CORIOLIS FLOW METER AND METHOD FOR DETERMINING FLOW CHARACTERISTICS

CORIOLIS FLOW METER AND METHOD FOR DETERMINING FLOW CHARACTERISTICS

A Coriolis flow meter (5) is provided according to an embodiment of the invention. The meter (5) includes one or more flow conduits (103), at least two pickoff sensors (105, 105′) affixed to the one or more flow conduits (103), a driver (104) configured to vibrate the one or more flow conduits (103)...

description A Coriolis flow meter (5) is provided according to an embodiment of the invention. The meter (5) includes one or more flow conduits (103), at least two pickoff sensors (105, 105′) affixed to the one or more flow conduits (103), a driver (104) configured to vibrate the one or more flow conduits (103), and meter electronics (20) coupled to the at least two pickoff sensors (105, 105′) and to the driver (104). The meter electronics (20) vibrate the one or more flow conduits (103) of the flow meter (5) with a first vibration frequency and in a first out-of-phase bending mode, measure a first vibrational response, with the first vibrational response being generated in response to the first vibration frequency, vibrate the one or more flow conduits (103) with at least a second vibration frequency and in the first out-of-phase bending mode, measure a second vibrational response, and determine at least a mass flow rate and a viscosity using the first and second vibrational responses.
