Mounting instructions

Mount the device with the ultrasonic sensor (horn) facing toward the target.

The sensor's greatest sensitivity is in the center of the measurement beam (a diffuse cone of ultrasonic waves). However, objects outside the cone can also cause reflections of the sound waves and thus interfere with the measurement. Especially objects with sharp corners and objects closer than the target can cause strong reflections which might drown the reflections of the target.

Some recommendations for positioning the device:

• Make sure that the target is in the center of the measurement beam.
  
• Try to keep any interfering objects away from the measurement beam.
  
• Avoid objects which could cause interference, e.g. objects with sharp corners.
  
• Mount the device on a cantilever to stay away from mounting poles, walls or tubes.
  
• Schedule some time for finding the best position by experiments.
