Systems and methods for an inline flow meter assembly

A flow meter system comprising:

• a flow control assembly comprising:
• a housing having a fluid inlet and a fluid outlet defining a fluid passage;
• an elongated flow member having a shaft portion and an opposite fluid flow portion having an outer peripheral surface, the shaft portion is coupled to the housing to prevent movement of the shaft portion;
• and
• a piston having a plurality of bores and having a plate, the plate has a plate orifice, the piston and the plate move in an axial direction between a no flow position where the fluid flow portion is engaged with the plate orifice to prevent a fluid flow and a full flow position where the fluid flow enters the plate orifice, through the plurality of bores, and passes through the fluid passage in the axial direction of movement of the piston, the fluid inlet, the fluid outlet and the fluid passage are aligned on the axial direction of movement of the piston,
• a flow meter assembly comprising:
• a display device;
• a dial assembly;
• an arm coupled to the dial assembly and configured to move across a surface of the piston and through an angle based on a fluid flow rate, and
• a pointer assembly coupled to the dial assembly;
• wherein the arm translates the axial direction of movement of the piston into a rotational movement to the dial assembly such that the pointer assembly displays the fluid flow rate on the display device.

A method of changing a current flow rate to a desired flow rate of an inline flow control assembly, the method comprising:

• removing a flow fastener from a receiving cavity of an elongated flow member;
• removing the elongated flow member from a first portion of a housing, the housing having a fluid inlet and a fluid outlet defining a fluid passage;
• removing a pair of plate fasteners from a plate such that the plate with an orifice is separated from a piston and removed from the housing;
• choosing a replacement elongated flow member and corresponding plate that correlate to the desired flow rate;
• inserting the corresponding plate and installing the pair of plate fasteners such that the corresponding plate with the orifice is coupled to the piston to move in axial direction;
• and
• positioning the replacement elongated flow member and installing the flow fastener into the receiving cavity such that the elongated flow member is coupled to the first portion of the housing,
• wherein the piston, the plate, the fluid inlet, the fluid outlet and the fluid passage are aligned on the axial direction of movement of the piston.
