Abstract
An apparatus for measuring a fluid level in a tank comprises a housing including a level indicator for displaying a measured fluid level in the tank. A rod extends from the housing and a float is adapted to travel along the rod. A first end of an elongated flexible member is attached to the float and an opposite end of the elongated flexible member is attached to a spool. The spool stores at least a portion of the elongated flexible member. The apparatus further includes a spring adapted to urge the spool to automatically uptake portions of the elongated flexible member as the float travels towards the housing and to allow the elongated flexible member to unwind from the spool as the float travels away from the housing.
