Zusammenfassung:	A chemical/additive injection controller, system and method (i.e., utilities) are provided that control when an injection pump turns on and off in order to inject a predetermined volume of additives into a hydrocarbon production conduit over a predetermined number of cycles per day. The controller determines when to activate and deactivate (i.e., turn on and turn off) an injection pump to provide a desired total additive injection volume over an injection period (e.g. 24 hours). More specifically, the utilities incorporate a flow meter that monitors the actual amount of additive that is injected during a pump cycle. Once an injected volume meets or exceeds a target injection volume the pump is deactivated. The flow meter continues to monitor the injection volume including amounts injected after power to the pump is deactivated to provide an accurate measure of the total injection. Subsequent injections are varied based on the actual measured volume of one or more previous injections.
