mini CORI-FLOW Ex d Series, Coriolis Mass Flow Meters and Controllers

The mini CORI-FLOW Ex d Coriolis mass flow meter offers integrated PID control for direct control of valves or pumps, thus constituting compact Coriolis mass flow control loops. This flow meter can also come with valves or pumps for use in Zone 1, but they must install outside the mini CORI-FLOW Ex d box and connect via the screw terminal.

Coriolis Flow Measurement Principle

The mini CORI-FLOW Ex d Series Coriolis low flow meters and controllers contain a uniquely shaped, single loop sensor tube, forming part of an oscillating system. When a fluid flows through the tube, Coriolis forces cause a variable phase shift, which is detected by sensors and fed into the integrally mounted pc-board. The resulting output signal is strictly proportional to the real mass flow rate. Coriolis mass flow measurement is fast, accurate, and inherently bi-directional. The mini CORI-FLOW Ex d features density and temperature of the fluid as secondary outputs.
