Hauser 23
3.10 Installation steps for the welding flange 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. Loosely bolt the sensor, gasket and mounting flange together (hand-tight).
5. Insert the assembly until the tip of the sensor hits the opposite side of the pipe.
6. Align the head of the sensor so that the arrow labeled "flow" on the head is in the direction of
the flow to within 3°.
7. Tack-weld the mounting flange into position by using the appropriate weld gap (typically
1/16" (1.5 mm)).
!
Note!
The bolt holes of the flange must be at 45° angles (for four holes) or 22.5° angles (for eight
holes) to the pipe axis.

8. Remove the sensor and the sensor flange and finish welding the weld coupling to the pipe as
per the applicable piping codes.
9. For the model with an end support, weld the weld coupling and weld the cap into position.
Diameter of the hole D1

!
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?
