Abstract
Embodiments described herein relate to a flow meter assembly. The inline flow meter assembly includes a housing, an elongated flow member, and a piston. The housing includes a fluid passage. The elongated flow member has a shaft portion and an opposite fluid flow portion. The fluid flow portion has an outer peripheral surface. The shaft portion is coupled to the housing. The piston has a plate. The plate has a plate orifice. The piston and the plate move axially between a no flow position where the outer peripheral surface of the fluid flow portion is engaged with the plate orifice to prevent a fluid flow and a full flow position where the outer peripheral surface of the fluid flow portion is disengaged with the plate orifice such that the fluid flow enters the plate orifice and passes through the fluid passage in the axial direction of movement of the piston.
