Note!
• Do the pipe dimensions (inner diameter, wall 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?
1.
Completely depressurize and drain the pipe prior to installing the Deltatop.
2.
Drill a hole with the diameter D1 into the pipe.
3.
Loosely assemble the sensor to the welding socket (hand-tight) and insert the sensor assembly
into the pipe.
4.
Tack the welding socket into position by using the appropriate weld gap (typically 1/16"
(1.5 mm)).
5.
Remove the sensor.
6.
Protect the threads on the welding socket and finish welding the welding socket to the pipe as
per the applicable piping codes.
7.
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 probe into the pipe and check the alignment of the support. If necessary, adjust
the alignment.
