Flow Coriolis Flow Meter



Promass Q 300

Promass Q 300 provides the highest measurement accuracy for mass flow, volume flow and density. Being the preferred choice for custody transfer applications, it has also been optimized for liquid applications where entrained gas is known to be present. The compact transmitter offers high flexibility in terms of operation and system integration: access from one side, remote display and improved connectivity options. Heartbeat Technology ensures compliance and process safety at all times.


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.
