◆Capable of rapidly and accurately measuring the volumetric or mass flow rate of process fluids.
◆ Employs a custom-designed high-speed proportional control valve to achieve precise regulation of liquid volumetric flow rate and mass flow rate.
◆ Features a uniquely designed vent that easily releases air.
◆ Integrated multifunctional digital display, enabling users to set setpoints and adjust PID valve control 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 customer support, including technical consulting, prompt equipment calibration services, and a conditional lifetime warranty.
The ACU10L series of digital liquid flow controllers and flow meters 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 ACU10L liquid flow controller/flowmeter 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 of process fluids.
