An  ultrasonic  sound  wave  is  pulsed  from  the  base  of  the  transducer.   The sound wave  reflects  against  the 
process medium below it.  The sound wave energy is returned to the transducer.  The microprocessor based 
electronics measures the time of flight between the sound pulse generation and its receipt.  This translates into 
the distance or range between the transducer and process media below. 
NEW FEATURES 
  Reflective Ultrasonic Technology 
  Simple configuration with push button or LVCN414-SW software configuration 
  Increased temperature range  
  Increased output filtering
