Abstract: A modular and reversible manifold assembly for a pump calibration gauge. The assembly includes a tubular body having a first end and an opposed second end. A first inlet connection extends substantially perpendicular to the tubular body. A gauge connection on the first end of the tubular body is provided for connection to a pump calibration gauge. A pump connection on the second end of the tubular body is provided for connection to a metering pump. A second inlet connection extends substantially perpendicular to the tubular body opposed to the first inlet connection wherein either the first or second inlet connection is connected to a liquid storage tank or another modular and reversible manifold assembly.

Abstract: A chemical injector for injecting fluid chemical into a pipeline having an axis wherein the pipeline has fluid flow moving from an upstream to a downstream direction. The chemical injector includes an injector tube having an axis substantially perpendicular to the axis of the pipeline. An injector tube tip extends from the injector tube having an angled end, wherein the angled end forms a line extending from the injector tube axis toward the downstream direction at an acute angle. A circular aperture through the tube tip angled end of the injector tube assists in dispersing the fluid chemical in the pipeline.

Abstract: An armored sight gauge assembly of the type having a sight tube that is placed between first and second spaced apart fittings to show a liquid level comprising an elongated main body positioned between and permanently connected to the first and second fittings. The main body incorporates a flanged U-shaped frame member to which there is removably affixed a transparent sight tube shield. A sight tube assembly substantially surrounded by the flanged U-shaped frame member on three sides and is insertably captured by the first and second fittings. A valve assembly and ball check shutoff is incorporated within the internal portion of each of the first and second fittings as is a misalignment union which is removably attached to each fitting.
