Global Water FP101 Quick Reference

Quick Reference
Water Velocity Measurement
Maximum & Average Velocities Displayed Digitally
In 8 Languages.
• Factory-calibrated & ready for immediate use:
• Blow on the propeller for 5 – 10 seconds to ensure it turns freely.
• The Flow Probe computer display uses 2 buttons for normal operation:
• Reset the computer display by holding the top button
down for 2 seconds. Instantaneous velocity is always
displayed. Scroll through display modes with the bottom
button to select Average or Maximum speed. Velocity is
displayed in ft/sec or m/sec (Instantaneous velocity to
nearest 0.5, Max to nearest 0.1, Avg to nearest 0.01).
• Orient the propeller directly into the flow
using the arrow indicator aimed
downstream
• With the propeller at your measuring point, hold the probe in
place for several seconds, and then remove the probe. The
Average Velocity reading will hold once the propeller stops turning.
Conversely, move the probe in a smooth vertical motion (as if painting with a brush) to attain
the Average Velocity of a water column.
Some things to be aware of:
Be sure the white end piece is securely snapped into place.
•
While the top of the computer is water resistant, operation
•
can be affected if water gets into the connectors that hold it
to the probe. If the probe head gets wet, remove the white
housing from the probe, separate the computer from the
housing and take out the battery. Allow to dry completely.
