5.4 Secondary Pressure containment
The OPTIMASS 2000 meters are supplied (as standard) without certified housings that have a
typical burst pressure
>
100 barg.
If the user suspects that the primary tube has failed, the unit must be depressurised and
removed from service as soon as it is safe to do so.
Note:
In the 2000 Series there is a high pressure wire feed through with ‘O’ rings that might not be
compatible with the process fluid for an extended period if a primary tube fails.
It is the user’s responsibility to ensure that the materials used are compatible with this prod-
uct.
Other ‘O’ ring materials are available on request.
5.5 Hygienic Applications
The OPTIMASS 2000 (S100) is available with a variety of hygienic process connectors.
When installing / using meters with hygienic process connectors, support /clamp the meter
properly. The meters are heavy and could injure when disconnected from the adjacent pipe
work.
The recommended method of installation is to mount the meter against a support / wall with
the body of the meter supported / clamped. The process pipe work can then be supported off
the meter. The meter is too heavy to be supported from the thin walled piping usually associat-
ed with the hygienic industry. For information regarding lifting the meter, please refer to sec-
tion 3.4.
