2 Minus side is open to the atmospheric pressure
. Mount DPT10 below the lower measurement connection so that
the effective pressure lines are always filled with liquid
. Connect minus side always above the max. level
. 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.
