A multi-port injection system for injecting fluid into a plurality of fluid injection ports during a plurality of fluid injection cycles. The system provides highly accurate measurement of the volume of fluid injected into each injection port during each fluid injection cycle. The system generally includes a fluid holding tank, measuring tubes, a pump, a plurality of port valves coupled to the fluid injection ports, a fluid return valve, volume sensors, and a control unit. During a fluid injection cycle the control unit causes a portion of fluid to be pumped from a measuring tube to a port valve. After each fluid injection cycle, the control unit causes the fluid return valve to return the portion of fluid that was not injected to the measuring tube before the volume of fluid injected is measured.

Multi-port injection system

A continuous fluid metering system for continuously dispensing a fluid for injection and for accurately measuring the fluid dispensed. The system generally includes one or more fill valves for transferring fluid from an additive tank to first and second measuring tubes, one or more injection valves for directing fluid dispensed by the measuring tubes to an injection point such as an oil well, a pump, and first and second sensors that indicate the volume of fluid dispensed by the first and second measuring tubes as it is dispensed. The system also includes a control unit that controls the injection and fill valves to cause the fluid dispensed from the first and second measuring tubes to be alternately and continuously and directed to the injection point, and the first and second measuring tubes to be alternately and repeatedly refilled without substantial interrupting the flow of fluid to the injection point.

Continuous fluid metering system

A fluid metering system for accurately measuring and dosing one or more fluids. The fluid metering system generally includes a closed loop feedback system that monitors the volume of liquid chemical input into a system over a period of time. Based on the measured amount of chemical input into a system over a period of time, the system calculates whether or not an adjustment is required for the next input of chemical. The various embodiments utilize a measuring tube that is filled with a liquid chemical. A pressure sensor measures the pressure of the chemical in the measuring tube when filled and after emptied to calculate the total volume of chemical input into the system.
