1. Mount VEGADIF 65 below the lower measurement connection so
that the effective pressure lines are always filled with liquid
2. Minus side is open to the atmospheric pressure
3. When measuring liquids with solid content, the mounting of sepa-
rators and drain valves is useful to be able to avoid and remove
buildup.
