1. Mount VEGADIF 65 below the measurement loop so that the ef-
fective pressure lines are always filled with liquid and gas bubbles
can bubble up to the process line
2. For measurements in products with solid content such as e.g.
dirty liquids, the installation of separators and drain valves is
recommended to enable collection and removal of debris and
sediment.
