Hauser
Pressure measuring device
approval
The measuring devices can be ordered with or without PED (Pressure Equipment Directive). If a
device with PED is required, this must be ordered explicitly. For devices with nominal diameters
less than or equal to DN 25 (1"), this is neither possible nor necessary.
• With the identification PED/G1/III on the sensor nameplate, Hauser confirms
conformity with the "Basic 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 or less than 0.5 bar (7.3 psi)
– Unstable gases
• 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.
Measuring device approval
The measuring device is approved as a cold water meter (MI-001) for volume measurement for
operation subject to legal metrological control in accordance with the European Measuring
Instruments Directive 2004/22/EC (MID) - type-examination certificate DE-07-MI001-PTB014.
The device is qualified to OIML R49, with an associated OIML Test Report.
