: Outlines the relationship between inter-laboratory transfer standards and working standards used in field testing. Core Sections of the Code Content Focus Section 1 Object and Scope Section 2 Definitions, Terms, and Units Section 3 Detailed Measurement Devices & Ranges Section 4 Calibration Procedures and Standards Section 5 Measurement Installations & Probes Section 6 Uncertainties in Pressure Measurement
The code provides a structured approach for determining the uncertainty of pressure measurements. This is critical because performance test results are only meaningful when accompanied by their uncertainty——a fundamental concept reinforced by ASME PTC 19.1 on Test Uncertainty.
Procedures for verifying instrument accuracy before and after testing. C. Dynamic and Special Measurements asme ptc 192
Proper placement of pressure taps, impulse lines, and probes directly affects measurement accuracy. The code specifies requirements for:
Follow code guidance for:
: Procedures for ensuring instruments are traceable to national standards.
You might be thinking, “We use HART, Foundation Fieldbus, and wireless transmitters. The tubing is gone!” The code specifies requirements for: Follow code guidance
Modernized standardizing principles by refining electronic transmitter protocols, handling rapid dynamic responses, and incorporating rigorous mathematical uncertainty modules.
The significance of this code lies in its role as the "referee" method. When performance guarantees are contractually bound, PTC 19.2 provides the mutually accepted standard for determining whether pressure readings are valid and accurate. “We use HART
