The WM-NLD series water meter might look a little complicated, but just a quick look at the Register tells you your consumption. And then, for a complete reading, the simple trick is to separate it into two distinct parts: The Register and The Dials.
The Register: The Big Picture Number
1. The Register in this example water meter displays — 1023 —
Translation: 102 thousand and 3 hundred U.S. Gallons, or: 102,300
Now, you could stop reading your meter here, because you know, at a general level, that the water meter reading is 102,300 gallons. And, to simplify, many landlords will only read the Register (to the nearest 100 gallons) because typically, consumption under 100 gallons isn’t that expensive.
2. However, since you’re probably NOT consuming by
the hundreds of thousands of gallons (or haven’t got there yet), you’ll
most likely focus on just the last few numbers on the Register,
depending on your rate of consumption. In this example, those last few
numbers are — 23 —
Translation: 2,300 U.S. Gallons.
The Dials: The Numbers for Those Placeholder Static Zeros
3. The Large Dial: As the red sweep hand on the Large
Dial moves from one number to the next number (e.g., 0 to 10), it’s
measuring 10 gallons, so one complete rotation equals 100 gallons. That
first static zero is the placeholder for the Large Dial number reading.
In this example (and remembering to round down) it is — 60 —
Translation: 60 U.S. Gallons, so your water meter reading is now at: 2,360 U.S. Gallons.
4. The Small Dial: As the red hand on the Small Dial
moves from one number to the next, it’s measuring one gallon, so one
complete rotation on the Small Dial measures ten gallons. In this
example, it is — 7 —
Translation: 7 U.S. Gallons, so your water meter reading is now at: 2,367 U.S. Gallons, and your TOTAL is: 102,367 U.S. Gallons.
So What’s My Rate of Consumption? The Final Tip: Simple Subtraction
To get your rate of water consumption between water meter readings: Take
your previous water meter reading, and subtract it from your most
current water meter reading.
