Open Channel Monitoring (P600 to P621)
If the HydroRanger 200 is used to monitor open channel flow, alter the following
parameters as required and run a calibration as described in P621.
The HydroRanger 200 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 188 for more information.
