When installing the sensor,
make sure that the sensor
is oriented relative to the
water flow as shown in the
illustration. Otherwise,
suspended matter in the
water will adhere to the
detection surface and affect
the measurement value.
Do not install the sensor with
the sensor surface facing
down. Bubbles may
accumulate in the
measurement area, or the
measurement light may be
reflected off the bottom of
the facility or accumulated
objects, making it impossible
to measure correctly.
Water flow
Do not install the sensor
near a wall or other
surface. Measurement light
will strike the surface and
the reflected light will affect
the measurement values.
Install the sensor avoiding
the situation that the
sensor surface receive
strong light such as
sunlight directly.
