Working principle and advantages of mass flow controllers
 
1、 Mass flow controller It usually consists of a circuit board, sensor, inlet and outlet pipe fittings, a flow divider pipe, a casing, a regulating valve, and other components. Its operating power supply, flow display, and setting operations are provided by the matching flow display power supply.
 
2、Mass flow controllers can be used to control various clean and dry gases, including corrosive and special gases. However, for corrosive and special gases, appropriate models and sealing materials must be selected.
 
3、Mass flow controllers are a new type of flow metering and monitoring instrument that can conveniently and accurately monitor various gases flowing in pipelines without temperature and pressure compensation.
 

4、Mass flow controllers use the thermal diffusion principle. Thermal diffusion technology is a technology with excellent performance and high reliability under harsh conditions.

 

5、Mass flow controllers are instruments that use the principle of heat conduction to measure fluid flow. Mass flow controllers use the constant temperature difference method to accurately measure gas mass flow. Mass flow controllers have advantages such as small size, high degree of digitalization, easy installation, and accurate measurement.

ACCU10FD Digital Mass Flow Controller/Flow Meter It consists of a mass flow sensor, a laminar flow element, a flow controller regulating valve, and an amplifier control circuit. It is made using the heat conduction distribution effect, where the heat transfer of the flowing fluid changes the temperature distribution of the measuring capillary wall.
 

ACCU10FD Digital Mass Flow Controller/Flow Meter It uses the principle of calorimetry of the temperature difference before and after capillary heat transfer to measure the mass flow rate of gas, unaffected by temperature and pressure. The flow signal measured by the sensor is amplified and then compared with the set voltage. The resulting difference is used to drive the control regulating valve, closing the loop to control the flow through the channel so that it is equal to the set flow.
