Water meter reading doesn't have to be complicated. The first thing you need to do is locate your water meter. You might be surprised to know that it's actually in your house. Check your basement near your furnace or hot water heater. In Canada, most water meters are installed indoors to reduce the risk of pipe freezing and damage.
Once you've found your water meter the second thing you need to do is identify what type of meter it is. Sensus, Neptune, Elster, and Badger are just some of the manufacturers of water meters but there are also lots of different models with different components.
Water meters tend to differ in the following ways:
1. Sweep hand
2. Low flow indicator
3. Odometer and unit of measurement
Click on the image that most closely matches your water meter and learn how to read your meter.
182.470 m³ (cubic meters).
Note that the reading is not 182.471 cubic meters because the number 0 in the last position (read the odometer from left to right) is still visible. For almost all water meters, you use the smallest number visible in the last position of the odometer for your reading.
The red circle thing in the corner is called a low flow indicator. This is also in the shape of a triangle on many other water meters.
The low flow indicator turns when water is flowing through the meter. It can also tell you if you have a leak.
301.192 m³ (cubic meters)
The numbers 301 in the reading 301.192 are pretty easy to understand but the .192 part of the reading might be a little confusing. These numbers come from understanding how to combine the sweep hand reading with the odometer reading.
The red number in the odometer counts the first decimal position which is the tens decimal position, 0.1 in this case. And the sweep hand counts the hundreds and the thousands decimal positions, in this case 0.092.
Even though you see a red number 2 on the odometer, the correct reading is not 301.292. Why? Because the red number 1 is the smallest number visible. You always count the smallest number visible in the tens decimal position.
The big red sweep hand is pointing to a line that is just after 0,09. In fact it's two lines after 0,09. So, that's 0,092. Because the red number in the odometer is .1 you add that to .092 and get 0.192
Also note that there is a black circle thing just left and below the centre of the face of the water meter. This is called a low flow indicator.
A low flow indicator spins when any water flows through the meter. It can be used to tell if there is a leak in your home or property.
8.3 gal (gallons)
Unlike most water meters in Canada, the unit of measurement for this meter is in gallons not cubic meters.
The large sweep hand is pointing to a line just past the number 8. It's actually 3 lines after the number 8 which means it is 8.3 gallons.
You can also see that there is a permanent blue 0 printed to the right of the odometer. This means that the white number 1 is in the tens position.
In this case, you can ignore the white number 1 on the odometer. Although it looks like it is 1, it is actually 0 because you always use the smallest number displayed on the odometer and you can still see the bottom of the number 0 in the tens position on the odometer.
7734.042 m³ (cubic meters)
The 7734 part of the reading is simple enough but you might get tripped up on the .042 part. These numbers come from combining the numbers on the small sweep hand with the white number with the black background in the odometer reading.
The white number in the odometer counts the first decimal position which is the tens decimal position, 0.0 in this case. And the small sweep hand counts the hundreds and the thousands decimal positions, in this case 0.042.
Even though you see the top part of a white number 1 on the odometer, the correct reading is not 7734.142. Why? Because the white number 0 is the smallest number visible. You always count the smallest number visible for the numbers on the odometer that turn slowly and don't click to the next number.
The small red sweep hand is pointing to a line that is just after 4. In fact it's two lines after 4. So, that's 0.042. Because the white number in the odometer is .0 you add that to .042 and get 0.042.
Blessed be the digital meters for they give intuitive water usage readings.
For digital models there is an icon such as a + sign that appears when water is being used. This is called a low flow indicator. A low flow indicator can be used to see if your home has a leak.
If you've got a water meter that isn't on this list, take a clear picture of it and send it in an email to firstname.lastname@example.org and we'll help you read your meter.
Also, when you purchase your Flowie water sensor, we read your water meter so you don't have to.
Now that you've been equipped with the awesome ability to read your water meter, remember, with great power come great responsibility.
Be water rich, my friends.
