ACU10FCH Series

The ACU10FCH series high-temperature mass flow meters enable rapid and accurate measurement of volumetric and mass flow rates for gases, liquids, and steam. The ACU10FCH series high-temperature mass flow controllers utilize a custom-designed high-speed proportional control valve to achieve precise regulation of volumetric and mass flow rates for gases, liquids, and steam.

◆Capable of rapidly and accurately measuring the volumetric and mass flow rates of process gases, liquids, and vapors.

◆ A custom-designed high-speed proportional control valve is used to precisely regulate the medium’s volumetric flow rate and mass flow rate.

◆ When measuring liquids, the uniquely designed vent hole allows air to be easily expelled.

◆ Integrated multifunction digital display, enabling users to control setpoints and PID valve adjustments directly via on-screen buttons, while also providing analog I/O and RS‑485 digital communication.

◆ No internal moving parts or heating elements; passes vibration testing and is insensitive to installation orientation.

◆ Utilizing an internally compensated laminar flow differential pressure technology, the fluid maintains laminar flow even across a wide range of flow rates.

◆We provide comprehensive user support, including technical consulting, prompt equipment calibration services, and a conditional lifetime warranty.

The ACU10FCH series high-temperature mass flow meters/controllers are widely used across various industries, including process manufacturing, food analysis, and analytical testing and metrology.

Multivariable measurement and a 50:1 adjustable span ratio enable a single ACU10FCH high‑temperature mass flow meter/controller to replace the functionality of multiple devices. With 1% accuracy, 1% repeatability, and a control response time of less than 200 milliseconds, it ensures reliable operation for process gases, liquids, and vapors.
