I have a question regarding Darwin Calibrator and assigning these customer meters to Hydrants. If one was to do this, does Darwin Calibrator ignore those demands assigned to the hydrants?

I just want to make sure the model is accounting for the customer meter demands assigned to the hydrants. Since you can only view the junction demands within Darwin Calibrator I wasn't sure whether or not they were accounted for. Is there a way to confirm that they are accounted for? Using Watercad V8i SS5 (08.11.05.61)
You can compare the flow results in the simulated results tab of calibrator. Try changing the demand of customer element assigned to your hydrant, with that changed the Simulated flow also will change, this way you can confirm it.
Make sure that you are recomputing the model and the calibrator run as well to see the changed flow.

Here's a small test model to prove it (created in SELECTseries 5 with the latest cumulative patch set). The simulated flow in the single pipe matches the demands from customer meters placed on a hydrant.

ok, I noticed you input pipe P-1 as an observed snapshot.... is this typical or just a method of verifying the customer meter demands?
When doing fire flows tests to use as snapshots I input the following:
Observed Targets
Boundary Overrides
Demand Adjustments
Is this the correct way I should be inputting my observed data?
