Abstract
A float-type liquid level gauge assembly is provided for measuring the level of a liquid in a tank. The liquid level gauge includes a gear housing for efficiently coupling the gears and accurately assembling and aligning certain components; a movable pivot arm assembly supporting a float arm assembly; and a gear on the pivot arm assembly coupled with a pinion gear located in the gear housing. The pinion gear has a shaped passageway which accepts a similarly shaped drive shaft. A single piece magnetic cap, which defines a bore correspondingly shaped to accept the shaped drive shaft such that it will not rotate relative to the drive shaft, is installed on the drive shaft. The drive shaft and the magnetic cap each include a positioning feature, such that when the positioning feature of the drive shaft engages the positioning feature of the magnetic cap, the magnetic cap is properly aligned with a magnet in a dial assembly. A float arm with an attached float assembly can be adapted to act as both the float arm and the counterweight for counter-balancing the float assembly.
