D. Injection Adjustment:
Chemical feed rates are controlled by metering tips screwed into the proportioner barb. Use Table 1 for 1 GPM proportioner
and Table 2 for 4 GPM proportioner as a guide for tip selection.
1 cps (centipoise) is equal to the viscosity of water
75 cps is approximately equal to the viscosity of 10 weight motor oil
200 cps is approximately equal to the viscosity of most dishwashing detergents

All induction rates are based on a water pressure of 40 psi.
Leaner dilutions can be achieved by ordering DEMA ultra lean tip kit 100-15KU or capillary tip 44-61P.
