5.1.3 Probe alignment
During mechanical assembly of the FSD-3, make sure
that the installation mark points in the opposite direction
of the flow direction of the medium.
5.1.4 Sealing
For sealing the process connections with parallel
threads, use flat gaskets, lens-type sealing rings or WIKA
profile sealings at the sealing face. With a tapered thread
(e.g. NPT thread), sealing is made in the thread using
additional sealing materials, e.g. PTFE tape (EN 837-2).
For further information on seals see WIKA
data sheet AC 09.08 or at www.wika.com.
5.1.5 Disturbing interferences in the piping system
For correct measurement, the flow switch requires a fully
characterised flow profile. This is why calming sections
must be provided in the pipeline after a pump, a pipe
elbow, installed parts and changes in cross-section.
