Nozzle Flow Check

A - Tests Drop-Down Menu

B - Test Speed Input Box

C - Rate Input Box

D - Enable Pump Checkbox

E - Master Switch Indicator

F - Start Nozzle Flow Check Button

G - Rate

H - Pressure

I - Flow

• If the actual application rate can meet the target application rate at a given speed.

• The actual flow rate in lpm (gpm) out of the implement section.

• Whether the nozzles are worn.

• The pressure at the spray control valves given a desired speed and application rate.

1. IMPORTANT: Always fill the solution tank with clean water to do a proper nozzle flow check.

   NOTE: Turn Master Switch OFF at any time to cancel test.

   Use conditions in this test that are comparable to normal operation. Larger dispense volumes will result in longer, but more accurate, calibration tests.

   Select Nozzle Flow Check from the tests drop-down menu.

2. Enter a Test Speed such as 10 km/h (6.2 mph).

3. Enter a desired spray "Rate" such a 94 l/hec (10 gal/ac).

4. Set pump to normal operating speed.

5. Turn the Master Switch ON.

6. Check Enable Pump checkbox (D) if it is displayed.

   NOTE: Enable Pump Checkbox (D) will only be displayed if control valve type is PWM and Pump Enable checkbox was selected in PWM settings.

7. Select the Start button on the screen.

   NOTE: Speed and rate can be changed while test is running.

8. If the volume is higher than expected and pressure is lower than expected, nozzle tips could be worn.

   If the pressure is higher than expected for the given output, nozzle tips could be partially plugged. Also, a pressure drop could be occurring from the section shut-off valves to nozzle tips (normally only associated with high flow rates.)
