Flow Sensor SS 20.600
Page 18
Remove the protective cap from the sensor head; carefully insert the
sensor into the guide of the compression fitting so that the center of the
chamber head is placed at the measuring position in the middle of the
pipe.
Adjust the sensor manually at the sensor enclosure by turning it coun-
terclockwise by approx. 80° (observe the flow arrow on the housing
cover). Make sure that the immersion depth is maintained.
Tighten the spigot nut slightly by means of a key wrench (AF24) to fas-
ten the sensor.
Use a fork wrench (AF27) to lock the hexagon bolt at the screw pipe
connection. Use another key wrench (AF24) to tighten the spigot nut of
the compression fitting until the arrow on the sensor housing complies
with the direction of the pipe flow.
Check the set angular position carefully, for example by placing a bub-
ble level on the aligning surface of the sensor enclosure.
The angular deviation should not be more than
3° with respect
to the ideal measuring direction. Otherwise, the measurement
accuracy may be affected.
In case of wrong adjustment, the compression fitting has to be loosened
and the alignment procedure must be repeated.
Shorten the safety chain by removing the superfluous chain links so that
the chain is slightly tensioned after being locked at the housing. Finally,
secure the chain with a padlock.
General note:
Do not use the alignment surface of the housing for mechanical
adjustment, e.g. for locking.
There is risk of damage to the sensor.
Mounting of remote version
The sensor probe of the remote version is mounted with a compression
fitting in the same way as the compact sensor.
A wall mounting bracket is provided for fastening the sensor housing.
