12. USonic-R™ with SmartGain™
A Patented Algorithm embedded in the system that:
Automatically ignores obstructions
Eliminates Beam angle concerns
Allows sensor to be recessed into nozzles to eliminate the dead zone concerns inside of vessel
Beam
Angle

13. USonic-R™ – SmartGain™
A 1” pipe (25 mm) can be as close as ½” (12 mm) from the centerline of the beam and ignored.
A 2” pipe (50 mm) can be as close as 1” (25 mm) from the centerline of the beam and ignored.
SmartGain is also a good choice for horizontal cylinders and spheres – to avoid possible multiple reflections.

14. SmartGain™ Comparison
Drexelbrook method:
Tank Mapping method:
Bulk mass of liquid reflects the greatest signal strength
USonic automatically attenuates receiver gain (based on actual distance to level) to only accept strongest signal reflections
Non-level reflections will not produce high enough signal strength to be identified & processed.
User must identify that non-level reflections are causing a problem – then enter a routine in the system to eliminate
Unit receives all signals from both level and non-level reflections
Unit adjusts Threshold level higher than reflections from non-level / base noise signals. Tank must be empty

15. SmartGain™ Comparison
Drexelbrook benefit:
Tank Mapping problems:
A problem would usually occur before the user would run routine, because…
The vessel must be emptied or near empty
Agitators, or any moving objects, must be run during programming
User must identify actual level then subtract 1.6 ft. (0.5m)
User could misadjust, causing level reflection to also be ignored
No user routines or programs
Vessel doesn’t need to be empty
User can’t misadjust or null out level signal reflection
Future obstructions will be ignored without user intervention, or reprogramming
