ACU10FC

The ACU10FC differential pressure mass flow controller uses a differential pressure mass measurement principle with no thermal drift and no response lag. It can simultaneously display and output: instantaneous flow rate, cumulative flow rate, pressure, temperature, etc. When a control function is required, an electromagnetic proportional control valve and built-in PID control function can be added. Unlike thermal flow meters, the ACU10FC has no additional "specific heat capacity" error when using gas conversion coefficients. Therefore, even if the measured gas is different from the calibration gas at the factory, it will not affect the measurement accuracy.

II. Product Applications

The ACU10FC series differential pressure mass flow controllers are widely used in various industries, such as: process manufacturing, food analysis, analytical testing and measurement, etc. Multi-variable measurement and 50:1 adjustable range ratio allow a single ACU10FC differential pressure mass flow controller to replace the functions of multiple devices. Accuracy of 1%, repeatability of 1%, and a control response time of less than 200 milliseconds ensure normal operation of the process gas.
