• Mount the measuring device below the measuring point
• Mount the condensate traps at the same level as the tapping points and at the same
distance to the measuring device
• Prior to commissioning, fill the piping to the height of the condensate traps

6 Drain valves
• Mount the measuring device below the measuring point so that the 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
