Abstract

See full text

Devices, methods and systems for determining one or more properties of at least one fluid sample. A tube configured to receive the at least one fluid sample wherein the tube is placed in a pressure housing. Further, an excitation source configured to generate vibration of the tube whereby a circulation of an electrical current along a portion of the tube is subjected to at least one magnetic field produced by at least one magnet. Further still, at least one vibration sensor that converts vibrations of the tube into a measurement signal. Finally, a processor that receives the measurement signal determines a resonant frequency from the measurement signal using a frequency measuring device to determine a property of the one or more properties of the at least one sample fluid.
