Page 89: Wet/Dry Measurement Deviations, Conversion Table
Wet/Dry Measurement Deviations, Conversion Table NOTICE The LT3-F carries out measurements directly in the humid flue gases (wet measurement). When extractive devices are used, flue gases are removed and prepared. "Dry measure- ments" are normally used here, since the humidity has been extracted from the flue gas. As a result, O measurement values vary (see diagrams below). - Page 90 The information in this publication is subject to technical changes. LAMTEC Meß- und Regeltechnik für Feuerungen GmbH & Co.
