Viskositätskorrigiertes Durchflußmeßgerät

A digital flowmeter can include a vibratable conduit with a mixture of a liquid and a gas flowing therethrough. A driver can be connected to the conduit and can be operable to impart motion to the conduit where a sensor can also be connected and can be operable to sense the motion of the conduit. A...

Zusammenfassung:	A digital flowmeter can include a vibratable conduit with a mixture of a liquid and a gas flowing therethrough. A driver can be connected to the conduit and can be operable to impart motion to the conduit where a sensor can also be connected and can be operable to sense the motion of the conduit. A digital transmitter can also be connected to the conduit and can include a void fraction determination system configured to determine a gas void fraction of the mixture, a viscosity determination system configured to determine a viscosity of the liquid in the mixture, and a flow parameter correction system operable to determine a flow parameter associated with the flowing mixture, based on the gas void fraction and the viscosity.
