Measure the flow from the setup you actually use.

Fill a known container, time one to five trials, and calculate flow without guessing from hose size or water pressure. Keep the tested attachment and capture point visible with the result.

Formula and worked example

Flow = container volume ÷ average fill time × 60 seconds per minute.

For repeated trials, the tool averages the fill times before calculating flow. It also shows the difference between the fastest and slowest trials relative to the average.

Example

A 5 U.S. gallon container filled in 60 seconds measures 5 U.S. gallons per minute, approximately 18.93 litres per minute.

No hidden correction factor or automatic safety reduction is applied to the measured result.
