KROHNE OPTIMASS with MFC 300 EN - Manual (Page 27)

Meter data plates are stamped with maximum pressure rating at both 20°C (68°F) and maxi-
mum operating temperature of connection or primary tube, whichever is the lower.
Maximum pipe work forces
These loads are roughly equivalent to the max axial loading allowed in an un-radiographed butt
weld in a 316L schedule 80 pipe.
Loads given maximum static loads. If loads are cycling, particularly between tension and com-
pression then these loads should be reduced.
Please consult KROHNE for more information.
The 3A approval for the 2000 series requires that it is “self draining”. Therefore, the meter
MUST be installed vertically with the flow running uphill.
Installation lengths
For installation lengths, please see section 5.9
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.
