Meter Reading
What units does my Graco E-30 meter register in? Liters, pints? I need to know how much I sprayed yesterday?

strokes,,,it measures strokes,,,
and the volume of the stroke is influenced by the size of the cylinder and piston...

look in the drum,,if you sprayed a set and it used say 1500 strokes then you set up a ratio to figure for partial sets

1/1500 = x/strokes on meter cross multiply to solve for x and wammo x becomes the percent of the set you sprayed,,,
or if you sprayed 700 strokes and you get 1500 to a set then solving for x
1/1500 = x/700 = 1500x=700 = x=700/1500 = 60
or 60% of the kit
so if the kit is 100 gallons,,you used 60 gallons

if you paid $$$/1500stks = x$$$/700stks to ratio your fluid costs

aint modern math great!! (and i said i'd never use the stuff when we were learnin it!!)

hope this helps yesman

Or if you haven't modified your e-30,just multiply times .265(100 x .265 = 26.5# of foam).

Maxx, is the E-20 the same x .265?

E-30 = Cycles x .0272 for total output in gallons. Multiply it by 10 for lbs. Divide by 2 for output per side.

E-20 & EXP1 = Cycles x .0104 for total output. Again, multiply by 10 for lbs or divide by 2 for output per side.

E-XP2 = Cycles x .0203 for total output.

H-25/H-40 = Cycles x .063 for total output.

H-XP2/H-XP3 = Cycles x .042 for total output.

These numbers also highlight one of the differences between a hydraulic and electric proportioner. Notice the electrics have to do 2 to 3 times more strokes for the same output? The E-20 has to 6 strokes for every one of the H-25.

MH = .079
A5 = .042
