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 bolt the sensor, gasket and mounting flange together (hand-tight).
4. Insert the assembly into the pipe. 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°.
5. 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.
