• Mount the device below the lower measuring connection so that the piping is always
filled with liquid
• Always connect the low-pressure side above the maximum level
• The condensate trap ensures constant pressure on the low-pressure side
• When measuring in media with solid parts, such as dirty liquids, installing separators
and drain valves is useful for capturing and removing sediment

• Mount the device above the measuring point so that the condensate can drain into the
process pipe
• The negative side is open to atmospheric pressure via the screwed-in reference air filter
of the side flange on the low-pressure side
