I. Product Overview
◆ Quickly and accurately measures the volumetric or mass flow rate of process gases, liquids, or vapors
◆ Utilizes custom-designed high-speed proportional control valves for precise regulation of media volumetric or mass flow rates
◆ When measuring liquids, the uniquely designed vent hole allows air to be easily released.
◆ Setpoints and PID valve adjustments via the touch-enabled display, with open analog input/output and RS-485 digital communication capabilities.
◆ No movable components or heating elements inside; passes vibration tests and is insensitive to installation orientation.
◆ Utilizing internally compensated laminar flow differential pressure technology ensures that the fluid maintains laminar flow even at high flow rates.
◆Offering comprehensive user support, including technical consultations, fast equipment calibration services, and a conditional lifetime warranty.
II. Product Applications
The ACU20FCH series high-temperature mass flow meters/controllers are widely used across various industries, including process manufacturing, food analysis, and analytical testing and measurement applications.
Multi-variable measurement and a 50:1 adjustable range allow a single ACU20FCH high-temperature mass flow meter/controller to replace the functionality of multiple devices. With an accuracy of 0.5%, repeatability of 0.5%, and a control response time of less than 200 milliseconds, this ensures reliable operation for process gases, liquids, and vapors.
