Abstract
A viscometer () is provided, for determining a viscosity of a gas therein. The viscometer () comprises a driver () and a planar vibratory member () vibratable by the driver (), that comprises a body () and a vibratable portion () emanating from the body (), wherein the vibratable portion () comprises a plurality of vibratable cantilevered projections. At least one pickoff sensor () is configured to detect vibrations of the vibratory member (). Meter electronics () comprise an interface () configured to send an excitation signal to the driver () and to receive a vibrational response from the at least one pickoff sensor (), measure a Q and resonant frequency of the planar vibratory member (), and to determine a viscosity () of the gas therein using the measured Q and the measured resonant frequency.
