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
Group 1 or 2
•
Aggregate state
Liquid or gaseous
•
Type of pressurized equipment
–
Pipeline
Product of pressure and volume (PS * V [barL])
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.
Division of media (liquid/gaseous) into the fluid groups
Fluids are divided according to Article 9 into the following fluid groups:
Group 1 fluids
Explosive
R phrases: for example: 2, 3 (1, 4, 5, 6, 9, 16, 18,
19, 44)
Very toxic
R phrases: for example: 26, 27, 28, 39 (32)
