1.1 Software History

The "Electronic Revision" (ER) is consulted to document the revision status of electronic equipment according to NE 53 for all GDC devices. It is easy to see from the ER whether troubleshooting or larger changes in the electronic equipment have taken place and how that has affected the compatibility.

Changes and effect on compatibility

1	Downwards compatible changes and fault repair with no effect on operation (e.g. spelling
	mistakes on display)
2-_	Downwards compatible hardware and/or software change of interfaces:
	H	HART®
	P	PROFIBUS
	F	Foundation Fieldbus
	M	Modbus
	X	all interfaces
3-_	Downwards compatible hardware and/or software change of inputs and outputs:
	I	Current output
	F, P	Frequency / pulse output
	S	Status output
	C	control input
	CI	Current input
	X	all inputs and outputs
4	Downwards compatible changes with new functions
5	Incompatible changes, i.e. electronic equipment must be changed.

INFORMATION!

In the table below, "x" is a placeholder for possible multi-digit alphanumeric combinations, depending on the available version.

2.2 Device description

The mass flowmeters are designed exclusively to directly measure mass flow rates, product density and temperature as well to indirectly measure parameters such as the total volume and concentration of dissolved substances as well as the volume flow rate.

Your measuring device is supplied ready for operation. The factory settings for the operating data have been made in accordance with your order specifications.

The following versions are available:

•Compact version (the signal converter is mounted directly on the measuring sensor)

•Remote version (electrical connection to the measuring sensor via field current and signal cable)
