Installing the sensor
Opening and closing the terminal box
Note
For achieve the best results, ensure the gaskets fit
concentrically with the meter tube
To ensure that the flow profile is not distorted, the gaskets
must not protrude into the piping.
To open the housing, release the cover safety device by
screwing in the screw
1
.
After closing the housing, lock the housing cover by
unscrewing the screw

.
Note
Potential damage to device.
• The use of graphite with the flange or process connection
gaskets is prohibited. This is because, in some instances,
an electrically conductive coating may form on the inside
of the meter tube.
•
Vacuum shocks in the piping should be avoided to
prevent damage to the liners. Vacuum shocks can destroy
the device.
Note
Impairment of the IP rating
• Make sure that the cover of the power supply terminals is
mounted correctly.
• Check the O-ring gasket for damage and replace it if
necessary before closing the housing cover.
• Check that the O-ring gasket is properly seated when
closing the housing cover.
The flowmeter sensor can be installed at any location in the
piping while taking the installation conditions into account.
1
Remove protective plates, if present, to the right and left
of the meter tube. To prevent possible leakage, make
sure that the liner on the flange is not cut or damaged.
2
Position the flowmeter sensor coplanar and centered
between the piping.
3
Use the appropriate screws for the holes in accordance
with chapter "Torque information" on page 81.
4
Slightly grease the threaded nuts.
5
Tighten the nuts in a crosswise manner as shown in the
figure. Observe the tightening torques in accordance
with chapter "Torque information" on page 81. First
tighten the nuts to approx. 50% of the maximum torque,
then to 80 %, and finally a third time to the maximum
torque. Do not exceed the maximum torque.

Risk of injury due to live parts .
When the housing is open, contact protection is not
provided and EMC protection is limited.
Before opening the housing, switch off the power supply.
