<p>A float-type liquid level gauge is provided for measuring the level of a liquid such as LPG within a horizontally oriented cylindrical tank (228). The gauge includes a movable pivot arm (212) supporting a float arm assembly (225) and coupled by gears (207, 214) to a magnet shaft (206, 208) and magnet (210) mounted in a rigid support arm (204) through a sideways-securing shaft channel (209). The support arm is connected to the lower side of a gauge head (202) and the magnet extends into a passage (52) in the gauge head so as to be magnetically coupled to a level indicating dial (226) provided on the upper side of the gauge head. The lower portion (302) of the support arm is angled and offset with respect to a longitudinal axis (265) such that a high ratio can be obtained between the gears while still permitting the components of the gauge to pass through the opening of a standard pressure fitting (234).</p> |
