THE FORMULA

How the result is calculated

Runtime in hours = target water depth ÷ sprinkler application rate. The result is converted to minutes.

SproutScale preserves full precision while calculating and rounds only the displayed result or the final purchasable unit.

FIELD NOTES

Before you act

  • Measure application rate with several straight-sided cans.
  • Split long runtimes into cycles if water begins to run off.
  • Recheck the system after nozzle or pressure changes.
QUICK ANSWERS

Sprinkler runtime FAQ

How do I measure sprinkler rate?

Run the zone for a known time, average the depth collected in several cans, then convert that depth to inches per hour.

Why split irrigation into cycles?

Cycle-and-soak scheduling gives compacted or sloped soil time to absorb water.
