EtherCAT protocol
The ACU20FD digital mass flow meter consists of a mass flow sensor, a laminar flow element, a flow control valve, and an amplification and control circuit. It uses digital signal input and output and features a short preheating time, small zero drift, and high reliability.

◆ 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 using a secondary meter or flow computer
The ACU20FD high-precision 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 to close-loop control the flow rate through the channel so that it is equal to the set flow rate.
