Location and mounting information 
The compact one-piece construction of the IMP+ i.s. can be mounted easily 
using the integral nose thread (1.5" or 2" BSP/NPT, dependent on model).  
When choosing a location to mount the Imp, bear in mind the following: 
•  For  access  to  the  LCD  display  and  programming  buttons  it  is 
recommended  that  you  mount  it  in  an  area  which  is  easily 
accessible. 
•  The  ultrasonic  signal  path  should  be  free  of  falling  material  and 
obstructions such as pipes, beams etc.  
•  The IMP3 should be mounted at least 20cm (0.66 feet) above the 
maximum level of the material and be perpendicular to the surface. 
Whilst the IMP 6 and 10 should be mounted at least 30cm (0.98 
feet) above the maximum level of the material and be perpendicular 
to the surface. 
•  The ambient temperature is between -20ºC and 65ºC.  
•  There should be no high voltage cables or electrical inverters close 
by.
