PROFIBUS DP/PA
certification The flowmeter has successfully passed all the test procedures carried out and is certified and
registered by the PNO (PROFIBUS User Organization). The device thus meets all the
requirements of the following specifications:
• Certified in accordance with PROFIBUS Profile Version 3.0 (device certification number:
available on request)
• The device can also be operated in conjunction with other-make certified devices
(interoperability).
Pressure measuring
device approval • With the identification PED/G1/x (x = category) on the sensor nameplate,
Hauser confirms conformity with the "Essential safety requirements" of Appendix
I of the Pressure Equipment Directive 97/23/EC.
• Devices with this identification (with PED) are suitable for the following types of fluid:
Fluids of Group 1 and 2 with a steam pressure of greater than, or smaller and equal to 0.5
bar (7.3 psi).
• Devices without this identification (without PED) are designed and manufactured
according to good engineering practice. They correspond to the requirements of Art. 3,
Section 3 of the Pressure Equipment Directive 97/23/EC. Their application is illustrated in
Diagrams 6 to 9 in Appendix II of the Pressure Equipment Directive 97/23/EC.
Oxygen service For oxygen applications with the order code for "Surface cleaning" option B "Certified and
cleaned of oil and grease"
We certify that the wetted parts of the flow sensor have been degreased in accordance with
British Oxygen Company (BOC) specification 50000810 and BS-IEC-60877:1999. After
final degreasing there shall be less than 100 milligram/m² (0.01 milligram/cm²) of oil/
grease contamination on the degreased surface of the component.
