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 1000 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-

4.5 Hygienic Applications
The OPTIMASS 1000 series 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 associ-
ated with the hygienic industry
