A typical fire sprinkler design requires 26 gpm, which is fine for 3/4-inch and 1-inch meters, but exceeds the maximum flow for 5/8-inch meters. One solution would be to use low-flow sprinkler heads to lower the system demand at or below 20 gpm.
How do you calculate the flow rate of a commercial fire sprinkler system?
