LIQUID LEVEL GAUGE WITH FLOAT GUIDES

摘要

A liquid level gauge includes a mounting head and a sensor assembly with a support tube that extends into a tank from the mounting head. A gauge rod is positioned in a support tube for selective movement out of the tank for visually determining the liquid level. A magnet is associated with the gauge rod and couples with a magnet associated with a float that slides along the support tube so that the gauge rod and float are selectively coupled together. A pair of spaced bearings are mechanically retained within the float structure with retaining rings and spaced projections located on opposite sides of each bearing. In this manner, the float slides more freely along the support tube, allowing more accurate readings while minimizing failure.

1. A liquid level gauge for determining the level of liquid within a container, the liquid level gauge comprising:
a mounting head adapted for connection to the container; and a sensor assembly adapted to extend into the container from the mounting head, the sensor assembly comprising:
a support tube extending downwardly from the mounting head;a gauge rod positioned in the support tube for selective movement out of the tank for visually determining the liquid level;a first magnet connected to the gauge rod;a float assembly comprising:
a float surrounding the support tube for sliding therealong in response to a change in liquid level;a second magnet for selective coupling to the first magnet so that the gauge rod and float are selectively coupled together;at least a first bearing positioned in the float and surrounding the support tube for sliding movement of the float therealong in response to change in liquid level; andat least a first support ring positioned at least adjacent to the first bearing to prevent the first bearing from becoming dislodged from the float.
