Irrigation Meter Calculator

Published before 2015

This app calculates the number of inches of water applied by irrigation over a given time. Begin by selecting the type of measurement unit used by your irrigation flow meter. The units are usually located just below the rolling numbers (like the odometer on your car).

Next, note the meter reading at the beginning of a time period (for example, when you turn the irrigation motor on) and at the end (for example, when the pivot has completed a circle). Enter only the numbers visible on the totalizer (rolling numbers, no decimals). If your meter totalizer has rolled over, you may need to enter a 1 in front of the ending reading to make the calculations work.

The app will calculate the amount of water applied to the given field over the given time period.
