Meter tube assembly

A metering tube assembly for regulating flow of a fluid, the metering tube assembly comprising:

• a fluid inlet;
• a fluid outlet;
• a plurality of stacked metering plates located between the fluid inlet and the fluid outlet, each of the plurality of stacked metering plates defining a fluid passageway in fluid communication with the fluid inlet and fluid outlet, and having a length greater than a thickness of the metering plate, wherein the stacked metering plates are arranged such that a fluid flowing through the metering plates flows sequentially through the fluid passageways of the metering plates;
• an inlet plate including a main body and an integral inlet port extending in a first axial direction from the main body, the inlet port defining the fluid inlet;
• and
• an outlet plate including a main body and an integral outlet port extending in a second axial direction, opposite the first axial direction, from the main body, the outlet port defining the fluid outlet;
• a plurality of gaskets disposed between the plurality of stacked metering plates, each of the plurality of gaskets having a central aperture placing ends of the fluid passageways of adjacent metering plates in fluid communication with each other while separating lengths of the fluid passageways of adjacent metering plates;
• wherein the plurality of stacked metering plates, the plurality of gaskets, the inlet plate, and the outlet plate are stacked together to form an assembly with an outer perimeter defined by the plurality of stacked metering plates, the plurality of gaskets, the inlet plate, and the outlet plate, the outer perimeter having a dimension of about 1.5 inches;
• wherein the plurality of stacked metering plates, the inlet plate, and the outlet plate include a plurality of coaxially aligned apertures through which fasteners extend to rigidly secure the plurality of stacked metering plates, the inlet plate, and the outlet plate together.
