Abstract
The present invention relates to a flowmeter for measuring flow rate of a fluid independently of fluid viscosity or density. In at least on embodiment, the flowmeter includes an inlet, an outlet, and a cylindrical chamber. The flowmeter also includes an impeller assembly positioned within a cylindrical chamber for rotation at a variable speed. In at least one embodiment, the flow rate of the fluid is determined when a pressure differential between the fluid in the let and fluid in the outlet becomes substantially zero.
