The Flow

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.

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.
