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.
