APPENDIX 8
PROCEDURE TO RE-CALIBRATE FLOW METER
1)
Enter a LIQ METER CAL number of 10 [38] in
.
2)
Enter a TOTAL LIQ VOLUME of 0 in
.
3)
Place MASTER switch to OFF.
4)
Remove hose and place in calibrated 5 gallon [19 liter] container.
5)
Place POWER switch to GR/LI and MASTER switch to ON. Enter a self test speed
of 5 mph. Pump exactly 10 gallons [38 liters].
6)
Readout in DATA display is the new METER CAL number. This number should be
/-3% of the number stamped on the tag on Flow Meter.
7)
Repeat this procedure several times to confirm accuracy. (Always "zero out"
the TOTAL LIQ VOLUME display before retesting).
NOTE: For greatest precision, set METER CAL to 100 and pump 100 gallons (378
liters) of water.
8)
To verify Flow Meter calibration, fill applicator tank with a predetermined
amount of measured liquid (i.e. 250 gallons). DO NOT RELY ON GRADUATION NUMBERS
MOLDED INTO APPLICATOR TANK. Empty the applicator tank under normal operating
conditions. If the number displayed under TOTAL LIQ VOLUME is different from
the predetermined amount of measured liquid by more than +/-3%, complete the
following calculation.
EXAMPLE:
LIQ METER CAL
= 720 [190]
TOTAL LIQ VOLUME
= 260 [984]
Predetermined amount of measured liquid
= 250 [946]
Corrected METER CAL
= LIQ METER CAL x TOTAL LIQ VOLUME
Predetermined amount of measured liquid
ENGLISH UNITS:
METRIC UNITS:
= 720 x 260 = 749
= [190] x [984] = [198]
250
[946]
Corrected LIQ METER CAL = 749 [198]
9)
Enter corrected LIQ METER CAL before resuming application.
NOTE: For RFM 200 series Flow Meter, use old METER CAL number of 164 [43] and
calibrate as described in Step 8.
