I. Product Overview

◆ Thermal principle, fast response, high accuracy

◆ Tubular flow divider, not easy to block

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

◆ Short preheating time, small zero drift, high reliability

◆ Digital input/output can be used to control and display flow rate with secondary meters or flow computers

The ACU10FD mass flow controller consists of a mass flow sensor, a laminar flow divider, a flow controller regulating valve, and an amplifier control circuit. It is made using the effect of heat conduction distribution where the heat transfer of the flowing fluid changes the temperature distribution of the measuring capillary wall.

The ACU10FD mass 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, 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 rate through the channel to equal the set flow rate.
