I. Product Overview

◆Thermal principle, fast response, high accuracy

◆Tubular shunt, not easy to block

◆Suitable for various low-pressure and high-pressure pipelines

◆Short preheating time, small zero drift, high reliability

◆Analog input/output can be used to control and display flow rate with a secondary instrument or flow computer

The ACU10FA mass flow controller consists of components such as a mass flow sensor, a laminar flow element, a flow controller regulating valve, and an amplification and control circuit. It is made using the thermal conductivity distribution effect that changes the temperature distribution of the measuring capillary wall by the heat transfer of the flowing fluid.

The ACU10FA uses the principle of calorimetry of the temperature difference before and after capillary heat transfer to measure the mass flow rate of gas, which is not affected 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, and the flow rate through the channel is closed-loop controlled to be equal to the set flow rate.
