The majority of our meters are Neptune T-10 water meters and they have a straightforward face, and just a quick look at the Register tells you your consumption. The face has two distinct parts: The Register and The Dial.
The Register: The Big Picture Number
1. The Register in this example water meter displays — 1023670 —
Translation: 1 million, 23 thousand, 6 hundred and 70 U.S. Gallons, or: 1,023,670
Now, you could stop reading your meter here, because you know, at a general level, that the water meter reading is 1,023,670 gallons.
The Dial: The Number of Single-Digit Gallons for That Static Zero
2. As the red sweep hand on the Dial moves from one number to the next number (e.g., 0 to 1), it’s measuring one gallon, so one complete rotation equals 10 gallons. That static zero is the placeholder for the dial number reading, so replace the static zero with the red Dial number, remembering to round down. In this example it is — 4 —
Translation: 4 U.S. Gallons, so your water meter reading is now at: 1,023,674 Gallons.
If you want to check for leaks, you should turn off the water to your house, then observe your water meter and if the triangle indicator is slowly rotating that indicates that water is flowing.
