For steam sampling, the standard mandates —meaning the velocity of steam entering the probe must equal the velocity of the steam in the main pipe. If the probe velocity is too high or low, the sample will either over-represent or under-represent water droplets and solid particulates. Asme Ptc 19.11 Pdf

For accurate online chemistry monitoring, the standard specifies that the "delay time" from the sample tap to the analyzer should be minimized—typically under 60 seconds for fast-loop systems—to avoid degradation of unstable analytes (like dissolved oxygen or ammonia).

Specifically, this code serves as a guide for the measurement of physical properties of process fluids, focusing heavily on:

One of the most cited sections in the deals with the calculation of fluid density. In high-pressure gas lines, gases do not behave ideally. The Ideal Gas Law ($PV=nRT$) fails under the extreme pressures found in power plants and pipelines. PTC 19.11 outlines the equations of state and compressibility factors required to correct these measurements.
