ABSTRACT:
A method and apparatus are set forth for calibration of a flowmeter in a system having a condensible fluid flowing in it. A known volume of a liquid test solution is inserted into the system flowpath upstream of the flowmeter with the solution having dissolved in it a known concentration of an inert gas. The indicated flowrate is observed on the flowmeter. The concentration of the inert gas present in the condensed fluid downstream of the flowmeter is measured. This allows a determination of the true flowrate which corresponds to the flowrate indicated by the flowmeter. The method and apparatus of the invention are particularly useful wherein the system is a heat transfer system of a power plant.
