Open Channel Monitoring P600 to P621 MR | Siemens 200 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: See Open Channel Monitoring (OCM) on page 73 for application examples 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 P801 Range Extension on page 200 for more information.
