Alternate calibration approach*
23
1. This approach requires access to the
register on the top of your existing
water meter and ability to convert units
shown to gallons or liters
2. Make note of starting meter value on
water meter. Taking a photo may help
3. Using a faucet, in your home or
business, press the Start button and
then turn on the faucet
4. Looking at the elapsed time field, allow
water to flow for two minutes
5. Return to your water meter. Subtract your starting meter
value from your ending meter value, and enter this amount
(in gallons) into the Actual Gallons field and click Recalibrate
6. The calibration process is now complete. If an error was
made, please repeat this process
*This procedure is typically used in large buildings (multi-family, commercial, etc.) where
it is not possible to ensure that there is no flow after the meter.
