There are several ways to read a water meter, including:
Direct reading
Remote reading, which is accomplished via an electronic signal using a wire, where anyone can read directly or touch.
Touch read or plug-in reading that employs a handheld device that receives an electronic signal by touching a remote station or plug-in. The signal is then translated into readings that are stored in the handheld device.
Automatic meter reading, in which the meter reader receives readings via radio transmission.
