à Mount VEGADIF 55 below the lower measurement connection so
that the effective pressure lines are always filled with liquid
à Connect minus side always above the max. level
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.
