ABSTRACT:
A device which monitors the through passage of incompressible fluids such as water that relies upon a nutating disk-type transducer associated with a spherical hollow core. The disk includes a spindle which precesses in the presence of a sensor. A display panel is driven by a microcontroller which converts the precession of the spindle to useful output as a function of time whereby the precession correlates with volume flow through the nutating disk transducer.
