Discover Guide: How To Read A Water Meter
Reading your water meter is a simple but important skill for tracking water usage and detecting potential leaks. If your meter is set up so that each main number represents 1,000, 100, or 10 units (Gallons, Cubic Feet (CF), Liters), you will need to read both the main numbers and the smaller dials for an accurate reading.
How do I know what type of meter I have?
On the face of your meter, you will see the main numbers display and to the right side of them, there will be a number displayed as x1000, x100, or x10.
Click the number of your meter type below to begin.
There is a visual walk-through at the end of Step 3 for each meter type.
X1000 Unit Meters
Step 1: Read the Main Numbers
The main display on your water meter shows the total water used in 1,000-Gallon/CF/Liter increments. This example uses Gallons as the unit.
Look to the right side of the main numbers display and you will find the multiplier indicated as X1000. This tells us the main number (310) needs to be multiplied by 1000 to give us the proper reading.
- Example: If the main display reads 310, this means 310,000 gallons have been recorded since the meter was manufactured.
- Let's start by writing the number as 310,XXX.X and we will fill in the X's as we follow the steps below.
Step 2: Read the Smaller Dials
Below or near the main numbers, you will see small dials labeled x100, x10, x1, and x0.1. These show water usage in smaller increments.
Each dial has a needle pointing to numbers 0-9. If the needle is between two numbers, record the lower number, the same way you would read an analog clock.
When reading a water meter, one common question arises: “The dial looks like it's pointing directly at a whole number, but not quite—how do I know for sure?” The key to accurate reading is checking the next lowest dial. Each dial moves sequentially, so if the x10 dial appears to be right on the 4, you need to check the x1 dial. If the x1 dial has passed 0, then the x10 dial has indeed reached 4. However, if the x1 dial is still before 0—for example, at 8—it means it hasn’t completed a full rotation yet. In this case, the x10 dial is still a 3, not a 4. Understanding this small but crucial detail helps avoid misreading your water usage and ensures accurate meter readings.
1. Read the x100 Dial
- This represents hundreds of gallons.
- If the needle is pointing at 1, this means 100 gallons.
- Our reading is now represented as 301,1XX.X
2. Read the x10 Dial
- This represents tens of gallons.
- If the needle is pointing at 1, this means 10 gallons.
- Our reading is now represented as 301,11X.X
3. Read the x1 Dial
- This represents single gallons.
- If the needle is pointing at 4, this means 4 gallons.
- Our reading is now represented as 301,114.X
4. Read the x0.1 Dial
- This represents tenths of a gallon and helps detect small leaks.
- If the needle is pointing at 2, this means 0.2 gallons.
- Our reading is now represented as 301,114.2
Step 3: Combine the Readings
Now, combine all the values together for a full reading.
- Main display: 310 (310,000 gallons)
- x100 dial: 1 (100 gallons)
- x10 dial: 1 (10 gallons)
- x1 dial: 4 (4 gallons)
- x0.1 dial: 2 (0.2 gallons)
Your full meter reading is:
310,114.2 gallons

X100 Unit Meters
Step 1: Read the Main Numbers
In this example, the main display on your water meter shows the total water used in 100-Gallon/CF/Liter increments. This example uses Gallons as the unit.
Look to the right side of the main numbers display and you will find the multiplier indicated as X100. This tells us the main number (250) needs to be multiplied by 100 to give us the proper reading.
- Example: If the main display reads 250, this means 25,000 gallons have been recorded since the meter was manufactured.
- Let's start by writing the number as 25,0XX.XX and we will fill in the X's as we follow the steps below.
Step 2: Read the Smaller Dials
Below or near the main numbers, you will see small dials labeled x10, x1, x0.1, and x0.01. These dials allow for a more precise reading.
Each dial has a needle pointing to numbers 0-9. Some dials move clockwise, while others move counterclockwise. If the needle is between two numbers, always record the lower number.

- This represents tens of gallons.
- If the needle is pointing at 7, this means 70 gallons.
- Our reading is now represented as 25,07X.XX
2. Read the x1 Dial
- This represents single gallons.
- If the needle is pointing at 2, this means 2 gallons.
- Our reading is now represented as 25,072.XX
3. Read the x0.1 Dial
- This represents tenths of a gallon (0.1 gallons).
- If the needle is pointing at 7, this means 0.7 gallons.
- Our reading is now represented as 25,072.7X
4. Read the x0.01 Dial
- This represents hundredths of a gallon (0.01 gallons).
- If the needle is pointing at 2, this means 0.02 gallons.
- Our reading is now represented as 25,072.72
Step 3: Combine the Readings
Now, combine all the values together for a full reading.
- Main display: 250 (25,000 gallons)
- x10 dial: 7 (70 gallons)
- x1 dial: 2 (2 gallons)
- x0.1 dial: 7 (0.7 gallons)

The main display on your water meter shows the total water used in 10-Gallon/CF/Liter increments. This example uses Cubic Feet (CF) as the unit.
Look to the right side of the main numbers display and you will find the multiplier indicated as X10. This tells us the main number (745) needs to be multiplied by 10 to give us the proper reading.
- Example: If the main display reads 745, this means 7,450 cubic feet have been recorded since the meter was manufactured.
- Let's start by writing the number as 7,45X.XXX and we will fill in the X's as we follow the steps below.
Step 2: Read the Smaller Dials
Below or near the main numbers, you will see small dials labeled x1, x0.1, x0.01, and x0.001. These dials allow for a more precise reading.

Final Tips
✔ Always record the lower number if a needle is between two numbers.
✔ Check your meter regularly to monitor your usage.
✔ If the x0.001 or x0.01 dial moves when no water is in use, you may have a small leak.
By following these steps, you can accurately read your water meter and stay in control of your water usage!
Why is One of the Numbers on My Water Meter Red?
If you've noticed a red digit on your water meter, you might be wondering what it means. According to ISO standards (which apply internationally but not in the U.S.), any digit representing a measurement of less than 1,000 liters (about 100 gallons) is required to be red. While the AWWA (American Water Works Association) does not have this requirement, many manufacturers use the same registers worldwide to simplify production. As a result, U.S. water meters often include a red digit—even though it serves no specific purpose for American users.
