GLOBAL WATER FP 111 - Digital water velocity meter
Flow Probe Product Description
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 water 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 inch diameter housing. The probe housing may be
placed directly on the bottom of a pipe or streambed for measuring low
flows down to 2 inches 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. NOTE:
Global Water recommends recalibrating the water velocity computer every
time the Turbo-Prob sensor is replaced. Contact our Technical Support
department for more details.
Water Velocity Computer
The water velocity computer receives an electrical signal from the
propeller, amplifies the signal, and converts the reading
