Thermal gas mass flow meter is a gas flow measurement instrument based on the principle of thermal diffusion. It does not require temperature and pressure compensation and directly measures the mass flow rate of the fluid. Its prominent feature is that it can directly conduct trade settlement; No moving parts; Low pressure loss; Wide range ratio; High precision; High reliability; Easy to install and operate. Widely used in industries such as petroleum, chemical, medical, thermal power plants, and environmental protection.
