Abstract

An inline fluid properties measurement device that includes a tube defining an interior space that includes at least one non-cylindrical volume, and having a fluid entrance and exit, and capable of conducting fluid from the fluid entrance to the fluid exit, through the at least one non-cylindrical volume. An excitation and sensing transducer assembly is positioned to torsionally drive the tube and to sense torsional movement of the tube and a controller is programmed to drive the excitation and sensing transducer to drive the tube in torsion, thereby translating the fluid in the at least one non-cylindrical volume, and to sense torsional movement of the tube, thereby producing a sense signal. Finally, a signal analysis assembly responsive to the sense signal to form a measurement of at least one property of the fluid.
