Abstract
A system comprises a rod placed inside a tank and configured to move a pre-configured distance as the level of a gas stored in the tank changes. A chamber is positioned in relation to a top region of the tank. A magnet is coupled to an upper portion of the rod and disposed inside the chamber such that the magnet moves with the rod. A circuit board is positioned adjacent to the chamber and includes two sensors positioned along the length of the chamber, wherein each sensor generates a voltage signal corresponding to a strength of magnetic field associated with the magnet. A memory stores voltage values corresponding to the voltage signal and a processor coupled to the memory calculates a volume of the gas in liquid form in the tank based on a voltage value generated by at least one of the sensors.
