The new digital meters will often show a “flow rate” displayed with some numerical value ranging from zero on up. Most flow rates are based on Cubic Feet (CF) Per Minute. Given that one CF = 7.48 gallons, simply multiply the value for “flow rate” times 7.48 and this will translate to Gallons Per Minute (GPM). For example, a flow rate value of .02 will calculate as follows: .02 X 7.48 = .15 GPM
