LIQ
- Orange Color Band Indicates Liquid State |
| |
VAP
- Blue Color Band Indicates Vapor State |
| |
Use
both color bands if both liquid and vapor may be present. |
4. Print "Ammonia"
in Black Letters on a Yellow Background.
5. Indicate Whether
Internal Pipe Pressure is High or Low.
|
High
- Red Color Band Indicates High Pressure |
| |
Low
- Green Color Band Indicates Low Pressure |
