Gas monitoring and alarm systems and methods including level indicator unit

A method for monitoring gas levels and triggering an alarm system, the method comprising:

• providing a monitor and a sensor coupled to the monitor, the sensor configured to sense a concentration of a gas in an area and send data about the concentration of the gas to the monitor;
• receiving, by the monitor, the data about the concentration of the gas in the area from the sensor,
• triggering, by the monitor, an alarm status when the concentration of gas in the area exceeds a predefined alarm threshold;
• providing a level indicator unit coupled to at least one of a gas storage tank and a shut-off solenoid of a gas monitoring and alarm system and incorporated into the monitor comprising a display screen adapted to display information about the at least one of the gas storage tank and gas monitoring and alarm system, a plurality of light indicators adapted to be visual indicators of a gas level of the at least one of the gas storage tank and gas monitoring and alarm system;
• control logic adapted to receive information and performing operations of the level indicator unit, and management software coupled to the control logic to manage the operations of the level indicator unit;
• and
• coupling management software to the control logic and managing operations of the level indicator unit.
