GLOBAL WATER FP111 Flow From Velocity Meter : The Flow Probe uses true velocity averaging. To start a running average, first hold the reset button for 3 seconds to zero the display. When the probe is placed in the water flow, an average will begin. As long as thewater velocity sensor remains in the flow, the averaging continues. Once the average reading becomes steady, the true average velocity has been obtained. When you remove the Flow Probe from the water, the average value is frozen on the display until reset.
