Digital Water Velocity Meter

1 Global Water Flow Probes are highly accurate Water Velocity instruments for measuring flow in open channelsand partially filled pipes. The Water Velocity probe consists of a protected Water turbo prop positive displacementsensor coupled to an expandable probe handle with a Digital readout display. The Water flow Meter incorporatestrue Velocity averaging for the most accurate flow measurements. Use for measuring flows in rivers and streamsand monitoring Velocity in ditches and Digital display in ft/sec or m/sec Records 30 data sets for later analysis Rain-proof Digital computer Highly accurate easy flow monitoring Debris shedding turbo-prop Lightweight, rugged, and reliable Telescoping handle with staff gauge Padded carrying case for easy storage CE Certified Used by Water professionals worldwide for over 12 years Ideal for measuring flows in streams, rivers, canals, stormwater, wastewaterinflow and infiltration studies and industrial process watersCALL GEOTECH TODAY (800) 833-7958 Geotech Environmental Equipment, East 40th Avenue Denver, Colorado 80205(303) 320-4764 (800)

The Turbo-Prop is designed to sheddebris and is protected inside a 2" (5 cm)diameter housing. The probe housing maybe placed directly on the bottom of pipes orstream-beds for measuring low flows downto 2" (5 cm) in depth. The flow Meter pro-peller rotates freely on its shaft with nomechanical interconnections for minimalfriction. The Turbo-Prop, is easily removedfor cleaning or Handle:The Flow Probe handle can telescope from to 6 feet ( to m) (FP111), to 15feet ( to m) (FP211) and to feet(.)

3 7 to m) (FP311) in length. It is construct-ed of anodized aluminum for light weightand long life. The Flow Probe may be easilyextended up to 25 feet ( m) in lengthusing PVC pipe and an extension cable. Thisallows for sewer flow measurements fromstreet level and measuring of stream flowsfrom low bridges. A 3 ft. (.9 m) Mylar coatedstaff gauge (graduated in hundredths of afoot and centimeters) is attached to thelower section of the Water Velocity probe forinstant Water depth measurements andaccurate propeller Velocity Computer:The Water Velocity computer receives anelectrical signal from the propeller, amplifiesthe signal, and converts the reading to feetper second (or meters per second, depend-ing on programming).

4 The large LCD screendisplays average, minimum, and maximumwater Velocity readings. Up to 30 sets of timeand date stamped data points can be storedin the computer with the push of a data points can be reviewed on thecomputer screen for later analysis. The com-puter has a Water -resistant housing andincorporates a unique four-button operationfor changing functions and resetting the dis-play. The Water Velocity computer is pow-ered by a non-replaceable battery that willlast approximately five years with normaluse.
