Abstract: A method of using a fluid injector in fluid communication with a fluid flow line where flow is transferred from the flow line into the fluid injector and back to the fluid flow line. An inlet flow is used to pressurize the storage tank and provide a solution to mix with injection solutions in the tank.

Abstract: A fluid injector made of pressure rated components that attach to a fluid flow line so that flow is transferred from the flow line, into the injection unit and back to the fluid flow line. The inlet flow is used to pressurize the storage tank and provide a solution to mix with injection solutions in the tank to provide an accurate preset or adjustable injection rate into the fluid flow line. Venproportioner ports provide an internal air release port and set injection ratios.

Abstract: A chemical delivery system having a body defining a main fluid flow passage through which a fluid passes and a storage tank for holding a chemical. An inlet nozzle delivers a quantity of the fluid in the main fluid flow passage to the storage tank to be mixed with the chemical and an outlet nozzle return a quantity of the fluid mixed with the chemical from the storage tank to the main fluid flow passage. An adjustment dial having a plurality of orifices of varying diameter that are capable of being individually placed into relation with the inlet nozzle may be used to control the amount of fluid that enters the first inlet nozzle from the main fluid flow passage. Furthermore, an outlet nozzle trap in fluid communication with a vent port of the outlet nozzle may be placed in fluid communication with a fill control port of the inlet nozzle. The fill control port is used to direct fluid to the outlet nozzle trap to control venting of air from the storage tank to the main fluid flow passage via the vent port.

Abstract: A fluid injector made of pressure rated components that attach to a fluid flow line so that flow is transferred from the flow line, into the injection unit and back to the fluid flow line. The inlet flow is used to pressurize the storage tank and provide a solution to mix with injection solutions in the tank to provide an accurate preset or adjustable injection rate into the fluid flow line. Vent/proportioner ports provide back flow protection, prevent fluid from siphoning from the storage tank, provide an internal air release port and set injection ratios. A mixing control valve adjusts the injection ratios by mixing outgoing injection solutions with incoming fluid from the fluid flow line. Flexible bladders isolate one or more injection solutions within one storage container which are injected simultaneously at independent injection rates.
