Typical Flow Characterization
Characterization is achieved by entering the head ( P610 ) and corresponding
flow ( P611 ), either from empirical measurement or from the manufacturer’s
specification. The more breakpoints that are defined, the more accurate will
be the flow measurement. Breakpoints should be concentrated in areas
exhibiting the higher degrees of non linear flow. A maximum of eleven
breakpoints can be defined.
P610 (G) HEAD BREAKPOINTS
Enter the head breakpoints
* for which flowrate is known.
values: 0.000 to 9999
P611 (G) BREAKPOINT FLOWRATES
Enter the flowrate
* corresponding to each Head Breakpoint entered.
values: 0.000 to 9999
* To enter a Head or Flowrate Breakpoint . . .
Enter the desired value
Scroll ( or ) or direct
access the desired breakpoint.
