ACU10FA Series
The ACU10FA analog mass flow controller features fast response and high accuracy. It offers a wide control range, from 5 SCCM to 30 SLM, and can measure and regulate flow rates as low as 1 SCCM, making it suitable for controlling very small flow rates.
Range: 0-300SLM

◆ Thermal principle, fast response, high accuracy
◆ Tubular shunt, less prone to blockage
◆ Suitable for various low-pressure and high-pressure pipelines
◆ Short warm-up time, minimal zero drift, and high reliability
◆ Analog inputs/outputs can use secondary instruments or flow computers to control and display flow rates.
The ACU10FA mass flow controller consists of a mass flow sensor, a laminar flow element, a flow‑control regulating valve, and an amplification control circuit. It operates on the principle of heat conduction, which alters the temperature distribution along the wall of a measurement capillary as the flowing fluid transfers heat.
The ACU10FA measures gas mass flow using the capillary‑based differential‑temperature calorimetric principle, which is unaffected by temperature and pressure. The flow signal detected by the sensor is amplified and compared with a setpoint voltage; the resulting error signal drives a control valve, enabling closed‑loop regulation of the flow through the channel to match the desired setpoint.
