Thermal mass flowmeter adopts the principle of thermal diffusion, and thermal diffusion technology is a technology with excellent performance and high reliability under harsh conditions. Typical sensing elements include two thermal resistors (platinum RTDS), a speed sensor and a temperature sensor that automatically compensates for changes in gas temperature. When two RTDS are placed in a medium, where the velocity sensor is heated to a constant temperature above the ambient temperature, the other temperature sensor is used to sense the medium temperature. The mass flow of gas through the velocity sensor is calculated by the heat transfer of the sensing element. As the gas flow rate increases, the heat carried away by the medium increases. The temperature of the sensor decreases accordingly. In order to maintain a constant temperature, the working current through the sensor must be increased, and the increased part of the current is proportional to the flow rate of the medium. ● Thermal gas mass flowmeter can be used for gas flow measurement, and can also be used in the field of pass process control. ● Without temperature and pressure compensation, directly measure the mass flow rate of the fluid. ● No moving parts; Low pressure loss. ● Wide range ratio, high precision, high reliability. ● Simple installation, easy operation. ● Complete replacement of orifice plates and differential pressure flowmeters in all fields ● Combustion gas measurement in large combustion furnaces, co-production and other combustion processes ● Air aeration in sewage treatment, Digester and chlorine gas measurement ● Process gas and flare gas measurement in chemical and petrochemical plants ● Liquid gas, biogas, biogas measurement ● Coke oven gas measurement in coking plants, blast furnace gas measurement in ironmaking plants ● Primary and secondary air measurement in blast furnaces in power plants
