Analyser (with sample probe)

ISA 5.1-2009/2022 (primary element symbols) / PIP PIC001

Drawn as

An AT (or AE) bubble linked to a probe that dips into the line, with the measured component written beside the bubble (O2, H2S, H2O, OIW, BS&W, CO2…).

Meaning

Online analyser: water dew point, H2S, oxygen, oil-in-water, BS&W or water-cut. In-line probes sit on the pipe; extractive analysers have a sample line to an analyser shelter (analyser-shelter). No single component for the probe.

Variants

The analyte is written beside the bubble, not as part of the tag
Extractive systems show a sample line, conditioning box and return
Gas chromatographs on metering skids are AT with "GC"
