ACU20L Series

The ACU20L is a high-precision series of liquid flow controllers/flow meters. This product series employs a differential-pressure mass measurement principle that features no thermal drift and no response hysteresis. It can simultaneously display and output parameters such as instantaneous flow rate, cumulative flow rate, pressure, and temperature. When control functionality is required, an electromagnetic proportional control valve and built-in PID regulation capabilities can also be added.

I. Product Overview

◆ Differential pressure principle, offering higher accuracy and faster response.

◆ Can quickly and accurately measure the volumetric flow rate/mass flow rate of process liquids.

◆ Features uniquely designed vents that allow air to escape effortlessly.

◆ Instantaneous and cumulative flow rates, as well as temperature, can be displayed simultaneously.

◆ Integrated PID controller regulates flow.
