Installation instructions
• To ensure optimal readability of the local display, adjust the housing and local display
• Hauser offers a mounting bracket to mount the device on pipes or walls
• When measuring in media containing solids (e.g. dirty liquids), installing separators and
drain valves is useful for capturing and removing sediment
• Using a valve manifold allows for easy commissioning, installation and maintenance
without interrupting the process
• When mounting the device, establishing the electrical connection and during operation:
prevent the penetration of moisture into the housing
• Point the cable and plug downwards as much as possible to prevent moisture from entering
(e.g. rainwater or condensation)
5.1.3
Installing pressure piping
• For recommendations for routing pressure piping, refer to DIN 19210 "Differential pressure
piping for flow measurement devices" or the corresponding national or international
standards
• When routing the pressure piping outdoors, ensure sufficient anti-freeze protection, e.g. by
using pipe heat tracing
• Install the pressure piping with a monotonic gradient of at least 10%

Mounting the device
5.2.1
Flow measurement
Flow measurement in gases
Mount the device above the measuring point so that condensate can drain into the process
pipe.
Flow measurement in vapors
• Mount the device below the measuring point
• Mount the condensate traps at the same height as the tapping points and at the same
distance to the device
• Prior to commissioning, fill the piping to the height of the condensate traps
Flow measurement in liquids
• Mount the device below the measuring point so that the piping is always filled with liquid
and gas bubbles can run back into the process pipe
• When measuring in media with solid parts, such as dirty liquids, installing separators and
drain valves is useful for capturing and removing sediment
