A gauge assembly (10) is disclosed which incorporates a voltage divider circuit to provide reliable and accurate measurement of a fluid level within a tank (16) or other environment. A pointer assembly (52) pivots about an axis (42) in response to a moving float to indicate the fluid level. A plurality of contact arms (92, 94, 96) extending from a contact plate (58) on the pointer assembly (52) resiliently engage a point (91) along a resistive element (84). The ends of the resistive element (84) form first and second contacts (86, 88) while the point (91) of contact between the contact arms and resistive element is connected to a third contact (90) to form a voltage divider circuit.

A gauge assembly for measuring a fluid level, comprising: a gauge including; (a) a resistive element having first and second ends; (b) a first contact formed at the first end of the resistive element; (c) a second contact formed at the second end of the resistive element; (d) a movable element having a conductive arm in electrical contact with the resistive element at a point along the resistive element; and (e) a third contact electrically connected to the conductive arm; and means for sensing the level of the fluid and for moving the movable element and the conductive arm to a point on the resistive element corresponding to the fluid level sensed, the gauge thereby forming a voltage divider circuit indicating the fluid level.
