Liquid Applications – Standpipes
In many applications, access must be made using a standpipe. Siemens Milltronics can
provide factory bonded flanged transducers or a split flange kit that will readily mate to
the flanged standpipe. Another option is to hang the transducer from a blind flange.
The standpipe's length should be as short as possible and its diameter as large as
possible. Generally, the –3 dB cone of the sound beam should not intersect the standpipe
wall in the application's opening into a vessel or a larger area. Otherwise, additional
blanking will be required to compensate for the interference zone created by the opening.
Note:
When using a stilling well, make sure there is no build-up, welds, couplings, or
other debris on the inside of the well wall. This can affect the reliability of level
