Worn Nozzles & Flow Table
Information
1.
Determine nozzle size and desired spraying pres-
sure using this application guide.
2.
Find fluid ounces per minute (OPM) in Table #3 or
Table #4.
3.
Catch flow at pressure desired for 1 minute {for large
nozzles catch the flow for 30 seconds and multiply
by 2}.
4.
If the OPM caught are within the
+
limit in the chart
on page 31, the nozzle is accurate and G.P.A. charts
should be followed.
5.
If the nozzle is not within the
+
limit, check for ob-
structions or wear in the orifices of the nozzle. Take
the cap off the nozzle, clean the orifices with a tooth-
pick or brush and retest. If several nozzles test the
same, but are not within the
+
limits, a faulty gauge
may be the problem. If two or more nozzles are out-
side the limit, it is a good indication that all your noz-
zles may be worn. In this case, it would be advisable
to replace ALL the nozzles with new nozzles.
