摘要: A vibrating wire viscometer has been developed with an electrically insulating tensioning mechanism. It used two wires, one of diameter 0.05 mm the other 0.15 mm, to measure viscosity methylbenzene and reference fluids viscosities (14 240) mPa·s at T = 298 K p 0.1 MPa temperatures in range from (298 373) pressures below 40 MPa, where covers (0.3 100) uncertainty < 0.6 %. The results so obtained differ literature values by < 1 Measurements 0.150 301 demonstrate that upper operating is 200 about 3
