1. Mount VEGADIF 65 below the lower measurement connection so
that the effective pressure lines are always filled with liquid
2. Connect minus side always above the max. level
3. 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.
