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.

ACU10FDR


The ACU10FDR low differential pressure gas mass flow controller, equipped with a proprietary high-flow electromagnetic valve, is suitable for controlling mass flow in situations with minimal available system pressure. The low differential pressure ensures minimal impact on the system, enabling flow control under near-atmospheric pressure conditions and reducing system response time. We will customize the valve and PID control functions for you based on your application parameters to ensure that the product can achieve fast and stable control while maintaining low pressure loss.

ACU10FC


The ACU10FC differential pressure mass flow controller uses a differential pressure mass measurement principle with no thermal drift and no response lag. It can simultaneously display and output: instantaneous flow rate, cumulative flow rate, pressure, temperature, etc. When a control function is required, an electromagnetic proportional control valve and built-in PID control function can be added. Unlike thermal flow meters, the ACU10FC has no additional "specific heat capacity" error when using gas conversion coefficients. Therefore, even if the measured gas is different from the calibration gas at the factory, it will not affect the measurement accuracy.

ACU10P


The ACU10P series pressure controllers/gauges feature a straight-through design with a measurement range from 100 kPa to 10 MPa (both absolute and gauge pressure). Differential pressure transmitters are also available.
