Installation and method for determining the level and density of a liquid in a tank, using a single immersed bubble probe

An installation and method for determining the level and density of a liquid in a tank. A reference probe leads into the tank, above the liquid. A single bubble probe is connected by a valve to the reference probe. The bubble probe extends into the tank and has a widened section disposed in the liqu...

Beschreibung
Zusammenfassung:	An installation and method for determining the level and density of a liquid in a tank. A reference probe leads into the tank, above the liquid. A single bubble probe is connected by a valve to the reference probe. The bubble probe extends into the tank and has a widened section disposed in the liquid. Compressed air is injected into the reference probe and the bubble probe. In an initial state, the valve is opened and there is no pressure difference between the reference probe and the bubble probe. The valve is then closed and the pressure difference between the reference probe and the bubble probe is measured. The level and density of the liquid is determined from measured values of the pressure difference.
