6. If an end support is to be mounted:
a. Take a cord and tie one of its ends around the welding socket. Wrap the other end of the
cord around the pipe so that it forms a loop around the pipe. Mark the half-way point of
the circumference on the pipe.
b. Drill a second hole with the diameter D1 into the pipe.
c. Tack-weld the end support onto the pipe by using the appropriate weld gap (typically
1/16" (1.5 mm)).
d. Insert the sensor into the pipe and check the alignment of the support. If necessary, adjust
the alignment.
7. Remove the sensor and finish welding the weld couplings as per the applicable piping codes.
8. For the model with an end support, weld the weld coupling and weld the cap into position.
9. Place the supplied gasket surface on the flange, insert the probe into the welding socket and
make sure that the arrow on the probe head points in the flow direction.
10. Tighten the bolts and nuts.
3.9.1
Installation of the shut-off valves (for the remote version):
The shut-off valves have to be mounted to the nozzles of the primary element before mounting the
sensor into the pipe.
3.9.2
Installation of the manifold and the transmitter (for the remote version):
The impulse pipes have to be installed with the required slope
(for liquids and steam:
→
ä
10, for gases:
→
ä
11).
• For steam and liquids, a venting possibility has to be provided at the highest point.
• For gases, a drainage has to be mounted at the lowest point. The impulse lines (+) and (-) have to
be mounted to the respective inlets (process connections) of the manifold.
The transmitter is directly screwed to the manifold with the supplied screws and gaskets.
