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
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
