If you see “PTC 192” on an old drawing, it is almost certainly a transcription error of . And when paired with “Fixed,” they mean a permanent, code-compliant pressure tap installation.
: The code covers various types of pressure-sensing devices, including: Manometers and liquid columns. Deadweight testers. Elastic gauges (Bourdon tubes). Electronic pressure transducers. asme ptc 192 fixed
In the field of thermodynamic testing, pressure is a secondary measurement—its value is used to derive primary performance metrics such as power output, heat rate, efficiency, and flow rate (via ASME PTC 6 or 19.5). Consequently, small errors in pressure measurement propagate into significant uncertainties in final results. If you see “PTC 192” on an old
