Compac stainless steel sealing cone
3.2
The Compac sealing cone makes up the intersection between the
measuring station and sensor. Please note the following design details for
correct positioning of the components after welding in the pipeline
according to the direction of flow: The straight pin of the measuring station
engages in the one-sided bore of the Compac sealing cone.
This is designed with a slot that receives the sensor pin in the downstream
direction of flow.
Compac welding neck flange (V flange) steel
3.3
The connection between the measuring point interface and the pipe
system is made by the Compac welding neck flanges. These seal twice –
both metal-wise and against an O-ring made of Viton in a circumferential
groove in the measuring station. The advantages of these flanges in
comparison to standard DIN flanges with flat seals are the significantly
smaller construction volume and thus material volume and weight, lower
bolt tightening forces and the prevention of overstraining of the seal (with
regard to deformation and compression) – with higher density efficiency
and leakage reliability. Slight scratches in the contact surfaces are
tolerated without loss of function due to the high compressive force.

Note
An alternative to the welding neck flange (V flange) is to fit a Compac threaded
flange (G flange).

To avoid a mixed seam in the welded joint to the pipeline,
make sure that the Compac flanges are made of steel or
stainless steel according to the pipeline.
