Construction instructions for 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 func-
tional system.
The measuring pipe must be smooth inside
(average roughness Rz!
≤!30). Use as mea-
suring pipe a stainless steel pipe without
joint. Extend the measuring pipe to the re-
quired length with welding neck flanges or
with connecting sleeves. Note that no shoul-
ders are caused in the pipe during welding.
Fasten the pipe and the flange before weld-
ing in alinement with the inner sides.
Do not just weld through the pipe wall.
Roughnesses or joints must be removed
carefully as otherwise strong false echoes
and build-up will be caused.
