Universal calculation support
When the Primary Measuring Device (PMD) doesn’t fit one of the standard types, it can be
programmed using a universal characterization. When Primary Measuring Device (2.13.2.)
(Page 240) = Universal, then the head/flow breakpoints must be entered into Universal Head
vs. Flow (2.13.6.) (Page 247)
Two curve types are supported:
●
Universal Linear Flow Calculation (Page 240) (piece wise linear)
●
Universal Curved Flow Calculation (Page 240) (cubic spline)
Both are shown in the following chart.

Head
Characterization is achieved by entering Head 1 (2.13.6.1.1.) (Page 247) and its
corresponding Flow 1 (2.13.6.1.2.) (Page 248), either from empirical measurement or from
the manufacturer's specification.
●
Increasing the number of defined breakpoints will increase the accuracy of the flow
measurement.
●
Breakpoints should be concentrated in areas exhibiting the higher degrees of nonlinear
flow. A maximum of 32 breakpoints can be defined.
●
For Universal Linear Flow Calculation, Maximum Head and Maximum Flow must be
entered as breakpoints.
●
For Universal Curved Flow Calculation, values in Maximum Head (2.13.4.2.), Maximum
Flow (2.13.4.3.) are automatically used.
