For over a century, water meters most commonly operated according to mechanical principles – the flow of water through the mechanism turned a nutating disc (see the sidebar on page 31), oscillating piston, turbine rotor, and other mechanical parts that measured the volume of water passing through the meter. When solid state electronic technology allowed for encoder registers to operate electronically, the stage was set for a similar revolution (or, in a real sense, a lack of revolutions) in the meter itself.
