Installation instructions

CAUTION!
Risk of malfunction due to external magnetic fields!
Magnetic fields close to the device can cause malfunctions and
should be avoided.
Ensure that no external magnetic fields are present at the
installation site of the FMG90.
•
The FMG90 can always be installed anywhere along the pipeline. Straight sections of
piping are preferable, however.
•
Installation can occur in horizontal and vertical pipes. The flow sensor is only suitable for
application in completely filled pipe systems.
•
As a matter of principle magnetic inductive flow sensors are widely independent from the
flow profile. An inlet section is not absolutely necessary.
To reach a most highly accuracy of the measurement, you should use straight inlet and
outlet sections according to the nominal pipe diameter (DN). The inlet pipe section has to
be at least 10 x DN; the outlet section 5 x DN in order to achieve the specified accuracy.
•
The inlet and outlet sections and the gaskets must have the same or a slightly larger
inside diameter than the measuring tube in order to achieve the specified accuracy.
