6.6 Calibration for simultaneous level and flow
measurement with one sensor
It is possible to measure level and flow
simultaneously with one sensor. This is
especially useful for stormwater overflow basins.
For this type of measurement the sensor must be
mounted above the basin and the appropriate
distance to the weir crest must be observed (for
details refer to the description of weirs in the
appendix).
The measured values can be communicated by
the current outputs or the HART signal.
Calibration
1. Go to the "device properties/operating
param./operating mode" parameter and
select the option "level+flow".
2. Go to the "level" menu and calibrate the
level measurement as described in the
Operating Instructions BA 288F, Chapter
6.4.
3. Go to the "flow" menu and calibrate the
flow measurement as described in chapter
6.4 of this manual. Select the same sensor
as for the level measurement.
Note!
It is recommended to perform the interference echo suppression when calibrating the level
measurement. This suppression is automatically valid for the flow measurement as well. Therefore,
the interference echo suppression can be skipped when calibrating the flow measurement.
