Abstract
Vibrating wire viscometers are disclosed herein. An example viscometer includes a housing defining a chamber and a wire holder disposed in the chamber. The wire holder has an elongated, electrically insulating body and a channel extending along a length of the body. A wire is at least partially disposed in the channel and coupled to the wire holder at opposing ends of the wire holder to tension the wire and electrically isolate the wire from the housing.
