Indoor water meters are typically read by a rotating gear assembly situated inside the meter enclosure. The gear assembly is driven by the rotation of the internal water meter shaft and transmits readings to an electrical output.
Outdoor water meters are typically read with a rotary arm and a mirror mounted on an electric motor. When the electric motor rotates the mirror, it sends an image of the sidewalk or garden below it to an output. You can easily find routine water meter leak identification services online from many sites.

Water meter leak detectors use a similar principle to determine if water is leaking from a meter. They consist of two parts: a transmitter and receiver. The transmitter is attached to the side of the meter that faces the street and sends an RF signal into the ground.
The receiver is placed close to where the leak is suspected and detects any return signal from the transmitter. If you have a water meter, it's important to keep an eye on it to make sure there are never any leaks. Water meter leak detectors can help you do just that.
When water flows through the meter, the detector detects the change in pressure and sends a signal to your computer or other device. If there is a leak, the detector will be more active than usual, and you'll be able to see the problem on your computer or other device.
