Flow measurement in steam
P01-PMD55xxx-11-xx-xx-xx-001
Measuring layout for flow measurement in steam
1 Condensate traps
2 Orifice plate or pitot tube
3 Shut-off valves
4Deltabar M
5Separator
6 Drain valves
7 Three-valve manifold
• 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
P01-PMD55xxx-11-xx-xx-xx-002
Measuring layout for flow measurement in liquids
1 Orifice plate or pitot tube
2 Shut-off valves
3Deltabar M
4Separator
5 Drain valves
6 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.
