DIN EN 12178:2004 Refrigerating systems and heat pumps - Liquid level indicating devices - Requirements, testing and marking; German version EN 12178:2003
This European standard describes requirements and tests for liquid level indicating devices used in refrigerating systems and heat pumps. It applies to devices connected to refrigerant vessels (e. g. on high-pressure liquid receivers, intercoolers and low-pressure separators) and to devices connected to other parts of a refrigerating system (e. g. oil-level sight glasses on a compressor).#,,#
