Flow Coriolis Flow Meter

EH Promass

Technology

Coriolis flow meters are designed to measure mass flow, volume flow, density, and temperature. Coriolis forces are generated in oscillating systems when a liquid or a gas moves away from or towards an axis of oscillation. A Coriolis measuring system is of symmetrical design and consists of one or two measuring tubes, either straight or curved. Sensors at the inlet and outlet ends register the resultant phase shift in the tube's oscillation geometry. The processor analyzes this information and uses it to compute the rate of mass flow. The oscillation frequency of the measuring tubes themselves, moreover, is a direct measure of the fluids' density.
