Corrosion Resistant Thermal Gas Mass Flow Meter

The thermal gas mass flow meter is mainly composed of sensors, signal converters and display units. The following is a detailed introduction:SensorMeasuring probe: This is the core component, usually composed of two thermal resistance wires, one as a heating element and the other as a temperature measuring element. When gas flows through, the heat generated by the heating element will be taken away by the gas, resulting in temperature changes. The mass flow of the gas is calculated by measuring the temperature difference between the two thermal resistance wires. In order to accurately measure, the measuring probe generally uses high temperature resistant and corrosion resistant materials, such as platinum, rhodium and other metal alloys. Temperature compensation element: Since the thermal conductivity of the gas is related to temperature, in order to improve the measurement accuracy, a temperature compensation element will be set. It can measure the temperature of the gas in real time…
