Abstract
A float-type liquid level gauge is provided for measuring the level within a tank of liquids such as liquified petroleum gases. The liquid level gauge includes a movable float arm (30) coupled by gears (46, 48) to a magnet shaft (26) and magnet (28) mounted in a rigid support arm (24) through a side-accessible shaft passage (110). The support arm is connected to the lower side of a gauge head (22) and the magnet extends into a passage (52) in the gauge head so as to be magnetically coupled to a level indicating dial (34) provided on the upper side of the gauge head.
