| 20090255346 | Encoder-type register for an automatic water meter reader - An encoder-type register for an automatic meter reader to be interfaced with a visual read-only register of the kind found in a water meter that measures water consumption. The water meter register has a rotatable sweep hand that carries a magnet and rotates around a register plate in relation to the speed and volume of water moving through the water meter. A plurality of (e.g., three) magnetic (e.g., Hall effect) sensors are fixedly positioned one-after-another in the path of the magnet carried by the rotating sweep hand. The magnetic sensors measure the magnetic field produced by the rotating magnet and generate corresponding output signals. A microprocessor receives the output signals generated by the magnetic sensors whenever the magnet rotates therepast. The microprocessor stores information concerning the number of rotations of the magnet carried by the sweep hand depending upon the direction in which the magnet is being rotated as an indication of water consumption. The microprocessor provides the stored information to a meter interface unit connected to a set of output terminals of the encoder register so that such information can be transmitted from the meter interface unit to a remote data collector over a wireless communication path. | 10-15-2009 |
