Abstract
A liquid level detection apparatus has an outer semi-rigid, flexible tube closely surrounding an inner, non-permeable tube containing a magnetostrictive wire. The outer tube prevents collapse of the inner tube during bending and flexing of the inner tube to enable the inner tube to be bent or coiled during storage, shipping, and installation.
