ACU20FE

Coriolis mass flow meters are highly regarded for their measurement accuracy and insensitivity to fluid properties. The ACU20FE applies this technology to very low flow rate measurements and integrates a PID controller and batching functionality internally to achieve flow control or metering.

Coriolis mass flow meters 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. When fluid flows through the sensor loop, the Coriolis force causes a variable phase shift, which the sensor detects and transmits to a DSP processor on the integrated circuit board for calculation. The output signal generated from this variable phase shift is strictly proportional to the actual mass flow rate, achieving unparalleled high performance even under varying conditions such as pressure, temperature, density, conductivity, and viscosity.

The ACU20FE simultaneously measures and outputs mass flow, fluid density, and temperature, providing two levels of accuracy: ±0.25% for liquid measurement and ±0.5% for gas measurement. This is sufficient to meet the needs of most customers, applicable to various laboratory experiments and complex industrial environments.
