1.
Unplug the flowmeter. With voltmeter, check for
12 volts between Power & Ground
of flowmeter connector.
Should have
4
-
5 volts between signal and ground
. If voltage is not present, inspect wiring harness and check for
voltage at harness connection(s) nearer the Rate Controller (at 12
-
pin Deutsch connector, Power is 1, Ground is 2,
Flow Signal is 3).
2.
If 12 volts is present, then conduct a
tap test
. Go to
Setup
> Settings > Flow/Rate Sensor Setup
and change the
flow cal to 1. Have a second person watch GPM on the 1,2,3 screen while other person taps repeatedly (use a short
piece of wire or a paper clip) between signal and ground pins of flowmeter connector. A flow value (gpm) should
show up indicating the wiring is not damaged. (If alone, note or reset a volume counter to 0, and start Calibrate
PWM Limits Test. Check for increased volume after tapping.)
3.
If the flow showed on the display during the tap test, your wiring to that point is good. If tap test did not work, go back
to the next harness connection and do a tap test there between signal and ground.
4.
If the tap test registers flow on the display, replace flowmeter. (
Sometimes, cleaning the inside tube of the flowmeter
with soapy water and a soft brush will remove a film covering the electrodes.)
5.
Change Flow Cal back to appropriate Flow Cal when finished with Tap Test.
6.
SureFire has a Speed/Flow Simulator (PN 219
-
01462) or a Tap Tester (212
-
03
-
3912Y1) that can be used to
confirm if the wiring is good between the flowmeter and controller.
Field Verification of Flowmeter Calibration
Always verify the flow cal setting by comparing the amount actually applied in the field (from weigh tickets)
with the amount shown on the display. Adjust the flow cal as needed to get less than 1% difference between
the actual amount applied and the amount shown on the display.
In general:
Increase the Flow Cal number if not enough product is actually being applied.
(If you want more,
increase the number)
Decrease the Flow Cal number if too much product is being applied. (
If you want less, decrease the
number)
Formula to Adjust Flow Cal Number
(Volume shown on display) / (Volume actually applied) X flow cal number in display = new flow cal
Example: Display shows 727 gallons was applied. Weigh ticket shows 750 gallons was actually applied.
Flow cal number in display was 3000.
(We applied too much, so we will decrease the flow cal.)
727
/ 750 X 3000 = 2908 (new flow cal number to set in display)
(
Any adjustments to the flow cal number will only be as accurate as the measurements used in figuring it.)
Do not power wash the flowmeter.
Unplug the flowmeter before welding on the implement.
Remove red guard to reach pins. Don
’
t break red side clips.
