ITABAR Flow Sensor Type
IBF
Operating
Manual
8. Measurement
Start-Up
Make sure that:
- all installation openings are closed
(sensor end support IBF-21 / 26 / 36 / 66).
- all installed parts are securely bolted together.
- all instrument valves are closed.
Now the pipe can be cleared for the appropriate
medium
Check all connections, especially the flanges
Then open the instrument valves to the
∆
p-transmitter.
9. Preventive Maintenance of the ITABAR-
Sensors
ITABAR sensors are insensitive to dirt and soil
build-up and therefore nearly maintenance-free.
10. Trouble
shooting
If, after the start-up of the ITABAR sensor, any
measuring errors occur, they may possibly be
corrected quite easily:
error:
No differential pressure indication.
Correction:
Check whether all instrument valves to the
∆
p
transmitter are opened.
Check the alignment of the sensor with the pipe. The
arrow on the sensor must point exactly in the flow
direction (downstream).
Note:
With highly corrosive media it is possible (if the
sensor material has been specifically selected for
such operating conditions) that a connection
between the plus and minus sides has been formed.
This can only be checked after removal of the sensor
from the pipe. Close the holes in the sensor rod and
blow through both minus and plus connections of
the sensor (e.G. with pressurized air). If air emerges
from the opposite connection, the sensor is
defective. In this case, please notify the
manufacturer.
