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 Universal is selected as the
PMD type (P600), then both P610 and P611 must be entered to define the flow.
Two curve types are supported:
• P600 = 4–linear (piece wise linear)
• P600 = 5–curved (cubic spline)
Both are shown in the following chart.
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. 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 non linear
flow. A maximum of 32 breakpoints can be defined. The curve’s end point is always
specified by the parameters Maximum Head (P603) and Maximum Flow (P604) for a
maximum total of 33 breakpoints.
Use as many breakpoints as required by the complexity of your PMD.
See
Volume on page 50 for more information and parameters P610 and P611 for
characterization.
