ABSTRACT:
A system for measuring the level of liquid stored in deep tanks or vessels that allows the use of a lightweight, relatively non-toxic, non-corrosive gauge fluid of normal column height is disclosed. The system discloses a diaphragm manometer that alters a greater pressure from the tank liquid into a lesser pressure from the gauge fluid permitting such gauge fluid to be lightweight and making it unnecessary to use high density fluids which are usually toxic, contaminating and have other undesirable handling characteristics. The device can be used for open tanks, or, with adaptations, for sealed tanks. For open tanks, the device provides two sealed chambers having two opposing diaphragms. For sealed tanks, pressure neutralizing elements are added with one device providing three sealed chambers and two diaphragms with neutralizing connectors, and another providing three sealed chambers and three diaphragms.
