8.3 Pressure Equipment Directive (PED) Requirements.
To comply with the requirements of the PED in Europe, the following information is provided to
assist the plant engineer in installing the meter.
Measuring tube:
Stainless SS 316L
Sealing Faces:
Stainless SS 316L
Hastelloy C22 Hastelloy C22
Flanges: SS 316L Casing: Stainless Steel 304
Typical burst pressure of casing is in excess of 50
bar @ 20°C. Not PED approved
Insulation is strongly recommended above 100°C
Repeated heating or cooling at rates > 30°C per hour should be avoided to increase operational
lifespan of meter.
8.4 Secondary Pressure Containment
The OPTIMASS 8000/9000 series sensors do not have certified secondary containment.
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.
8.5 Pressure De-Rating
Meter data plates are stamped with maximum pressure rating (at 20ºC and max. operating
temperature) of connection or primary tube (whichever is the lower).
