I. Product Overview

◆ Enables quick and accurate measurement of volumetric/mass flow rates for process liquids

◆ Employs a custom-designed high-speed proportional control valve for precise regulation of liquid volumetric or mass flow rates.

◆ Features a uniquely designed vent that effortlessly releases air

◆ Integrated multi-function digital display screen allows users to control setpoints and PID valve adjustments effortlessly—simply by operating the on-screen buttons—while also providing flexible analog input/output options 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 ACU10L series of digital liquid flow controllers/flow meters are widely used across various industries, including process manufacturing, food analysis, analytical testing, and metrology.

Multi-variable measurement and a 50:1 adjustable range allow 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 smooth operation of process fluids.
