Review: ASME PTC 19.2 – Pressure Measurement (Part of the Performance Test Codes)
6. Conclusion
ASME PTC 19.2 remains the foundational standard for pressure measurement in performance testing. It bridges the gap between theoretical fluid mechanics and practical instrumentation engineering. For any engineer involved in the testing of high-value rotating equipment or thermal systems, mastery of PTC 19.2 is essential for ensuring data integrity and contractual compliance.
The American Society of Mechanical Engineers (ASME) provides several Performance Test Codes (PTCs) to standardize how industrial equipment is tested. One critical supplement in this series is ASME PTC 19.2, which focuses on the accurate determination of pressure values. Understanding ASME PTC 19.2
ASME PTC 19.2, titled "Pressure Measurement," serves as a specialized guide for measuring pressure during the performance testing of various power plant and mechanical systems.

What is ASME PTC 19.2?
Full Title: ASME PTC 19.2 – Pressure Measurement Current Issue: ASME PTC 19.2-2010 (Supersedes the 1987 edition).
Overview: This standard is part of the Performance Test Codes (PTC) series published by the American Society of Mechanical Engineers (ASME). While most PTCs focus on testing specific machinery (like turbines or compressors), PTC 19.2 is a "supplementary" standard. It provides the fundamental guidelines on how to accurately measure pressure during any performance test.
B. Instrumentation Types
PTC 19.2 categorizes pressure gauges and transducers based on their principle of operation:
- Liquid Column Manometers: (e.g., U-tube, inclined manometers) used for high-accuracy, low-pressure differential measurements. The standard outlines corrections for temperature, gravity, and fluid density.
- Elastic Element Gauges: (e.g., Bourdon tubes, bellows, diaphragms). The standard details hysteresis, drift, and repeatability errors associated with mechanical gauges.
- Transducers: Electronic devices converting pressure into electrical signals. The standard emphasizes the need for thermal compensation and signal conditioning.
Why is this Standard Important?
In engineering, small errors in pressure measurement lead to large errors in efficiency calculations.
For example, if you are testing a steam turbine, the power output is calculated based on the pressure drop across the stages. If your pressure sensors are not installed correctly or calibrated according to PTC 19.2, your efficiency calculation could be off by several percentage points—potentially costing a power plant millions of dollars in lost revenue or contractual penalties.

2. Instrumentation and Uncertainty Analysis
This is the most crucial chapter. The code dictates:
- Temperature probes: Required number of thermocouples per plane (intake and exhaust).
- Flow measurement: ASME nozzles, venturis, or pitot traverses.
- Uncertainty: The code mandates that the total random uncertainty of the power measurement must be calculated. Most standard tests target ±1.0% uncertainty for power.
