3.8 Installation steps for the welding socket version with a
spring lock
1. Completely depressurize and drain the pipe prior to installing the Deltatop.
2. Drill a hole with the diameter D1 into the pipe.
3. With the follower and packing rings already in place, loosely insert the sensor into the spring
lock body.
4. Thread the spring lock body into the welding socket (hand-tight) and then insert the complete
assembly into the pipe.
This ensures the welding socket is properly aligned to the hole already drilled in the pipe.
5. Tack-weld the welding socket into position by using the appropriate weld gap (typically 1/16"
(1.5 mm)).
6. Remove the sensor and spring lock body.
7. Protect the threads on the welding socket and finish welding the welding socket to the pipe as
per the applicable piping codes.
8. Using appropriate pipe thread sealant, thread the spring lock body into the welding socket.
9. With the follower and packing rings already in place, insert the sensor into the spring lock body
until the tip of the sensor hits the opposite side of the pipe.
!
Note!
The three studs must pass through the indicator ring and the load plate.
10. Align the head of the sensor so that the arrow labeled "flow" on the head is in the direction of
the flow in the pipe to within 3°.
11. Maintain the head in this position for the remainder of the installation procedure.
12. Place the three lock washers and the three load nuts on the studs and tighten.

thickness, thickness of insulation) match the
data of the order and the specifications of the
device?
• Do the medium properties and process data
match the specifications on the supplied
calculation sheet?
