Chemical feed rates are controlled by metering tips screwed into the inlet barb. Injection rates for various settings and for products of
different viscosities are as follows:
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
