Flow Probe Product Description
The Flow Probe's Turbo-Prop
|
The Flow Probe's Digital Readout Display
|
The Global Water Flow Probe is a highly accurate water velocity instrument for measuring
flows in open channels and partially filled pipes. The water velocity probe consists of a protected water turbo prop positive
displacement sensor coupled with an expandable probe handle ending in a digital readout display. The water flow meter
incorporates true velocity averaging for the most accurate flow measurements. The Flow Probe is ideal for storm water
runoff studies, sewer flow measurements, measuring flows in rivers and streams, and monitoring velocity in ditches and canals.
Turbo-Prop Sensor
The Flow Probe incorporates the unique Turbo-Prop propeller sensor, which uses the most accurate positive displacement
technique available for velocity sensing. The Turbo-Prop is designed to shed debris and is protected inside a 2"
diameter housing. The probe housing may be placed directly on the bottom of a pipe or streambed for measuring low
flows down to 2" in depth. The flow meter propeller rotates freely on its bearing shaft with no mechanical
interconnections for minimal friction. Magnetic material in the propeller tip passes a pickup point in the water velocity
meter handle producing electrical impulses that are carried to the readout display by an internal cable. The Turbo-Prop
is easily removed for cleaning or replacement.
Digital Readout Display
The Digital Readout Display receives an electrical signal from the propeller, amplifies the signal, and converts the reading to feet
per second (or meters per second, depending on programming). The readout displays instantaneous velocity and true
average velocity. The readout unit is water-resistant and incorporates a unique two-button operation for changing functions
and zeroing the display. An internal watch-type battery powers the unit continuously for one year and is easily
replaced. Also available on the readout is maximum velocity, time-of-day, and stopwatch functions.

Flow Probe Handle
The Flow Probe handle can telesope from 3 feet to 6 feet in length (FP101) or 5 feet to 15 feet (FP201). The handle is
constructed of anodized aluminum for light weight and long life. The Flow Probe may be easily extended up to 25 feet in
length using standard PVC pipe and an electrical extension cable. This allows for measuring sewer flows from street level
and measuring stream flows from low bridges. A 3-foot mylar coated staff gauge (graduated in hundredths of a foot and
centimeters) is attached to the lower section of the water velocity probe for instant water depth measurements and accurate
propeller positioning.
True Velocity Averaging
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 the water 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.
Optional Swivel Head
The Flow Probe Swivel Head option allows you to rotate the flow probe's turbo prop to + 90 degrees from it's standard position. This
option lets the flow probe take water velocity measurements in hard to measure areas such as vertical pipes on water tanks or swimming pool
drainage systems.
