15 Definition Coriolis Force u An apparent deflection of the path from an object that moves within a rotating system u Definition by Gustave-Gaspard Coriolis (1835) INSA 15 / 14

16 Coriolis Force Example u In the inertial frame of reference the black object moves in a straight line. u However, the observer (red dot), who is standing in the rotating (non-inertial) frame of reference, sees the object as following a curved path due to the Coriolis and centrifugal forces present in this frame. INSA 16 / 14

17 Coriolis Effect Demonstration u No flow: hose is in balance u Flow: out of balance (distortion of the hose) causing a phase shift between in- and outlet. INSA 17 / 14

28 mini CORI-FLOW Pump-control u mini CORI-FLOW directly operating (speed controlled) pump u Using internal fast unfiltered sensor signals results in very fast control loops to enable highly stable and fast response flows u stable up to <0.1% of desired flow Features: - No pressurized vessel needed with problems of gas dissolved in liquid - Continuous flow control in Mass and Volume - No external PID-controller required - Exact filling and dosing using speed controlled pump - Flow is independent of process back pressure - Stable pump control also in low flow range - High rangeability (up to 1:2000, depending on sensor and speed control) INSA 28 / 14
