Note for Closing Flow |
N/A
Based on horizontal installation of excess flow valve. Flows are slightly more when valves are installed with outlet up; slightly less when installed with outlet down. |
Note |
N/A
Multiply flow rate by 0.94 to determine liquid butane flow and by 0.90 to determine liquid anhydrous ammonia flow. |
