How To Read Your Water Meter
The Auburn Water District encourages customers to monitor their water use by reading their meter regularly. Most residential meters are located indoors, typically in a basement, crawlspace, or utility room near where the water line enters the home. Water meters measure usage in either cubic feet and function much like a car’s odometer. They display the total amount of water that has passed through the meter since it was installed. As water flows through the meter, internal components measure and record usage in cubic feet. Like any mechanical device, meters can wear over time and may eventually stop registering flow. However, a meter cannot record usage faster than the actual rate of water passing through it.
The District is in the process of upgrading its meter inventory, so customers may encounter several types of meter registers throughout the system. The newest meters being installed are the MACH 10 ultrasonic water meters. Because they have no moving parts, these meters provide consistent accuracy and reliable performance over their lifespan. They are also equipped with E-Coder® R900i™ technology, which includes advanced data-logging features to help monitor water usage patterns and quickly identify potential leaks.
Full instructions on how to read your MACH 10 R900i are available here.

Below is the E-Coder Register it activates when exposed to light. To read the display, simply shine a flashlight on the solar panel to “wake up” the screen. Full instructions on how to read your Neptune E-Coder® can be found here.

Below is the ProCoder Register that was installed for a short period of time within the District. In the example below, the reading is 2,852.52 cubic feet.

Below is the older T-10 Register previously installed in the District. In the example below, the reading is 38,785.64 cubic feet. The red triangle on the meter face is a low flow indicator and spins anytime water is passing through the meter.

You should record your meter reading at regular intervals (weekly or monthly), especially if you have an automated sprinkler system. Subtract the new meter reading from the previous reading to calculate your water consumption for the interval of days between readings. The MassDEP regulations state, averaged over a one year period, individuals should use no more than 65 gallons per day.
