Installation of the ITABAR Sensor

In difference to other suppliers the ITABAR-Flow-
Sensor everytime will be build in in the horizontal
line of the pipe and always have condensate pots.
Therefore the influence of condensation and
vaporization is minimized. Please pay attention that
both condensate levels on plus and minus pressure
pipe will be the same. This means both pots must be
on the same horizontal line and there has to be no air
in the pulse tubes and the chambers of the
transmitter.
Following problems will happened by using sensors
of other manufactors who does not use condensate
pots or prefered installation of the sensor on the
lower side of the pipe:
•
Condensation and vaporization happened in the
sensor profil. For this reason there is a great
influence to the level of the condensate column.
•
There is no energy balance between plus and
minus process connection.
•
no equal temperatures in the condensate
columns.
•
No chance to correct misalignments
It is not allowed to install ITABAR-Flow-Sensor at
the top of the pipe. If costumer did so, he is not able
to get out all air from the sensor and the condensate
pots. The energy of the system will not be
transmitted without loss to the transmitter. The
kinetic energy will be changed particulary changed
to potential energy. This is eliminated for ITABAR-
Flow-Sensors.
Observe the general installation instructions!
It is particularly important to make sure that the
distance from the gasket surface to the pipe agrees
with the H-dimension you gave in your order (see
Fig. 8).
ITABAR sensors of the type IBFD are supplied with
the following standard H-dimensions:

IBFD-25/26

Installation of Type IBFD-20
1. Drill a hole of 18 mm diameter into the pipe.
2. Tack the mounting flange onto the pipe leaving a
clearance of 1-2 mm. The bolt holes of the flange
must be at 45° angles to the pipe axis (see Fig.
9).
Check the alignment of the mounting flange.
Fig. 8
3. Observe the H-dimension during the welding of
the mounting flange (see also Fig. 8).
4. Check the alignment of the mounting flange
again - this is importatnt for the exact position of
the condensation vessels.
5. Now the ITABAR sensor can be installed into
the pipe. Place the included gasket on the gasket
surface of the flange. Insert the sensor into the
welded stud and make sure that the arrow on the
sensor flange points in the flow direction.
Tighten the bolts and nuts.
6. Now check the alignment of the condensation
vessel. The condensation vessel have to be
perfectly mounted along a horizontal line.
Check the alignment!
For correction of alignment slightly release stud
bolts on the mounting flange. For correct align-
ment tighten stud bolts with required torque
according table 1.
