A range of perforated tank tags for quick tear-off and to help identify tank levels from a distance. These tank tags from Vantage Tags come in different colours, sizes and shapes to make them easily visible. Different tag colours are used to identify and differentiate the contents of one tank from another. The perforation will also inform whether the tank is full, in use, or empty and due to be refilled. They also contain fields so that additional information can be recorded such as when a tank was last inspected or serviced.
