Abstract: 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.

Abstract: Devices, methods, and related systems are described for measuring a property of a fluid, including density, in a subterranean environment. A device includes a pressure housing having one or more windows formed in the pressure housing and a flow device arranged in the pressure housing for the fluid to flow through the flow device. Further, a radiation source is mounted within the pressure housing approximate a first source window configured to generate particles into the fluid. The device includes a detector supported by the pressure housing and positioned approximate a first detector window of the one or more windows. The first detector window is located between the detector and the flow device. The detector can be a solid state beta particle detector with a wide band gap, such as the diamond detector, and the radiation source can be a beta particle source, such as a strontium 90 source.
