4.1 Installation instructions
CAUTION! Risk of malfunction due to external mag-
netic fields!
Magnetic fields close to the device can cause malfunctions and
should be avoided.

Ensure that no external magnetic fields are present at the
instal-lation site of the IVMZ .2.
• The IVMZ .2 can always be installed anywhere along the
pipeline. However, straight sections of piping are preferable.
•
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 necessary.
To reach a most highly accuracy of the measurement, you should use straight inlet and
outlet sections according to the nominal width (DN). The inlet 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.
• If two or more IVMZ .2 devices are used side by side, maintain
a separation of at least 2.5 cm between adjacent devices.
If adjacent devices are too close together, operation of both
devices may be impaired due to mutual interference.
