A protection domain system is implemented to provide protection for applications executing in a computing environment. In this way, a drop, that is, a notch portion, in the frequency characteristic causing deterioration of the gain can be eliminated. Meter usage data is obtained by the collector from the meter sensor, date and time stamped, and stored in the collector until directly transmitted to the control center or a substation if within range and not blocked or impeded by a physical structure or other obstacle. In one embodiment this may promote speculative invalidation. The measuring section characterizes a parameter of the fluid flow.
