ABB ProcessMaster FET632 - Processmaster - Material Load for Process Connections; Minimum Permissible Operating Pressure

136 FEP630, FEH630 ELECTROMAGNETIC FLOWMETER | OI/FEP630/FEH630-EN REV. D
… 13 Specification
ProcessMaster – Material load for process connections
The limits of the permissible measuring medium temperature
(T
medium
) and permissible pressure (P
medium
) are calculated on
the basis of the liner and flange material used in the device (see
device name plate).
Minimum permissible operating pressure
The following tables show the permissible minimum operating
pressure (P
medium
) as a function of the measuring medium
temperature (T
medium
) and the liner material.
