KROHNE OPTIMASS with MFC 300 EN - Manual (Page 14)

These loads are roughly equivalent to the max axial loading allowed in an un-radiographed butt
weld in a 316L schedule 40 pipe.
Loads given are maximum static loads. If loads are cycling, particularly between tension and
compression, these loads should be reduced.
Please consult KROHNE for more information.
The 3A approval for the 1000 series requires that it is “self draining”. Install the meter vertical-
ly with the flow running uphill.
Installation lengths
For installation lengths, please see section 4.9
Please check with KROHNE if you are unsure of the installation length. Many meters are built
to customer requirements / specifications especially where special hygienic process nectors
have been adapted to the meter. As these are normally non-standard, the installation length
will not be given in the technical data
It is also recommended that the seals be replaced regularly to maintain the hygienic integrity
of the connection.
Unless specifically requested, internal surfaces are not polished and no warranty is made as to
the surface finish.
If polishing option and /or EHEDG, ASME Bio-Processing or 3A approvals was selected at time
of order, all product contact surfaces are polished 0.5 micrometer Ra (20CLa) finish or better.
4.6 Pressure ratings
Meter data plates are stamped with maximum pressure rating at both 20°C (68°F) and max.
operating temperature of connection, primary tube or secondary pressure containment
whichever is the lower.
