Installing The Transmitter During Actual Operation - ABB Sensyflow FMT500-IG Inbetriebnahmeanleitung

Weld the hot tap fitting in the pipeline while taking account of the following points:
- Observe thickness of pipeline wall and degree of shrinkage when welding.
- The distance h from the upper edge of the fitting flange to the the pipe central axis must be
within a tolerance of ± 2 mm (0.08 inch) when in the measuring position.
- It is essential to maintain a right angle to the pipe axis (max. tolerance: 2°).
- The adapter centering pin must be aligned with the pipe axis in the flow direction (outflow
side, behind the measuring point), see Fig. 12.
NOTICE - Potential damage to parts!
If the welded joints become hot, warping of the sealing surfaces and / or damage to the O-
rings can occur.
Pause occasionally to allow the fitting to cool.
IMPORTANT (NOTE)
Deviations from the stated dimension and position tolerances cause additional measuring
uncertainty.

Installing the transmitter during actual operation

- The hot tap fitting must be in the disassembly position (Fig. 11), whereby the Sensyflow
opening is sealed.
- Insert the O-ring (55 x 3 mm [2.16 x 0.12 inches]) into the groove provided for this purpose
(Fig. 13). The O-ring gasket and screws are included in the scope of delivery.
- Insert the transmitter in the hot tap fitting and secure with screws (two M12 screws and two
extended special screws, installed opposite each other (Fig. 14)).
- Install the dust caps and use nuts to attach them to the special screws (Fig. 14).
- Rotate the transmitter into the measuring position using the lock nut (Fig. 14). The lower
edge of the lock nut indicates the position of the measuring element. When you reach the
measuring position 50 – OPEN – MESSEN (lower limit stop of lock nut), the measuring
elements are in the middle of the pipeline and it is only at this point that accurate values can
be provided (see detail A in Fig. 9).
NOTICE - Potential damage to parts!
Using tools or other devices to operate the lock nut can damage the hot tap fitting.
Only ever operate the lock nut manually.
- Transmitter electrical connection (see Section 5).
