A level monitoring system for a floating roof tank is provided. The level monitoring system includes a switch electrically connected to a monitor. When the tank reaches a high fill level, the switch closes an electrical circuit. The monitor senses that the circuit has become closed, indicating the high fill level, and sends a signal to an alarm module. The level monitoring system may use either a cable pull switch or a tilt switch that are activated by the floating roof of the tank when the a predetermined level has been reached.
