Heavy particulate matter bypasses the probe due to momentum, resulting in an under-reported contaminant level.
: Guidelines for both online monitoring and grab-sample analysis to ensure data quality and uncertainty management. Critical Technical Requirements Asme Ptc 19.11 Pdf
Reducing the temperature and pressure of the sample to safe, measurable levels without altering its chemical makeup. Heavy particulate matter bypasses the probe due to
Water and steam samples do not naturally stay mixed at high temperatures and pressures. Without the precise mechanics mandated by PTC 19.11, phase separation occurs. Operators end up analyzing "clean" water while heavy contaminants cling to the pipe walls, completely missed by the sensors. Core Components of an ASME PTC 19.11 Sampling System Water and steam samples do not naturally stay

Whether you are testing a 1,200 MW nuclear fleet or a 50 MW biomass boiler, PTC 19.11 protects you from bad data. A $150 investment in the legal PDF saves a $500,000 mistake from invalid test results.
