Review: ASME PTC 19.2 – Pressure Measurement (Part of the Performance Test Codes)

The Official Source: ASME Digital Collection

The only verified repository is the ASME eLibrary or ASME.org.

• Cost: Expect to pay between $100 to $300 USD for the current edition.
• Format: ASME provides a DRM-protected PDF or a standard PDF with watermarking.
• Subscription: Many universities and major EPCs (Engineering, Procurement, and Construction firms) have site licenses. Check your corporate library first.

3. Test Conduct

You cannot simply run the turbine at any load. The code specifies:

• Steady-state conditions: Temperatures and pressures must be stable for a defined period (usually 10 to 30 minutes).
• Fuel analysis: Gas chromatograph data for LHV (Lower Heating Value) is mandatory.
• Shaft alignment: Parasitic losses from gearboxes and generators must be accounted for.

A. Terminology and Definitions

The standard rigorously defines pressure types to avoid ambiguity: asme ptc 192 pdf

• Gauge Pressure: Pressure relative to ambient atmospheric pressure.
• Absolute Pressure: Pressure relative to a perfect vacuum.
• Differential Pressure: The difference between two applied pressures.
• Static vs. Total Pressure: Distinguishing between the pressure exerted by a fluid at rest (static) and the pressure including the kinetic energy of the fluid flow (total).

C. Measurement Uncertainty

A significant portion of the document is dedicated to uncertainty analysis. It guides engineers on how to combine elemental errors (calibration errors, data acquisition errors, installation errors) to determine a total measurement uncertainty. This is vital for passing a performance test, as test results are only valid if the uncertainty falls within the code's allowable limits.
