Global Water Flow Probe Hand-held Flowmeter, 3’ to 6’ Expandable

Ideal for storm run-off studies or flow measurings of rivers, streams, canals, and sewers. Incorporates true velocity averaging for the most accurate measurement possible. The probe shaft is available in lengths that extend from 3’ to 6’ and from 5’ to 15’. Located on the bottom tip is a protected Turbo-Prop sensor which uses the most advanced positive displacement technique available. For minimal friction, this 2” Turbo-Prop sensor rotates freely on a bearing shaft with no mechanical interconnections. Magnetic material in the propeller passes a pickup coil in the housing producing electrical impulses. These electrical impulses are then carried by wire to a readout display on top of the handle. This readout display amplifies and converts the signal into feet/meters per second readings. Instantaneous velocity and true average velocity are then displayed. A unique two-button keypad allows other functions to be displayed including minimum/maximum velocity, time-of-day, timer, totalizer for batch flows, and RPM for accurate low velocity measurement. Features a 30-record memory, padded gun-type carrying case, five-year long life battery for readout display (no battery required for Turbo-Prop), and low battery indicator. Probe can be extended up to 25’ with standard PVC pipe and electrical extension cable. One-year warranty from the manufacturer on the probe and battery.

Have a question about this product?



I wish I had seen all the negative reviews online about this flow-meter before dishing out $1,200+ Propeller fell off after about 12 measurements. No recourse for return of item. Buyer beware!!! DO NOT BUY! YOU WILL REGRET IT! DANGER WILL ROBINSON, DANGER!!!


There is no option for battery change, so the equipment is meant to last only four years!


The product is built well. I have had mine for over three years with no problems. The low battery signal has just come on near 4 years as opposed to the stated 5 years. This would be my only complain about the device as it does not have a replaceable battery the top piece needs to be replaced for a cost of about $300.00. The manufacturer should look into making the top piece with a replaceable battery. The gun case works great unless you drop it in water in which case you should dry it out before storing the device back in the case for any length of time, even a short drive. I have made this mistake and it caused the display to fog up and required the opening up a sealed portion to make the display readable again. I have recommended this device to others and loaned my out multiple time and it is a quick and easy device for all to use.
