Flow measurement in vapors
• Mount the Deltabar M below the measuring point.
• Mount the condensate traps at the same level as the tapping points and at the same
distance to the Deltabar M.
• Prior to commissioning, fill the impulse piping to the height of the condensate traps.
Flow measurement in liquids
• 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.
Installation position for level measurement
Level measurement in an open container
• Mount the Deltabar M below the lower measuring connection so that the impulse piping is
always filled with liquid.
• The low-pressure side is open to atmospheric pressure.
• When measuring in media with solid parts, such as dirty liquids, installing separators and
drain valves is useful for capturing and removing sediment.
Level measurement in a closed container
• Mount the Deltabar M below the lower measuring connection so that the impulse piping is
always filled with liquid.
• Always connect the low-pressure side above the maximum level.
• When measuring in media with solid parts, such as dirty liquids, installing separators and
drain valves is useful for capturing and removing sediment.
Level measurement in a closed container with superimposed steam
• Mount the Deltabar M below the lower measuring connection so that the impulse piping is
always filled with liquid.
• Always connect the low-pressure side above the maximum level.
• A 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.
Installation position for differential pressure measurement
Differential pressure measurement in gases and vapors
• Mount the Deltabar M above the measuring point so that the condensate which may be
present, can run off into the process piping.
• The low-pressure side is open to atmospheric pressure.
• When measuring in media with solid parts, such as dirty liquids, installing separators and
drain valves is useful for capturing and removing sediment.
