor part consists of two reference grade platinum resistance temperature sensors. When the instrument is working, one sensor continuously measures the medium temperature T1; the other sensor self-heats to the medium temperature T2, which is used to sense the fluid flow rate, called the speed. sensor. The temperature ΔT=T2-T1, T2>T1, when there is fluid flowing, the gas molecules collide with the sensor and take away the heat of T2, so that the temperature of T2 is lowered. To keep ΔT unchanged, it is necessary to increase T2. The supply current, the faster the gas flow rate, the more heat is removed, and the gas flow rate and the added heat have a fixed function relationship. This is the principle of constant temperature difference.
