About the 
Ultra Twin
 
Ultra  Twin  has  two  independent  points  of  measurement,  the  wallmount 
model provides a dedicated display to each point of measurement, whilst the 
fascia model, whilst in RUN, will show detail of one point of measurement 
in  the  main  display  line,  with  the  second  point  being  displayed  on  the 
auxillary display line. In both models the display will provide information 
relevant  to  the  point  of  measurement  selected  whilst  in  RUN  and 
PROGRAM mode. 
 
Ultra  Twin  combines  premium  specification  with  high  performance  in  a 
most  versatile  system  which  is  quickly  configurable  offering  a  choice  of 
applications in any combination, between the two points of measurement, of 
three specific applications i.e. level or volume measurement, pump control 
or flow measurement.  
Functional Description 
Ultra  Twin  sends  a  transmit  pulse  to  the  transducer(s),  which  emits  an 
ultrasonic pulse perpendicular to the transducer face, and the returned echo 
is  sent  back  to  the  Ultra  Twin.  The  time  taken  to  receive  the  echo  is 
measured  and  the  distance  from  the  transducer  face  to  the  surface  being 
monitored is calculated.
