ABSTRACT:
A bypass valve assembly is disclosed for use with a fluid flow meter of the type having a housing, an inlet, an outlet, a fluid passage which fluidly connects the inlet to the outlet and a flow rate responsive member within the fluid passage. The bypass valve assembly comprises a tubular body open at one end in which is secured to the flow meter housing so that the open end of the tube registers with the flow meter inlet. A valve member is contained within the tube and is urged to a closed position by a helical spring. In its closed position, the valve member directs all of the influent to the flow meter through the passage. When the fluid flow rate into the flow meter exceeds a predetermined amount, the valve member moves to an open position against the force of the helical spring thus bypassing the influent directly to the flow meter outlet.
