| The
sensor is installed on the tile line of the pool. The sensor is connected
to the control unit via a waterproof cable. The standard length of
the cable is 25 feet.
Water
enters the sensor chamber through the holes on the front and side
of the sensor. The system adds water to the pool until the water
reaches the "ideal" level on the sensor. If the system
has the "dump" function, water is removed from the pool
until the level is below the "ideal" level on the sensor.
The
system compares the electronic sensor outputs and determines which
are dry and which are wet, thus determining the water level. The
sensor is not affected by chemicals, water evaporation or water
residue.
The
sensor is not affected by temporary changes in pool water level
due to bather load or other temporary changes. Wave action due to
swimmers does not affect the sensor.
