Claim 0:
1. A fluid sensor comprising:
a cylindrical venturi including a pair of coaxial cylinders and having a gap between an outer surface of a first coaxial cylinder and an inner surface of a second coaxial cylinder, the cylindrical venturi producing a controlled thickness of non-stratified fluid flow through the gap;
a first fluid sensor located on an inlet to the cylindrical venturi to measure at least an input fluid pressure;
a second fluid sensor located just before an outlet of the cylindrical venturi to measure at least an output fluid pressure;
a capacitive sensor integral to the cylindrical venturi, the capacitive sensor including a pair of coaxial cylindrical metal surfaces, one located on the outer surface of the first coaxial cylinder and the other located on the inner surface of the second coaxial cylinder, for detecting the dielectric properties of the fluid flowing through the venturi.
