SR50A Sonic Ranging Sensor

4.2 Mounting Height
Any target to the SR50A should be at least 50 cm or more from the face of the
transducer. An attempt should also be made to not mount the sensor too far
from the target surface. The further the sensor is from the target the more the
absolute error increases. If your application is measuring snow depth in an
area that will likely not exceed 1.25 meters of snow then a good height to
mount the sensor would be 1.75 to 2.0 meters. Mounting the sensor 4 meters
above the ground will result in the potential for larger snow depth errors.
4.2.1 Reference Point
The front grill on the ultrasonic transducer is used for the reference for the
distance values. Because it is difficult to measure from the grill one can use
the outer edge of the plastic transducer housing see FIGURE 3. If this edge is
used, simply add 8mm to the measured distance.

4.3 Mounting Options
There are two standard mounting options available for the SR50A sensor.
The first is the SR50A Mounting Kit, part number 19517. This bracket is used
to mount the SR50A to a CM206 crossarm or a pipe with a 1” to 1.75” OD.
