Optically readable and human readable dial |
摘要 |
A utility meter reading system permits reading a meter with a noncontact shaft angle detector and simultaneous visual inspection of the dials of the meter from a laterally spaced viewing position. Each of the dials defines a patterned disc for concentric rotation with the shaft and a beveled circumferential surface which extends around the patterned disc and bears a plurality of numerical indicia. The dials are configured to be adhesively mounted over dial pointers on an existing utility meter, thus permitting retrofitting of meters with noncontact shaft angle detectors.
