Abstract
The Coriolis force flowmeter of the present invention comprises a first sinuous conduit with a S-shaped midsection disposed on a first plane and a second sinuous conduit with a S-shaped midsection disposed on a second plane generally parallel to the first plane wherein the two sinuous conduits are disposed in an axisymmetric arrangement about an axis intermediate and parallel to the two planes. An electromagnetic vibrator exerting oscillatory forces to the midsections of the two sinuous conduits generates relative flexural vibrations therebetween. Two motion detectors respectively measuring the flexural vibrations of the two halves of at least one of the two sinuous conduits provides the difference in the flexural vibrations therebetween as a measure of mass flow rate of fluid moving through the two conduits.
