Flume will work in apartment buildings and multi-family homes as long as:
There is one water meter per unit.
The water meter is compatible with Flume. To check meter compatibility click HERE.
If multiple units share one compatible water meter, Flume will still work. However, Flume will be unable to differentiate what unit, apartment, or building the water is coming from. Because Flume records water usage directly from the water meter, your Flume will report ALL the usage that is reported by the water meter (regardless of how many units are connected to the meter). Additionally, Detail+ is not compatible with homes that have multiple units on a single water meter.
