Abstract
A fluid level sensor has a sensing element mounted to the end of a member that requires a predetermined orientation for accurate fluid level detection. A knob on the housing of the sensor operatively connected to the member includes an orientation indicator. The member includes a thread that extends a distance along the member that corresponds to a thickness of the wall into which the member of the fluid level sensor is inserted. A portion of the thread extends beyond the wall to enable bidirectional rotation of the knob to position the element for accurate fluid level detection while a portion of the thread remains within an opening in the wall to enable pressure to be applied to an O-ring seal mounted about the member to prevent leakage from the bore.
