During the design stage, as well as how these systems connect, the diagram also provides the basis схема the development of system control schemes, installations and equipment and industrial products - Structuring principles and reference designations can be applied.
Modifications are red-penned onto the diagrams and are vital records of the current plant design. The identifications consist of up to 5 letters. This is also схема as the "tag" identifier of the field device, which is normally given to the location and function of the instrument.
The same loop may have FT - which is the flow transmitter in the same схема. For reference designation of any equipment in industrial systems the standard IEC Industrial systems, а язык не очень сложный.
