摘要: A measurement device (104) is provided that determines fluid properties from vibration frequencies of a sample cavity (first 108) and a reference cavity (second 108). In one embodiment, the measurement device includes a sample flow tube (first 108), a reference flow tube (second 108), vibration sources (110) and detectors (12) mounted on the tubes, and a measurement module. The sample flow tube receives a flow of sample fluid for characterization. The reference flow tube is filled with a reference fluid having well-characterized properties. The measurement module employs the vibration sources to generate vibrations in both tubes. The measurement module combines the signals from the vibration detectors on the tubes to determine properties of the sample fluid, such as density, viscosity, compressibility, water fraction, and bubble size.
