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 valve assembly having a body, a float assembly, a switch magnet, and a sealing surface that opens or closes a block and bleed valve in response to movement of the float assembly. The float assembly may be pivotally attached to the body at a pivot axis. The float assembly may have a first end and a second end opposite the first end, where the pivot axis is located between the first end and the second end. The float assembly may further comprise a float attached to the first end and a float magnet attached to the second end, such that raising the float causes the float magnet to lower and lowering the float causes the float magnet to rise. The switch magnet may be responsive to movement of the float magnet, and the sealing surface may be responsive to movement of the switch magnet.

Abstract: A float operated liquid level switch having a body, a float assembly, a switch magnet, and a needle plug. The float assembly may be pivotally attached to the body at a pivot axis. The float assembly may have a first end and a second end opposite the first end, where the pivot axis is located between the first end and the second end. The float assembly may further comprise a float attached to the first end and a float magnet attached to the second end, such that raising the float causes the float magnet to lower and lowering the float causes the float magnet to rise. The switch magnet may be responsive to movement of the float magnet, and the needle plug may be responsive to movement of the switch magnet.

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.
