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 NOT supplied as standard.
• The non PED / CRN approved outer cyclinder has a typical burst pressure greater than
100 barg / 1450 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 and feedthrough will be in contact with the process
product.
• You MUST make sure that the O-ring and feedthrough material is suitable for the application.
• Alternative O-ring materials are available on request.
Secondary pressure containment
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 cycling, seismic or other shock loading, a
secondary containment option MUST be purchased

DANGER!
If it is suspected that the primary measuring tube has failed, de-pressurise the meter and
remove it from service as soon as it is safe to do so. Where the meter has a Tantalum primary
measuring tube, extra care MUST be taken because the process fluid might be highly toxic and /
or corrosive to the outer cylinder, wiring feedthrough and O-rings.
