ACU20FE Series

Coriolis mass flowmeters are highly regarded for their measurement accuracy and insensitivity to fluid properties. The ACU20FE applies this technology to very low‑flow measurements and features an integrated PID controller and batching functionality, enabling flow control or precise batch dosing.

Coriolis mass flowmeters are highly regarded for their measurement accuracy and insensitivity to fluid properties. The ACU20FE incorporates a uniquely shaped single-loop sensor that forms part of an oscillating system. As the fluid flows through the sensor loop, Coriolis forces induce a variable phase shift, which the sensor detects and transmits to a DSP processor on the integrated circuit board for computation. The resulting output signal is strictly proportional to the actual mass flow rate, delivering unparalleled high performance even under varying operating conditions such as changes in pressure, temperature, density, conductivity, and viscosity.

The ACU20FE simultaneously measures mass flow rate, fluid density, and temperature, with output in all three parameters, offering two accuracy levels: ±0.25% for liquids or ±0.5% for gases. This performance is sufficient to meet the needs of most customers, making it suitable for a wide range of applications—from laboratory experiments to demanding industrial environments.
