I. Product Overview

No “specific heat capacity” error; high‑precision data with real‑time feedback. Compact design for a more intuitive large‑screen experience. Supports multi‑parameter measurement, facilitating data analysis. Employs a DSP‑based controller to further enhance accuracy and reliability. Offers nearly a hundred gas options with seamless switching—no need to return the device for calibration. Supports USB Type‑C and Bluetooth, enabling flexible and versatile connectivity.

The ACU30FC series flow meters operate on the differential pressure principle, calculating flow rate based on the pressure drop generated as fluid passes through a throttling element. The device features built-in PID control and, when paired with an electromagnetic proportional control valve, enables precise flow regulation. The ACU30FC can measure multiple parameters, including gas mass flow, volumetric flow, pressure, and temperature, and transmits these measurements via RS‑485/RS‑232 interfaces to a touch screen or other external devices and control systems for data monitoring and analysis.
