Summary
A thermal mass flow controller is a flow measurement device widely used in the chemical, petroleum, and food industries. Its operating principle is based on the thermal diffusion effect, calculating the fluid flow rate by heating a sensing element and measuring the fluid's cooling effect on it. Thermal mass flow controllers typically consist of a heating coil and two temperature sensors.
During operation, the heating coil heats the fluid in the pipe, and the temperature sensor measures the fluid's temperature. When the fluid flows through the heating coil, it carries away heat, causing a temperature drop measured by the sensor. The fluid flow rate can be calculated based on the rate at which the fluid cools the heating coil. The thermal mass flow controller can process the data using a microprocessor and output an accurate flow rate value.
Thermal mass flow controllers have the advantages of fast response, high accuracy, and resistance to the influence of pressure and humidity, making them suitable for measuring the flow rate of liquids and gases. Many professional thermal mass flow controller manufacturers offer a variety of models and specifications to meet the needs of different industries.
In summary, the thermal mass flow controller is a reliable and accurate flow measurement device. Its operating principle is based on the thermal diffusion effect, achieving flow measurement by heating and measuring the fluid temperature. With the development of industrial automation, the application range of thermal mass flow controllers will continue to expand, providing more reliable flow control assurance for the production process.
