ABSTRACT:
An accurate amount of a chemical concentrate is injected and mixed into a pressurized carrier liquid stream and dispensed by employment of two calibrated in-line valves in the line siphoning the concentrate to a siphon injector. The valves are so calibrated that the operator need only set the first in-line valve at the percentage of active ingredient in the concentrate and set the second valve at the percentage of active ingredient desired in the mixture to precisely reduce the flow rate of the concentrate in the siphon line and provide an accurately mixed finished liquid at the dispensing end of the system. Such a system is particularly adapted for use in the pest control industry.
