Abstract
A level sensor, method of treating cooperating surfaces of a level sensor, and method of installing a level sensor, wherein the level sensor may include an elongated tube having an outer surface, and a float carrier having an inner surface, and wherein the outer surface and the inner surface form cooperating surfaces, and wherein at least one of the surfaces comprises a Self-Assembled Monolayer of Phosphonate (SAMP). The method of treating cooperating surfaces includes applying a coat of a Self-Assembled Monolayer of Phosphonate (SAMP) composition to at least one of said cleaned and dried surfaces of said tube and float carrier to form treated components. The method of installing may include installing said level sensor into a section of a crude oil service operation.
