Abstract: Embodiments of the present disclosure allow third-parties to collect data at a utility flow meter without substantial interference with the utility's ability to collect data for its own purposes. In an exemplary embodiment, a sub-meter interrupter is included that has a default position to allow for utility reading of a utility flow meter and a second position that allows for third-party reading of the utility flow meter. A third-party flow monitor or interrupter can also monitor attempted “reads” by the utility while the third-party flow monitor is reading the utility flow meter and can switch to the default (e.g., utility read setting) so as to allow the utility to conduct its read.
