Implement an engine that analyzes the collected data against the performance metrics and tolerances defined in ASME PTC 19.2, ensuring that the feedwater heaters are operating within the specified standards. Where: Ensuring the hole is perpendicular to the
For an audit or performance test report, your documentation must include: It is called "Fixed" because the pressure is
The as defined by ASME PTC 19.2 is the use of a deadweight tester (also known as a deadweight gauge or piston gauge) as the calibration standard. It is called "Fixed" because the pressure is generated by fixing known weights onto a piston of a known effective area, which floats freely in a cylinder. The pressure (P) is calculated via the fundamental equation:
