: Bourdon tubes, diaphragms, and bellows.
Unchanging errors inherent to the instrument design, installation geometries, or calibration limits.
Establishes standards for performance testing of pressure measurement instruments to ensure accuracy and reliability. Key Topics: Definitions of pressure measurement terms.
ASME PTC 19.2 is a standard published by ASME that provides guidelines for the performance testing of instruments and measuring systems used in power and process applications. The document outlines the procedures and requirements for testing and evaluating the performance of various instruments and measuring systems, including temperature, pressure, flow, and level measurement devices.

For anyone involved in performance testing, calibration, or instrument installation, the is an indispensable resource. By adhering to the standards outlined, engineers can ensure that pressure measurements are accurate, reliable, and legally sound.
I can, however, help with any of the following (pick one):
While main PTC codes (like PTC 4 for boilers or PTC 10 for compressors) dictate what to test, PTC 19.2 dictates how to measure the specific variable of pressure. It is widely regarded as the industry bible for precision pressure measurement in industrial, aerospace, and power generation applications.
The authorized and most up-to-date version of the standard is available for digital purchase or hardcopy delivery directly through the ASME Store .
To get a better sense of how to use this standard, you might want to consider:
Sloping lines are required to ensure liquids drain out of gas lines, and gas bubbles escape from liquid lines.
In real-world industrial environments, pressure readings often fluctuate (pulsate) due to pumps, compressors, or combustion instabilities. PTC 19.2 provides methodologies for:
: Many engineering firms and academic institutions maintain enterprise subscriptions giving employees and students free access to the entire ASME library.
While ASME sells hard copies, the industry demands the format for three critical reasons:
