3Physical Installation 
This chapter describes the necessary steps for proper installation of the 3DLevelScanner 
beginning with important pre-installation considerations such as environmental conditions, 
correct positioning and orientation, through the mounting and configuration process. 
3.1 Location and positioning guidelines 
Choosing the proper location to the 3DLevelScanner™should consider every aspect of 
the vessel and contained materials, including the silo or vessel dimensions, type of 
material and angle of repose, locations of filling and emptying points, maximum level of 
material, internal construction and moving part and any other consideration which may 
possibly affect the scanner performance. APM strongly recommends installing the 
3DLevelScanner according to the 3DScanner Locator PC software for properly choosing 
installation location and positioning. In case of no satisfying software solution, please 
contact APM Customer Support for assistance with the positioning. 
Moisture and water condensation 
Use the recommended cable gland and tighten the cable connection.For 
additional protection against moisture, lead the connection cable downward in 
front of the cable entry. Rain and condensation water can thus drain off. This 
applies mainly to mounting in areas where moisture is expected (e.g., by cleaning 
processes), or on cooled or heated vessels.
Measuring range 
The measuring range is set in the scanner and defined by silo dimensions and the full and 
empty calibration levels. These levels set the 100% and 0% values relatively. 
The scanner measurements are calibrated to the top of the 
body. If the scanner is lowered, or mounted with neck 
extension or head-body separation, it is important to adjust 
all measurements to the top of the body. 
NOTE: If the material level reaches the antenna, 
build up could form inside the horn over time and 
cause measurement errors or damage to the 
membranes. 
NOTE: the 3DLevelScanner™has a 500mm (20”) 
of dead zone (or blanking zone).
