Not sure if LandFX can help with this, but I'm also hoping someone can point me somewhere to figure this out.
I have a huge site with 403 control valves across 26 meters and smart controllers (some installed, some pending). The City wants to know what our lowest maximum flow across all these meters would be so they can do their water modeling and fire flow calcs. Using flow sensors, central control, and flow management capabilities to keep flows within a set limit is the obvious way to do this, but we don't have that equipment, and the City isn't forthcoming on what our maximum flow can be.
So, has anyone dealt with this before? Is there software somewhere? Can LandFX do this somehow?
Thanks for the help!

Tom,
I am not sure I follow, however, I take this as you needing to know what the lowest demand for each Meter is going to be based on your design, correct? Or are you saying the system has been installed and they are now requiring actual numbers based on what was put in (and the sensors were not a part of the design/installation)?
If they are needing numbers based on your design, why don't you run a valve schedule and send to Excel. This way you can filter and sort things further to what they are looking for. I would even say running a watering schedule could get you further usage numbers.
Feel free to expand on this and we can see if there are any other methods to get the results you are looking for.

Well, I took an "easy" way out. I generated a single schedule for all POCs, and took an average for the flows per valve.
What the city is asking for is some idea of what the lowest possible high flow situation would be. In other words, not all of the highest flow zones running at the same time, but some combination of zones, that, while maybe a "high" flow, is not as high as the combination of all the highest flow zones. The obvious, nearly impossible part, is to figure out this scheduling across 26 meters, and 26 smart controllers that water in response to on-site weather data (SmartLine controllers with weather sensors). Not to mention, several hydrozones.
So taking this average flow and multiplying by 26 (or 13, if we set odd/even day restrictions) would give us an average high flow, not as high as that highest theoretical maximum.
The flow management capabilities of Rain Bird's LXD-IQ system would figure this out automatically, but only if we know what that maximum allowable flow would be. But that's irrelevant, since we won't be changing out controllers and flow sensors. I don't think Weathermatic has this capability.
