I. Product Overview

◆Thermal principle, higher accuracy, faster response, with network port

◆Tubular flow path, 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

ACU20FD High-Precision Mass Flow Meter/Flow Controller It adopts the principle of capillary heat transfer method 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.
