Siemens 200 instruction manual Flow Calculation, Universal, Curved MR, Set P050 =

Universal, Curved [MR 200]

Please note that the Universal, Curved feature is only available on the MultiRanger 200.

Set P050 = 10

This calculation creates a cubic spline approximation of the level/volume curve, providing best results if the curve is non-linear, and there are no sharp angles.

Appendix B: Tech Reference

Select at least enough breakpoints from the curve to satisfy the following:

•two breakpoints very near the minimum level

•one breakpoint at the tangent points of each arc

•one breakpoint at each arc apex

•two breakpoints very near the maximum level

For combination curves, enter at least two breakpoints immediately before and after any sharp angle (as well as one breakpoint exactly at the angle) on the curve.

Flow Calculation

Please note that the Flow Calculation feature is only available on the MultiRanger 200. The MultiRanger provides numerous OCM flow calculation features (P600 to P611).

If the PMD (primary measuring device) does not match any of the eight preset PMD calculations, or if a PMD is not used, select a Universal Volume calculation. Use the head/ flow graph or chart provided by the PMD fabricator (or create one based on the PMD or channel dimensions).

Based on the graph, choose the Universal Flow calculation, and select the head versus flow breakpoints to be entered (32 max). Generally, the more breakpoints entered, the greater the flow calculation accuracy.
