Installation conditions
5.1.1
General instructions
• Do not clean or touch process membrane with hard and/or pointed objects
• Do not remove process membrane protection until shortly before installation
Always firmly tighten the housing cover and the cable entries.
1. Counter-tighten the cable entries.
2. Tighten the coupling nut.
5.1.2
Installation instructions
• A position-dependent zero point shift (when the vessel is empty the measured value
does not display zero) can be corrected
• To ensure optimum readability of the onsite display, rotate the housing and onsite
display
• Hauser offers a mounting bracket for installing the measuring 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 connector downwards as much as possible to prevent the
penetration of moisture (e.g. rain water 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%
5.1.4
Orientation
The orientation depends on how the impulse lines are connected.
