Torque on the pipeline
NOTICE:
If the FLOWSIC500 is installed so that the gas flow meter projects sideways
from the pipeline, the gas flow meter weight creates a torque on the pipeline.
▸ Make sure the pipeline is capable of holding the gas flow meter → p. 36,
Table 10.

Installation in pipeline
1 Select suitable bolts.
Recommended bolts → Table 7.
2 Use the hoisting equipment to position the FLOWSIC500 in the desired location in the
pipeline.
Lay the pipelines without tension to the device to be installed!
3 Insert and align the gaskets.
4 Apply anti-seize paste to the bolts.
5 First screw the bolts by hand into the adapter to the stop.
– Screw in the bolts according to DIN835 with the shorter thread end.
– The bolts according to ASME B18.31.2 can be screwed in with any end.
6 Check the thread length in the adapter is fully utilized.
7 Then install the washers and nuts, and tighten them by hand.
8 Check whether the thread length of the nut is fully utilized.
If necessary, use a different bolt length.
9 Check correct positioning of flange gaskets.
10 Tighten nuts evenly and crosswise in small steps until the specified tightening torque is
reached (→ Table 7).
Make sure the flange sits free of tension.
11 Slowly increase the pressure in the pipeline.
Gradient: Max. 3bar/min (45psi/min)
12 Carry out a leak tightness check on the pipeline (in accordance with the pipeline manufacturer's specifications).
