ACU20FD Normally Open Valve Series

◆ Thermal‑anemometer principle, offering higher accuracy, faster response, and a network port.

◆ 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.

ACU20FD High-precision mass flow meter/flow controller The mass flow rate of a gas is measured using the principle of differential‑temperature calorimetry based on capillary heat transfer, which is unaffected by temperature and pressure. The flow signal acquired by the sensor is amplified and compared with a setpoint voltage; the resulting error signal drives a control valve, thereby implementing closed‑loop regulation to maintain the flow through the channel at the desired setpoint.
