Open Channel Monitoring (P600 To P621) [Mr 200] - Siemens MAG 1100 Operating Instructions Manual

Open Channel Monitoring (P600 to P621) [MR 200]

Open Channel Monitoring (OCM) operation is a MultiRanger 200 feature only.
If the MultiRanger is used to monitor open channel flow, alter the following parameters
as required and run a calibration as described in P621.

Note:
involving common weirs and flumes.
The MultiRanger measures head as referenced to Empty (P006) or OCM Zero Offset
(P605), when Operation is set for OCM (P001 = 6). Flowrate, based on head (at the point of
measure specified by the Primary Measuring Device fabricator) is also calculated and
displayed on the LCD.
Some Primary Measuring Devices require a longer Range Extension (P801) to avoid
entering the LOE failure state if the water level falls below the zero point of the Primary
Measuring Device. See
