Can I use an average flow?

Yes. Use a time-weighted average over the entered flowing period. Separate periods when water is off.

Does the allowance set a safe rinse flow?

No. It is a volume budget. Verify rinse performance and the approved process before changing flow.

Only if the entered price includes it on the same cubic-meter basis. Otherwise add treatment and discharge expense separately.

It is the constant flow that exactly uses the entered volume allowance over the entered hours. It does not establish adequate rinse quality.

Calculate water use from measured rinse flow and actual flowing time. Compare the volume with an entered allowance and estimate its supply expense.

Calculate flowing rinse water volume and expense, then compare use with an entered period allowance.

Best suited to period rinse water budgets, measured flow comparisons.
Does not determine required rinse concentration or cleanliness. Excludes treatment and discharge costs unless included in the price.
