Abstract
A level detection apparatus includes a wave guide or discrete sensors mounted in an outer flexible housing. A weight is attached to a distal end of the outer housing. A biasing spring is coupled to the opposite end of the outer housing for exerting a force on the outer housing to accommodate thermal expansion and contraction of the outer housing to maintain the weight in close proximity to the bottom surface of an enclosure in which the apparatus is mounted.
