NOTE: Slling pipes are an excellent soluon for liquid level
applicaons where an unobstructed path to the target is not feasible
(see slling pipe mounng on page 9 for details).
• When mounng outdoors, it’s best to shade the sensor from direct
sunlight. Direct sunlight can warm the sensor housing above the ambient
temperature causing false temperature readings and overcompensaon by
the sensor.
• Installaon
Proper sensor mounng is crical for successful operaon of an ultrasonic
sensor. Using the following guidelines can help ensure trouble free installaon
and operaon:
• Ensure that the sensor face is perpendicular to the target surface. If the
target is more than a few degrees o perpendicular, it may not be
detected. Targets at greater distances will require more precise sensor
alignment.
• Mount the sensor in a locaon that provides an unobstructed column
of air from the sensor to the target. The required width of the air
column depends on several factors, including the angle and reecve
characteriscs of any potenal targets on the edge of the column, the
sensivity seng of the sensor, the maximum distance to the target, and
the reecve characteriscs of the target itself. Generally speaking a 3 to 4
foot diameter unobstructed column is sucient even at longer ranges.
