Water Meters

How Does a Residential Meter Register Water Usage?

The domestic residential water meters used by the Town contain a nutating disc to measure volume of water used.  A disc is attached at an angle to a ball within the body of the water meter.  When water passes through the meter, the disc is caused to wobble (or “nutate”) which causes the disc and the ball to rotate.  A needle is mounted to the ball, which is driven by the nutating motion of the disc.  A full rotation of the needle measures a fixed volume of water.  In turn, the needle drives a shaft, which registers water usage.  Active usage is displayed by the spinning of a small red needle (low flow) and by a rotating dial gauge (normal or high flow).  If your needle or dial gauge is spinning, this can only be caused by water passing through your meter.  If your small red needle is spinning and all of your taps are turned off – you have a leak!
