I. Product Overview
◆ Differential pressure principle, fast response speed, and accuracy up to ±0.5% F.S.
◆ Suitable for various low-pressure and high-pressure pipelines
◆ Short warm-up time, zero drift, and high reliability
The ACU20FC differential-pressure mass flow controller employs a differential-pressure mass measurement principle that features zero thermal drift and no response lag. It can simultaneously display and output parameters such as instantaneous flow rate, cumulative flow rate, pressure, and temperature. When control functionality is required, an electromagnetic proportional regulating valve and built-in PID control function can also be added. Unlike thermal mass flow meters, the ACU20FC differential-pressure mass flow controller does not introduce additional “specific heat capacity” errors when using gas conversion factors. Therefore, even if the gas being measured differs from the calibration gas used at the factory, the measurement accuracy remains unaffected.
