ABSTRACT:
A liquid storage tank is provided with an internal fixed support tube. Magnet-bearing liquid level and liquid density indicator floats are concentrically related to the fixed support tube externally thereof. Concentrically related, magnet-bearing indicator tubes are movably disposed within the fixed support tube and furnish liquid level and liquid density readout information when their respective magnets become magnetically latched with the float magnets.
