BACKGROUND – HOW IT WORKS
The Well Watch works by pushing an air pressure wave or low frequency sound wave
into the well. For this reason, it is important that the probe be connected to a closed
end of the pipe to prevent the air pressure from just escaping the open end. After the
Well Watch sends its sound pulse, it listens for the pulse to return. And since sound
travels at a predictable rate, it can tell where in the well the pulse was reflected by
timing the returning pulse.

Well Watch sends its sound pulse, it listens for the pulse to return. And since sound
travels at a predictable rate, it can tell where in the well the pulse was reflected by
timing the returning pulse.
The pressure wave generated by the probe will continue to travel into the well until
something disturbs it. Every imperfection in the well will disturb the wave, and every
time it is disturbed, some of the wave changes direction and is reflected back to the
Well Watch leaving the main wave a little weaker. A complete obstruction like the
surface of the water, reflects the entire remaining wave. Most common obstructions like
wires and tubes and pipe couplings do not reflect enough of the wave to cause a
problem, provided that the remaining part of the main wave is relatively big enough to
be obviously the one of interest.
