P703 Minimum Head 
This parameter is used to enter the distance, above empty, that represents 
zero  head  and  flow.  This  feature  is  used  in  Primary  Measuring  Devices 
where the zero reference is at a higher level than the channel bottom, at the 
point of measure.  Enter distance in Measurement Units P104. 
P704 Maximum Head 
Enter the head value that represents maximum flow, enter in Measurement 
Units P104.  
Note any change to  the  value of this parameter  will be  reflected  in P106 
(Span) and vice versa. 
P705 Maximum Flow 
When  P702  =  2  Ratiometric  enter  the  flow  rate  value  that  occurs  at 
maximum  head  (P704),  enter  in  volume  units  (P706)  per  time  units 
(P707).  
When  P702  =  1  Absolute,  and  all  relevant  flow  parameters  have  been 
entered, the  maximum flow that occurs at maximum head P704 will be 
calculated,  after  the  unit  is  returned  to  RUN  mode,  and  displayed in  this 
parameter in volume units (P706) per time units (P707).
