Title: Pivotal float for liquid level detection apparatus

Abstract: A float for a liquid level detection apparatus including a tube extendable through liquid in a tank. The float is a buoyant body slidably mounted about the tube and having a diameter passable through an aperture in the tank. The float is preferably formed of two separate bodies joined by spacers positioned to allow the body to pivot from a first position substantially axially in line with the tube for insertion and removal of the float with respect to the tank to a second position substantially perpendicular to the tube in operative floating engagement with the liquid surface in the tank. The spacers, in one embodiment, are in the form of pins arranged in pairs along opposite side edges of the two bodies and spaced apart along the length of the two bodies such that the innermost pins of the two pairs of pins define an aperture for mounting the bodies transversely about the tube in the second, floating position. A pin is mounted along one side edge of at least one of the bodies and is engagable with a hook inserted through the aperture in the tank to pivot the float to the first position for sliding removal from the tank.
