Zero Head
The distance above 2.2.4. Empty, in 2.1.1. Units representing zero head (and zero
flow).
Index
Values
This feature can be used for most weirs and some flumes (e.g. Palmer-Bowlus)
where the zero reference is at a higher elevation than the channel bottom
Maximum Flow
The maximum flowrate associated with 2.13.4.2. Maximum Head.
Index
Values
This represents the flow at the highest head level supported by the PMD and works
in conjunction with
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
The limitation of four digits is for the LCD only, and the flowrate value is available
with greater precision through communications.
Notes:
• The display of the measured value is limited to six digits. A Maximum Flow
value larger than seven characters will not display correctly.
• If measured value is larger than seven characters, the screen displays ####. A
