Process tap location
taking a wider view
the process tap is where the process fluid meets the sampling system that
the tap is the source of the analyzed sample . so you have to get right. A tap in process line
is a very simple thing. It’s just s hole in the pipe . But that simplicity conceals a large number of
choices made more or less consciously during its design and fabrication . there is a lot to think
about, so that’s why there is so much detail in this chapter.
Getting the tap right is almost as important to laboratory grab sampling as it is automic
On-line analyzer. The laboratory will not so much care about getting a fast sampling. But they
Certainly need to pull a representative one. So this chapter may be as helpful to the plant
Chemist as is to the analyzer specialist .
