VISCOMETERS WITH VIBRATING WIRE Russian patent published in 2014 - IPC G01N11/00 

FIELD: instrumentation.

SUBSTANCE: this invention relates, in general, to testing of viscosity of well fluids, and more specifically, to viscometers with a vibrating wire. A viscometer is proposed with a vibrating wire. Certain versions of jackets of a viscometer with a vibrating wire include a pipeline, stretching via a jacket and providing for impact at the first wire by well fluid, a cavity in the jacket for placement of a magnet and laying of one or several additional wires from a pipeline to a generator of signals, the first and second electroconducting supports, mechanically connected with the jacket for retention of the first wire in tight condition in a pipeline, and a seal, mechanically connected to the jacket for prevention of access of well fluid to the magnet.

EFFECT: increased accuracy of viscosity measurement.
