MOUNTING 6
6.3 Fitting in the pipeline
The measuring device can be installed horizontally or vertically.
Installation location
Fit the device in an easily accessible and protected position. Carry out all assembly work
on-site. The following must be taken into account:
▸ Maintain the ambient temperature range in accordance with the technical data under
consideration of possible radiant heat (shield when necessary).
▸ Protect the device against direct sunlight and atmospheric conditions.
▸ Select an installation location free from vibrations when possible and stabilize vibrations
when necessary.
▸ Provide sufficient clearance for cables and opening the front panel.
▸ Select an installation location free of chemical influence
Installation in pipeline
1 Select suitable bolts.
2 Position the measuring device in the desired location in the pipeline. Lay the pipelines
without tension to the device to be installed!
3 Insert and align the gaskets. The gaskets must not project into the area through which
the gas flows and must be centered on the sealing surface.
4 Apply lubricant to the bolts.
5 First screw the bolts by hand into the meter body to the stop.
6 Check the thread length in the meter body 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. The gaskets must not project into the area
through which the gas flows and must be centered on the sealing surface.
10 Tighten nuts evenly and crosswise in small steps until the specified tightening torque is
reached. Make sure the flange sits free of tension.
11 Slowly increase the pressure in the pipeline.
Gradient: Max. 1 MPa/min (10 bar/min)
12 Carry out a leak tightness check on the pipeline (in accordance with the pipeline operat-
ing company's specifications).
NOTICE: Observe the gas flow direction
Install the device so that the flow conditioner is at the gas inlet.
