ABSTRACT:
A chemical injection system for automatically injecting chemicals into a fluid process line in direct proportion to the fluid flow. A fluid flow meter in the line operates a cam which in turn operates an air valve for pneumatically actuating a controller by air pulses. The controller in turn supplies pressurized air to an injector pump to operate the pump in cycles corresponding to the air pulses. By manipulating valves the controller can be changed from operating in response to the fluid-flow related air pulses regulated by the meter to a self-contained adjustable speed of operation and such valves may be remotely controlled.
