• Mount the measuring 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
