e. Remove the probe and perform the finish welding.
8. Using appropriate pipe thread sealant, install the compression body into the welding socket.
9. The tapered end of the front ferrule must point towards the compression body.
10. The back ferrule must be next to the front ferrule with the tapered end pointing toward the
front ferrule.
11. Insert the probe, with the union compression nut and ferrules attached, into the compression
body (do not tighten) until the sensor tip touches the opposite pipe wall or the end support.
12. Align the head of the sensor so that the cover labeled "flow" on the head is in the direction of
the flow in the pipe to within 3°.
13. While pushing the sensor against the opposite wall with a force of at least 50 lbs (22 kg) tighten
the union compression nut.
14. Check the sensor alignment again. If the sensor is not aligned correctly, loosen the union
compression nut and repeat the last installation step.
3.7.1 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.

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:

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.
