DIVER MATIC (Water Level Meter)

portable signalling
apparatus, visual and acoustic, for the gauging
of the water level.
DIVER/MATIC is equipped of a metric cable,
number by a 0-200 m scale and roll up cable
with bracket.
For its working and power supply it is enough
a standard 9 Vcc pile, included with the device.
Thanks to the indelible marked metric
numeration on the cable sheath, it is possible
to read the distance from the water surface by
means of the bipolar probe, which provides to
turn on a LED and its relative acoustic signal.
