à Mount VEGADIF 55 below the measurement loop so that the
effective pressure lines are always filled with liquid and gas
bubbles can bubble up to the process line
à 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.
à Fill the effective pressure lines to the height of the condensate
vessels before setup
