1.1 Software history
For all GDC devices, the "Electronic Revision" (ER) is consulted to document the revision status
of the electronics according to NE 53. It is easy to see from the ER whether any fault repairs or
major changes to the electronic equipment have taken place and what effect they have had on
compatibility.
Changes and effect on compatibility
1Downwards compatible changes and fault repair with no effect on operation (e.g. spelling
mistakes on display)

3.5 General requirements
3.5.1 Vibration
INFORMATION!
To assure a quick, safe and uncomplicated installation, we kindly request you to make provisions
as stated below.
INFORMATION!
The following precautions must be taken to ensure reliable installation.
• Make sure that there is adequate space to the sides.
• Protect the signal converter from direct sunlight and install a sun shade if necessary.
• Signal converters installed in control cabinets require adequate cooling, e.g. by fan or heat
exchanger.
• Do not expose the signal converter to intense vibration. The flowmeters are tested for a
vibration level in accordance with IEC 68-2-6.
