ABSTRACT:
A liquid float gage assembly for a fluid reservoir includes magnet containing float in a vertical tube having an adjacent vertically spaced reed switch arrangement. The float is capsule shaped with an extended round cylindrical portion having rounded axial ends; and the magnet tends to be attracted to the closest reed switch to bias the float against the inner surface of the tube. The tube has a horizontally cross-sectional shape substantially matching and just larger than an axial section of the float so that the float has a stable floating orientation with a horizontal axis and is capable of rolling during vertical movement within the tube to reduce friction due to liquid surface tension between the float and the tube. The magnet has poles at axially opposing ends thereof within the float and a circumferentially consistent spacing relative to the outer surface of the float so as to provide a substantially non-varying magnetic field strength radially adjacent the float as the float rolls.
