Metercam
The Metercam is used with an electromechanical meter (rotating disk). It is a digital
disk sensor without the many drawbacks found on usual photoelectric sensors, such
as difficulty to align properly and sensitivity to light. With the Metercam, no
alignment is necessary since it detects and picks up the disk by itself. Another feature
is its electronic shutter that makes it insensitive to light variations including bright
sunlight.
The Metercam is built around a miniature digital camera with a ½" field view
combined with a RISC processor that detects the position of the meter disk and locks
automatically on the reference point (black flag).
The Metercam is mounted on four suction cups installed directly on its backside.
For a good and lengthy hold, lightly wet the inside of the suction cups, especially
when field testing in colder weather. Also, keep the inside of the suction cups clean.

Note: For electromechanical meters with a hidden disk, a side-mount Metercam is
available.
