3.13.1
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.
3.13.2
Installation of the manifold and the transmitter (for the remote version):
The impulse pipes have to be installed with the required slope
(for liquids or steam:
10; for gases:
• 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.
3.13.3
Sensor insertion of the probe without process interruption
#
Warning!
The flow rate must be decreased to the amount stated on the Deltatop tag: the maximum insertion/
withdrawn dp / flow limit.
1.
Verify that the threaded rod is adequately greased prior to inserting the sensor.
!
Note!
A high-temperature grease should be used for all steam applications and for temperatures
above 200°F (100°C).
2.
Completely open the access valve.
3.
Then, using the drive nut, insert the sensor.
4.
The tip of the sensor should completely bottom on the sensor until firm resistance is met. This
will occur when the sensor plate is approximately 2" (51 mm) from the top of the packing
gland.
5.
Thread the jam nut towards the threaded bushing. The jam nut should press tightly against the
threaded bushing. This will lock the drive rod in place and maintain the sensor position in the
pipe.
3.13.4
Sensor removal of the probe without process interruption
#
Warning!
The flow rate must be decreased to the amount stated on the Deltatop tag: the maximum insertion/
withdrawn dp / flow limit.
1.
Shut off device valves (disconnect the impulse pipe if necessary).
2.
Loosen the jam nut. Using the drive nut, retract the sensor until the stop nut and jam nut are
pressing against the threaded bushing.
3.
Completely shut off the access valve.
4.
Slowly open one of the Deltatop device valves and bleed off any remaining pressure contained
in the access nipple.
5.
The sensor assembly can now be removed.
