GAS LEAKAGE MONITORING SYSTEM

Abstract:

Various methods and apparatuses are provided for monitoring and detecting gas leaks. A method of determining a gas leak with a sensor assembly is provided. The sensor assembly includes a primary sensing device and a reference sensing device. The method includes receiving, via the primary sensing device, a first oxygen concentration level reading of a given area. The method also includes receiving, via the reference sensing device, a second oxygen concentration level reading of the given area. The method further includes comparing the first oxygen concentration level reading and the second oxygen concentration level reading. Based on the comparison, the method still further includes causing a transmission of a signal that a gas leak is occurring in an instance in which the first oxygen concentration level reading and the second oxygen concentration level reading have a difference greater than a threshold difference. A corresponding gas detection apparatus is also provided.
