Abstract of the Disclosure The instrument disclosed herein is designed for measuring flow rates and densities of moving fluid streams, including liquids, gases, slurries, and fluids which contain solid materials. In one embodiment of this instrument, a conduit section, which has a 90 degree bend therein, is placed in a transfer line which carries the fluid stream to its use point. Defined within the conduit section is a chamber, which is located at the bend in the conduit. Installed within the chamber is a force measuring transducer and a piston, which is is contact with the diaphragm assembly of the transducer. In operation, a part of the moving fluid is diverted into the chamber, to equalize fluid pressure across the diaphragm assembly of the transducer and the piston. This removes the effect of fluid pressure on the flow rate and density measurement, and allows the moving fluid to displace the piston by the force exerted by the fluid. The transducer registers the force and transmits it to a computer, which converts it to a flow rate as a function of the force. A separate transducer measures the velocity of the stream and this measurement is converted to a density value.
