WARNING!
Danger due to leaking system
Leaks in the system may occur when the flow sensor is
installed within a piping system. These leaks can lead
to a variety of different dangers.
The following must be observed when installing the
flow sensor:
–
The inner diameter of the seals is always equal to
or greater than the inner diameter at the connection
of the pipeline.
–
Seals must always be checked for damage and
cleanliness.
–
Seals must always be properly installed.
CAUTION!
Short circuit of the measuring signal due to incor-
rect sealing compound
If impermissible sealing compounds are used, an elec-
trically conductive layer can form on the inside of the
measuring tube of the sensor. As a result, short circuits
of the measuring signal are possible.
–
Never use electrically conductive sealing com-
pounds such as graphite.
5.
Install the flow sensor in the intended position.
Pay attention to the following:
n
Only approved installation tools may be used for the
flanges and process connections.
n
All transition pieces, fittings and the like must be firmly
connected and sealed.
n
Only suitable and approved lubricating pastes or sealing
compounds may be used.
n
The flow sensor must be installed in the correct flow
direction.
n
The sensor must be firmly and securely installed in the
pipeline with seals.
n
All torques must be observed during assembly.
6.
Check the piping system for leaks in the area of the flow
sensor.
7.
Connect the flow sensor electrically.
