ACU20FDL
The ACU20FDL liquid mass flow controller consists of components such as a mass flow sensor, a flow control valve, and an amplifier control circuit. It is made using the heat transfer distribution effect that changes the temperature distribution of the measuring capillary wall by the heat transfer of the flowing fluid. A customized high-speed proportional control valve is used to precisely control the liquid volume flow/mass flow.

I. Product Overview
◆ Thermal principle, higher accuracy, faster response, with network port
◆ Tubular flow distribution, 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 secondary instruments or flow computers
The ACU20FDL high-precision liquid mass flow meter/flow controller 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 obtained difference is used to drive the control regulating valve, and the closed-loop control of the flow rate through the channel makes it equal to the set flow rate.
