Installing the flowmeter sensor and pipe components
Pipe components can be supplied in a wafer type design (type 1) or as a measuring section
(type 2) (see Fig. 5) and should be installed stress-free (without torsion / bending stress) in the
pipeline along with the appropriate gaskets.
Gaskets must not alter the cross-section of the opening in the pipeline and must ensure
complete tightness once the flowmeter sensor and pipe component have been installed. It must
be ensured that the gaskets are compatible with the measured medium and the associated
temperature.
In the case of the type 1 pipe component (wafer type design), care must be taken to ensure
centered installation. The internal diameters of the pipe and flange must match exactly. Any
differences in levels or edges, or untidy weld seams, will reduce the measuring accuracy.
Installation is described using the example of a pipe component of type 1 with the wafer type
design. The description also applies to a type 2 pipe component and the weld-on adapters.
The flow direction must correspond to the arrow indicated on the pipe component. The
centering pin on the pipe component / weld-on adapter must be located on the outflow side
(behind the measuring point).
