ACCU ACU20FE Coriolis Mass Flow Controller / Meter

The ACCU ACU20FE series is a Coriolis mass flow controller and flow meter for high-precision measurement of liquids and gases. Because the Coriolis principle measures mass flow directly, the reading does not depend on the physical properties of the fluid, which makes the series well suited to very small flow rates in the laboratory as well as to demanding industrial processes. Besides mass flow, the instrument also measures fluid density and temperature at the same time.

Unlike most comparable instruments, the ACU20FE integrates a PID controller and a batch function, so it can perform closed-loop flow control and dosing of a set quantity without external electronics.

Key features

• Accuracy ±0.25% F.S. for liquids and ±0.5% F.S. for gases; repeatability ±0.05% F.S.
• Direct mass flow measurement, no thermal or time drift
• Fast response: <0.2 s (controller), <0.1 s (meter)
• Recovers a stable reading within 400 ms after shocks or vibration
• Handles high-viscosity liquids and high-density fluids such as lubricating oil and liquid nitrogen
• Simultaneous output of mass flow, density and temperature
• Integrated PID control and batch (dosing) function

Applications

Semiconductor manufacturing, food processing, chemical and formulation research, petrochemicals and energy, atmospheric and emissions monitoring, fuel cell testing (H₂/O₂ flow control), pharmaceutical production.
