◆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.
◆ Setpoints and PID valve control via a touch‑screen display, with analog I/O and RS‑485 digital communication also available.
◆ 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 flow range.
◆We provide comprehensive customer support, including technical consulting, prompt equipment calibration services, and a conditional lifetime warranty.
The ACU20FCH series high-temperature mass flow meters/controllers are widely used across various industries, including process manufacturing, food analysis, analytical testing, and metrology.
Multivariable measurement and a 50:1 adjustable span ratio enable a single ACU20FCH high‑temperature mass flow meter/controller to replace the functionality of multiple instruments. With an accuracy of 0.5%, repeatability of 0.5%, and a control response time of less than 200 milliseconds, it ensures reliable operation for process gases, liquids, and vapors.
