The board allocates portions of memory to firmware (embedded
software in the monitor that can be upgraded remotely) and data storage.
The board also includes the monitor clock, random access memory
(RAM), and Flash. The monitor uses RAM while taking readings and
processing the flow data. The RAM then downloads the data to
NVRAM or non-volatile memory, which is backed up by an on-board
battery. Firmware programs concerning operation are stored in Flash.
