ACU30FC

The ACU30FC is a high-precision differential pressure flow controller/flow meter with a compact design and a large screen for ease of use. This series uses a differential pressure measurement principle without thermal drift or response lag, and can simultaneously display and output instantaneous flow, cumulative flow, pressure, and temperature.

I. Product Overview

No "specific heat capacity" error, high-precision data real-time feedback Compact design, larger screen for more intuitive experience Supports multi-parameter measurement for easy data analysis Uses DSP main control to further improve accuracy and reliability Nearly 100 kinds of gases can be freely switched without factory recalibration Supports USB Type-C and Bluetooth for flexible and diverse device connections.

The ACU30FC series flow meter adopts a differential pressure principle, calculating flow rate based on the pressure difference generated when fluid passes through a throttling element. The product has a built-in PID adjustment function, and when used with an electromagnetic proportional control valve, it achieves precise flow control. The ACU30FC can measure multiple parameters such as gas mass flow rate, volume flow rate, pressure, and temperature, and display a series of parameters through RS485/232 communication methods via a touch screen or other external devices and control systems for data monitoring and analysis.
