Abstract
A liquid level sensor for use when filling containers with hydrocarbons or other liquids is disclosed. A fiber optic bundle is arranged to form a flow path for a light beam in such a manner that the flow path is interrupted when the liquid level reaches a predetermined part of the flow path. The fiber optic bundle can be arranged to sense the liquid level when it approaches and reaches a predetermined height and can be connected to a loading control system in order to automatically control the filling of a tank.
