Abstract
A high-resolution index (HRI) detector module for use with a meter including an HRI wheel therein having a modulator thereon is provided. The HRI detector module includes a plurality of capacitive sensors positioned on a printed circuit board (PCB). The plurality of capacitive sensors is configured to detect a change in capacitance caused by the modulator of the HRI wheel when the modulator enters into an electric field generated by the plurality of capacitive sensors. Related systems are also provided.
