Use the following information to help you choose the right flow control valve for your equipment.
​
LIQUID FLOW RATE FORMULA
To calculate liquid flow rates (gpm) so you can pick the correct Flow Control Valve for your application, use the following formula:
​
Width x speed x application rate (gpa) x 0.00202 = gpm
Example: 60 ft. x 15 mph x 20 gpa x 0.00202 = 36.36 gpm

Rotary Flow Meters
​
Rotary flow meters give you accurate flow rates at lower GPM and are typically used in the prewet systems. See below for sizes and flow rates:
​
-
Measure two flow ranges:
-
1/2" flow meter - 4 to 20 gallons per minute (GPM)
-
1/2" with low flow insert - 1.5 to 12 GPM
-
1/4" flow meter - 0.5 to 5 GPM
-
1/4" with low flow insert - 0.1 to 1 GPM
-

1/4" Flow meter - #46649-1170S1
3/8" Turbine Flow Meter
​
The 3/8" flow meter gives you accurate feedback for low flow operations and is perfect for municipal operations that apply at low speeds or low rates.
​
Flow Rate: 0.26-4 GPM
