Abstract
A fluid capacitance sensor includes a device, receiving a stream of fluid, which converts the fluid flow to annular fluid flow. A capacitance sensing network has an internal capacitance substantially greater than the capacitance of the fluid. The capacitance sensing network measures the capacitance of the annular flowing fluid and provides a signal corresponding to the sensed capacitance of the fluid.
