sensor increases. Additional false reflections may be generated which 

can influence the measuring result at close range.

If the medium has good reflective properties, VEGAPULS 62 with 

horn antenna can also be  mounted on a longer socket piece. Rec-

ommended values for socket heights are specified in the following 

illustration. You must carry out a false echo storage afterwards.
