• Mount the Deltabar M above the measuring point so that the condensate which may be present,
can run off into the process piping.

Three-valve manifold
• Mount the Deltabar M below the measuring point so that the impulse piping is always filled with
liquid and gas bubbles can run back into the process piping.
• When measuring in media with solid parts, such as dirty liquids, installing separators and drain
valves is useful for capturing and removing sediment.
