How Do I Read Assured Automation WM-PC Series (size 1½”) Water Meter in U.S. Gallons?

Posted by Michelle Farrell on 29th Dec 2017

This Assured Automation WM-PC Series (size 1½ inch) water meter (and submeter) is slightly different than its smaller size counterparts, but like the other sizes in this series, it’s easy to read, once you know the trick: Think of it in two main parts — The Register and The Dials

How to read a WM-PC water meter

The Register: The Big Picture Number

1. The Register in this example water meter displays — 043679 —
Translation: 4 million, 367 thousand, and 9 hundred U.S. Gallons, or: 4,367,900.0

Now, you could stop reading your meter here, because you know, at a very general level, that the water meter reading is 4,367,900 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 millions 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 — 79 —
Translation: 7,900 U.S. Gallons.

The Dials: The Nitty-Gritty, Bottom Line Numbers
3. Moving clockwise from the Register, read each Dial number, and tack that number on, after the last few numbers (79) on the Register. In this example, it’s — 1 —
Translation: 10 U.S. Gallons, so your water meter reading is now at: 7,910 U.S. Gallons.

4. Keep moving clockwise and tacking on the next number. Notice the rule-of-thumb of
rounding down (for example, if the red dial is on 5-1/2, round down to 5). In this example, the next dial number to tack on is — 5 —
Translation: 5 U.S. gallons, so your water meter reading is now at: 7,915 U.S. Gallons.

5. If you’re reading this far, you’re into a super accurate water meter reading, down to the sub-gallon! Note the Decimal Point, which helps you to keep track of where those numbers need to go. So, in this example, continuing to move clockwise, the last dial number is — 0 —
Translation: (Decimal Point) .0 U.S. Gallon, so your water meter reading is now at:
7,915.0 U.S. Gallons, which gives you your TOTAL of: 4,367,915.0 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.
