A sensing device for remotely reading the position of the needles of a gas
meter. The gas meter having a plurality of meter needles. The sensing
device including directional magnetic field emitters each having a north
and a south pole that are spaced from one another along a first pole axis
and a second pole axis, respectively. The magnetic emitters being secured
relative to respective needles such that the pole axes are perpendicular
to the respective needle axes. The emitters producing directional
magnetic fields that follows the position of the needles as they rotate.
The device further including position sensors positioned over the
emitters. The sensors reading the orientation of the respective magnetic
fields sending this information to a processor for calculating the
position of the first and second needles based on the orientation of the
respective magnetic fields. The device includes a transmitter for
transmitting the position of the needles to a remote location.
