PED

The pressure equipment directive 97/23/EC applies to the alignment of the statutory orders
of the European member states for pressure equipment. Such equipment in the sense of the
directive includes vessels, pipelines and accessories with a maximum allowable pressure of
more than 0.5 bar above atmospheric. Flowmeters are considered as piping.
A detailed risk analysis of the flowmeter has been performed in accordance with the PED
97/23/EC. All risks are assessed to be "none" provided that the procedures and standards
referenced in these operating instructions are observed.
Division according to the danger potential
Flowmeters, which are categorized as piping, are divided into categories according to danger
potential (medium, pressure, nominal diameter). The flowmeters fall into the categories I to
III or they are manufactured according to Article 3 Paragraph 3 - Sound Engineering Practice
(SEP).
The following criteria are decisive for assessment of the danger potential, and are also
shown in Diagrams 6 to 9.
Fluid group
• Aggregate state
• Type of pressurized equipment
– Pipeline
The maximum allowable temperature for the used liquids or gases is the maximum process
temperature which can occur, as defined by the user. This must be within the limits defined
for the equipment.
