Abstract: Apparatus for measuring the mass flow of a fluid within a defined fluid stream including a conduit having two substantially parallel, flexible and continuous flow tubes fixedly mounted at their ends to a centrally positioned housing forming a flow splitter and a flow converger for directing the flow from the inlet and for directing the flow into the outlet between the apparatus and the fluid stream. The ends of each flow tube positioned proximal to one another and to the center of gravity formed by the shape of the flow tube. Each flow tube substantially forming a "B" shape having a first loop, a connecting portion and a second loop. The first and second loops being symmetrical with respect to the connecting portion and extending laterally from the center of gravity at a greater distance than the displacement of the connecting portion to the center of gravity.

Abstract: A conduit having two substantially parallel, flexible and continuous flow tubes fixedly mounted at their ends to a centrally positioned housing The ends of each flow tube positioned proximal to one another and to the center of gravity formed by the shape of the flow tube. Each flow tube substantially forming a "B" shape having a first loop, a connecting portion and a second loop. The first and second loops being symmetrical with respect to the connecting portion and extending laterally from the center of gravity at a greater distance than the displacement of the connecting portion to the center of gravity. The flow tubes being oscillated in opposing modes at the connecting portion so as to produce a measurable Coriolis reaction force by the fluid on the flow tubes.

Abstract: A hydrodynamic fluid divider is provided whereby by a shunt line directs a portion of the overall flow of a defined fluid stream through a flow measuring device, such as a Coriolis mass flow meter. The proportion of the shunt line flow portion is determined by the relationship of various fluid restrictions within the shunt line and the main line of the divider. The measured flow value for the shunt line flow is utilized along with a scale-up factor to determine the overall flow through the divider. The proportional relationship of the shunt line to the overall flow permits a reduction in the size and operational requirements for the flow measuring device.
