Construction instructions for the standpipe
Radar sensors for measurement on surge or
bypass pipes are used in flange sizes DN␣ 50,
DN␣ 80, DN␣ 100 and DN␣ 150.
On the left is the construction of a measuring
pipe (surge or bypass pipe) in the example of
a sensor with a DN␣ 50 flange.
The radar sensor with a DN␣ 50 flange is only in
conjunction with a measuring pipe a functional
system.
The measuring pipe must be smooth inside
(average roughness Rz␣
≤
␣ 30). Use as measur-
ing pipe a stainless steel pipe without joint.
Extend the measuring pipe to the required
length with welding neck flanges or with con-
necting sleeves. Note that no shoulders are
caused in the pipe during welding. Fasten the
pipe and the flange before welding in aline-
ment with the inner sides.
Do not just weld through the pipe wall.
Roughnesses or joints must be smooth inside.
Roughnesses or joints must be removed care-
fully as otherwise strong false echoes and
build-up will be caused.
