Abstract:
1. A flowmeter for measuring fluid parameters in a hydraulics system, comprising: (a) a tube having an inlet and an outlet, and having a generally cylindrical inner geometry for building pressure proportional to flow, as a function of fluid viscosity; (b) a temperature transducer capable of generating a signal proportional to the temperature of said tube and a fluid within said tube; (c) one or more transducer disposed at the inlet and the outlet of said tube for generating a signal proportional to pressure of the fluid within said tube; (d) a device for digitizing the signals generated by said transducers; and (e) a microprocessor configured to computationally normalize the geometry of said tube and viscosity of the fluid in said tube by means of transducers wherein the following relationship holds V/T=C
