Vibrating-Wire Viscometers for Liquids at High Pressures

  title={Vibrating-Wire Viscometers for Liquids at High Pressures},
  author={Marc J. Assael and Claudia Pinto Marques Souza de Oliveira and William A. Wakeham},
The design and operation of two independent vibrating-wire viscometers are described. The instruments are intended for operation in the liquid phase at pressures up to 300 MPa and have been designed specifically for this purpose using the detailed theory of the device. Extensive evidence is adduced to demonstrate that the operation of the viscometers is consistent with the theory. Although the instruments attain a precision in viscosity measurements of • when used in an absolute mode the… CONTINUE READING
