I. Product Overview
No “specific heat capacity” error, with high-precision data delivered in real time. Compact design for a more intuitive experience on the large display. Supports multi-parameter measurement for easy data analysis. Employs a DSP-based main controller to further enhance accuracy and reliability. Allows seamless switching among nearly 100 gases—no need to return the device to the factory for calibration. Supports USB Type-C and Bluetooth, enabling flexible and versatile device connectivity.
The ACU30FC series flow meters operate on the differential-pressure principle, calculating flow rate based on the pressure difference generated as the fluid passes through a throttling element. The instrument features built-in PID control functionality 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 communication protocols such as RS485 and RS232 to a touch screen or other external devices and control systems for data monitoring and analysis.
