2.15.3.3. Maximum Head
The maximum level value associated with the PMD and works in
conjunction with 2.15.3.4.Maximum Flow at 20 mA for Ratiometric
calculations. (Defined in 2.1.1.Units.)
This represents the highest head level supported by the Primary
Measuring Device (PMD) and works in conjunction with
2.15.3.4.Maximum
Flow at 20 mA
to define the highest point in the exponential curve. Use it
when the PMD requires a maximum head and flow reference point.
Maximum Head must be set for all Absolute and Ratiometic PMDs.
2.15.3.4. Maximum Flow at 20 mA
The maximum flowrate associated with 2.15.3.3.Maximum Head shown in
2.15.3.7.Flowrate Units.
This represents the flow at the highest head level supported by the
Primary Measuring Device (PMD) and works in conjunction with
2.15.3.3.Maximum Head
to define the highest point in the exponential
curve. Use it when the PMD requires a maximum head and flow reference
point. Maximum Flow must be set for all Absolute and Ratiometic PMDs.
Values
Range: 0.000 to 60.000
Default: 60.000
Note:
• The display of the measured value is limited to 7 Characters. Setting a
Maximum Flow value larger than 7 characters will not display
correctly.
• If measured value is larger than 7 characters, #### will be displayed. A
larger unit (
2.15.3.7.Flowrate Units
) should be used, or number of
decimal points (
2.15.3.6.Flowrate Decimal
) should be reduced.
Values
Range: 0 to 9999999
Default: 100
