The Apparatus Flow Test Kit (AFTK) uses the pitot method to measure water flow.

This is where the flow is the direct function of the stream velocity (pressure) through a nozzle tip of known diameter. One way to read nozzle tip pressure, accurately, is to place the pitot tube tip securely in the center of the discharge tip diameter and parallel to the direction of the water flow. The pitot simply measures the flowing water pressure at the point of pick up and is read in PSI on the pressure gauge. The enclosed Akron Brass Straight Bore Discharge Data chart converts the PSI reading to the actual flow in GPM.
