Open Channel Monitoring (Ocm) [Mr 200]; Common Parameters - Siemens MAG 1100 Operating Instructions Manual

Open Channel Monitoring (OCM)
[MR 200]
An OCM installation is defined one of three ways, based on the Primary Measuring
Device (PMD):
1. Dimensional (P600 = 2,3,6,7)
For some common weir and flume types. PMD dimensions (P602) are entered directly.
• BS-3680 / ISO 1438/1 Thin plate V notch weir on page 74
• BS-3680 / ISO 4359 Rectangular Flume on page 75
• Palmer Bowlus Flume on page 76
• H Flume on page 77
2. Exponential (P600 = 1)
For most other weir and flume types. PMD exponents provided by the manufacturer are
entered. Flow is calculated using the exponent (P601) and the maximum values (P603 and
P604).
• Standard Weirs on page 78
• Parshall Flume on page 79
• Leoplod Lagco on page 80
• Cut Throat Flume on page 81
3. Universal (P600 = 4,5)
For all other PMDs, the head-to-flow curve can be plotted based on known breakpoints,
usually supplied by the PMD manufacturer.
