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.

A system includes a sensor and a computing system. The sensor is coupled to a syrup line of the beverage dispenser and is configured to measure a pressure within the line. The syrup line is coupled at a first end to a syrup bag and at a second end to a pump configured to pump syrup from the syrup bag to an outlet of the beverage dispenser. The pump is operated using pressurized gas and generates a pressure corresponding to the pressure of the gas within the syrup line when both the syrup bag is full and the outlet of the beverage dispenser is closed. The sensor transmits a measured pressure to the computing system. The computing system determines that the measured pressure is less than a threshold pressure. In response, the processor transmits an alert for display on a user device, which identifies the syrup bag for replacement.
