GLOBAL FLOW PROBE 3' - 6' Get Quote



The Global Flow Probe is a highly accurate water velocity instrument for measuring flow in open channels and partially filled pipes. It is ideal for stormwater runoff studies and measuring flow in rivers, streams, ditches and sewers. The probe housing can be placed directly on the bottom of a pipe or stream bed to measure low flows down to one-and-a-half inches in depth. The Flow Probe uses true velocity averaging. When the probe is put into flowing water, a running average is started. As long as the probe remains in the flow, averaging continues until it is steady reading. When the probe is pulled from the water, the average value is frozen on the display until reset.
