Zero head (2.13.4.5.) (Page 244)
This represents the highest head level supported by the PMD and works in conjunction with
Maximum Flow (2.13.4.3.) (Page 243) to define the highest point in the exponential curve.
Use it when the PMD requires a maximum head and flow reference point. This would include
Exponential, Palmer-Bowlus Flume, H-Flume, and Universal breakpoints.
Maximum flow (2.13.4.3.)
Sets the maximum flowrate associated with Maximum Head (2.13.4.2.) (Page 243).

Flow (3.2.8.14.) (Page 259)
This represents the flow at the highest head level supported by the PMD and works in
conjunction with Maximum Head (2.13.4.2.) (Page 243) to define the highest point in the
exponential curve. Use it when the PMD requires a maximum head and flow reference point.
This would include Exponential, Palmer-Bowlus Flume, H-Flume, and Universal breakpoints.
Also, use this parameter with Flow Time Units (2.13.4.4.) (Page 244) to define the flow rate
units.
Note
•
The display of the measured value is limited to seven characters. A Maximum Flow value
larger than seven characters will not display correctly.
•
If measured value is larger than seven characters, the screen displays ####. A larger unit
[Flow Time Units (2.13.4.4.) (Page 244)] should be used, or number of decimal points
[Flowrate Decimal (2.13.4.6.) (Page 245)] should be reduced.
