2.15.4.8. OCM Dimension 4
See table under PMD Dimensions (2.15.4.) to relate OCM Dimension 1-4
above to a specific dimension for each directly supported Primary
Measuring Device. For PMDs that are not directly supported (
Universal
Head Flow
), use a Universal Flow calculation. See
Universal calculation
support
on page 116.
For more information on PMD, see
Open Channel Monitoring (OCM)
on
page 97.
2.15.5. Universal Head vs. Flow
In the following table, enter Head and Flow Breakpoints for universal
PMDs.
Head Breakpoints: The head breakpoints for which flowrate is known,
defined in Units (2.1.1.)
.
Flowrate Breakpoints: The flowrate corresponding to each Head
Breakpoint entered, defined in Flowrate Units (2.15.3.7.).
See
Universal calculation support
on page 116 for details on how to
specify universal flows.
Entering breakpoints via SIMATIC PDM:
