ABSTRACT:
Apparatus for detecting the magnitude of a property of a fluid including a body mounted on a torsion spring that is oscillated by a feedback of alternately an in-phase and an out-of-phase signal from an amplifier having a gain adequate to sustain the oscillations. If the in-phase signal has a period directly proportional to T.sub.n, the out-of-phase signal has a frequency directly proportional to f.sub.h, and the out-of-phase period is directly proportional to T.sub.h, then the magnitude of the property p is determined by the digital computation of
