5.1.2 Installation instructions
• To ensure optimal readability of the local display, adjust the housing and local display
• Endress+Hauser offers a mounting bracket to mount the device on pipes or walls
• Use flushing rings for flanges, flange seals and pancake seals if buildup or clogging can
be expected at the membrane
• The flushing ring is clamped between the process connection and the flange, flange
seal or pancake seal
• Material buildup in front of the membrane is flushed away, and the pressure chamber
is vented, via the two lateral flushing holes
• 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)
