A sensing device arrangement for a fuel storage system is provided having at least one storage tank, a plurality of sensing devices positioned in or around the at least one storage tank, and a controller in electrical communication with the plurality of sensing devices. After heating to a temper temperature, the magnetic material is cooled in a cooling liquid within a cooling chamber into which a pressurized cooling gas is introduced. The system also includes a controller configured to communicate with the reader device and compile the identification information received from the reader device and the locations of the identification devices to maintain an inventory of the components. The bracket defines a space adjacent the second end.
