Installation and Operating Instructions OPTIMASS 9
1.2 OPTIMASS 7000 Single Straight Tube Meter
1.2.1 Specific Installation Guidelines
• Tighten flange bolts evenly.
• Observe min and max pipe end loads at end of this section.
The use of reducers at the flanges is
allowed. Extreme pipe size reductions
should be avoided due to possibility of
cavitation and degassing.
There are no additional installation requirements for the OPTIMASS 7000 sensors. Fixing of flexible
hoses directly on the meter is allowed.
1.2.2 Ambient / Process temperatures
The specified and approved ambient and process temperatures must be observed.

Note:
Where meters are mounted in direct sunlight, it is recommended to install a sunshade. This is
particularly important in countries with high ambient temperatures.
The maximum differential temperature between the process and ambient temperature without
insulation is 130°C or 265°F for Titanium and 80°C or 115°F for Hastelloy and Stainless Steel meters.
