• The stilling well must be smooth on the inside (average roughness R
z
≤ 6.3 μm (248 μin)). Use
extruded or parallel welded metal pipe. An extension of the pipe is possible with welded flanges or
pipe sleeves. Flange and pipe have to be properly aligned at the inside.
• Do not weld through the pipe wall. The inside of the stilling well must remain smooth. In case of
unintentional welding through the pipe, the weld seam and any unevenness on the inside need to
be carefully removed and smoothened. Otherwise, strong interference echoes will be generated
and material build-up will be promoted.
• In the case of smaller nominal widths flanges must be welded to the pipe such that they allow for a
correct orientation (marker aligned toward slots).
