Fluid gauging apparatus using magnetostriction and a stick gauge

摘要

Apparatus for detecting fluid level in a container (10), comprises a housing adapted to be disposed in the container; a float (20) with an associated magnetic element, the float position corresponding to fluid level in the container (10); a magnetostrictive sensor (12) disposed inside the housing; and a stick gauge disposed inside the housing; the magnetostrictive sensor and the stick gauge each being operable to determine the float position. <IMAGE> <IMAGE>
