1.5 Pressure Equipment Directive (PED)
To ensure the PED integrity of the meter, you MUST check that the serial numbers on the
converter nameplate and the sensor nameplate are the same.
To comply with the requirements of the Pressure Equipment Directive (PED) the manufacturer
provides all the relevant technical data in the technical data section of this handbook. In addition
to which, the following should also be noted:
• Secondary pressure containment is supplied as standard.
• The PED / CRN approved secondary containment pressure is 30 barg / 435 psig at
20°C / 68°F.
• The wiring feedthrough is made of Epoxy, PPS or PEEK with two O-rings made from FPM /
FKM & Hydrogenated Nitrile.
• If the measuring tube/s fails, the O-ring will be in contact with the process product.
• You MUST make sure that the O-ring material is suitable for the application.
• Alternative O-ring materials are available on request.
Secondary pressure containment
Secondary pressure containment is subject to de-rating according to temperature. Refer to the
de-rating graphs shown in the relevant section.
If a heating jacket is fitted, secondary pressure containment is limited to 10 barg / 145 psig at
20°C / 68°F
Where the meter is being used to measure high pressure gases and / or gases kept as liquids by
high pressure and / or where there is a risk of tube failure because of the use of corrosive or
erosive fluids, frequent pressure and / or thermal shock, seismic or other shock loading, a
secondary containment option MUST be purchased
Where the above situation applies and the process pressure exceeds the secondary pressure
containment (please refer to technical data) or where secondary pressure containment is not
available, the burst disc option MUST also be purchased. For more information, please contact
your nearest representative.
The burst disc option is not available if the heating jacket option has been ordered.
LEGAL NOTICE!
The Pressure Equipment Directive places legal requirements on both the manufacturer and the
end user. Please read this section carefully!
