RECALIBRATING THE FLOW METER
To calibrate the flow meter:
1. Fill the applicator tank with clean water.
2. Open the UT Menu and select the Hawkeye menu button.
3. From the home screen, select the Tools Menu softkey along the right side of the display.
4. Select the System Settings tab along the top of the display and select the Product Control Settings button.
5. Enter a value of 10 [38] for the meter cal.
6. Select the Home softkey along the right side of the display and then select the Tally Registers softkey.
7. Enter a value of zero for the total volume value.
8. Toggle the master switch and all boom sections to the off positions.
9. Remove a section hose and place it into a calibrated five gallon [19 liter] container.
10. Toggle the master switch and the boom switch corresponding to the hose that was placed in the container.
11. Pump exactly ten gallons [38 liters] of water to fill the container twice.
12. Check the total volume registered on the UT tally registers prompt. The reading displayed is the new meter cal
value. This value should be within ± 3% of the calibration number stamped on the tag of the flow meter.
13. Repeat this procedure several times to confirm accuracy. Always “zero out” the total volume display before
retesting.
NOTE: For increased precision, set meter cal to 100 [378] and pump 100 gallons (378 liters) of water.
14. To verify the flow meter calibration, the fill applicator tank with a predetermined amount of measured liquid
(i.e. 250 gallons [946.4 L]).
NOTE: Do not rely on graduation marks molded into the applicator tank.
15. Empty the applicator tank under normal operating conditions.
If the total volume displayed is different from the predetermined amount of measured liquid by more than ±
3%, complete the following calculation:
Where CMC = the Corrected Meter Cal, MC = the Meter Cal used to apply the known volume, and VM = the
Volume measured by the UT tally registers prompt, and VA = the predetermined volume applied.
FOR EXAMPLE:
The UT displays a Total Volume of 260 [984] when a Meter Cal of 720 [190] was used to apply a measured
volume of 250 gallons [946 liters]. Therefore:
the Corrected Meter Cal is 749 [198]
16. Return to the Product Control Settings prompt and enter a value of 749 [198] for the meter cal.
