Global Water 800-876-1172 • globalw.com I. Flow Probe Checklist a. Flow Probe b. Flow Probe Manual II. Inspection a. Your Flow Probe was carefully inspected and certified by our Quality Assurance Team before shipping. If any damage has occurred during shipping, please notify Global Water Instrumentation, Inc. and file a claim with the carrier involved. Use the checklist to ensure that you have received everything needed to operate the Flow Probe.
Global Water 800-876-1172 • globalw.com III. General Instructions a. Make sure the Flow Probe’s propeller turns freely by blowing strongly on the prop. b. Point the propeller directly into the flow you wish to measure. Face the arrow inside the prop housing downstream. The FP101 probe handle is a two piece rod expandable from 3’ to 6’, and the FP201 is a three section rod expandable from 5’ to 15’.
Global Water 800-876-1172 • globalw.com f. The average velocity (calculated with the Flow Probe in feet/second) times the cross-sectional area (square feet) equals flow in cubic feet per second (cfs), or Q = V x A. g. If the propeller gets fouled while measuring flow, clean it until the prop turns freely and start over. IV. Average Velocity The Flow Probe is used to measure the average water velocity. Streamflow velocity varies for two reasons: a. The velocities vary throughout the flow’s cross-section.
Global Water 800-876-1172 • globalw.com The Flow Probe uses true velocity averaging. When the average and maximum velocities are zeroed by pushing the top button, a running average is started. As long as the probe remains in the flow, the averaging continues. One reading is taken per second, and a continuous average is displayed. For example, after 10 seconds, 10 readings are totaled and then divided by 10 and this average is displayed.
Global Water 800-876-1172 • globalw.com V. Computer Operation a. The Flow Probe is calibrated at the factory. When you receive the product, you may wish to set the computer’s clock (see Computer Setup), otherwise you should not have to alter any of your computer settings. You will have to recalibrate the computer when you change the unit’s battery (See Appendix A: Computer Setup). Normal battery life for the Flow Probe is 3 years or more. b. The Flow Probe computer has a simple 2-button operation.

After replacing battery the calibration numbers will require resetting. (See Appendix A: Computer Setup) c. Cleaning: Make sure the Turbo Prop turns freely before and after your measurements. Blow on the prop in the direction of flow. The prop should turn freely.
Global Water 800-876-1172 • globalw.com VIII. Trouble Shooting Issue: Computer reading incorrectly a. Blow on the propeller. The prop should spin freely and make a noise (chatter) when you blow on it. The prop should be loose on the shaft when you push it with your finger. If prop does not spin freely, rinse it with clean water or soak it in mild soapy water. b. A small metal magnet covered with clear adhesive is installed on the back side of the prop on one blade.

Global Water 800-876-1172 • globalw.com X. Appendix A: Computer Setup The BC1200 has the capability to switch between 2 different calibration factors. To change between the calibrations remove the computer from the flow probe head by twisting 45 degrees counter clockwise and lifting. The indented gray button in the upper left corner on the back is to switch between CAL I and CAL II. In the upper left corner of the display, I is displayed for CAL I and II is displayed for CAL II.
Global Water 800-876-1172 • globalw.com (NOTE: after battery replacement and additional screen displaying SET ODO will follow the forth digit of the cal number. Ignore this and press the indented gray button to store settings) TO SET CLOCK • Press bottom button until clock appears at the bottom of the screen. • Turn computer over and press and hold the right indented gray set button (S) for 5 seconds or until clock flashes. • Press top button until hour is reached.
