Requirements for Measuring Flow meter Accuracy
•
Medium must be conductive.
•
The pipe should be completely filled with the medium.
•
Medium conductivity should be homogeneous to avoid severe disruption. If chemical
substances need be injected into the pipe, the injection should be operated at upstream
side of flow meter.
•
Magnetic flow meter system should be connected to the ground.
•
There must be a straight pipe run no less than 5DN at flow meter upstream and 2DN at
flow meter downstream. (DN is the internal diameter of the pipeline).
•
Do not install the flow meter near large electrical machine or transformer in order to
avoid the electromagnetic interference.
NOTE
Do not expose the electronic unit box to direct sunlight; in case of outdoor
installation, use a suitable protection shield.
