Abstract
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.
Claims20
A fluid metering system for chemically treating an oil well, comprising:
- a first additive tank storing a first fluid;
- a first measuring tube fluidly connected to the first additive tank;
- a first fill valve fluidly connected between the first additive tank and the first measuring tube;
- a first fluid pump, wherein an inlet of the first fluid pump is fluidly connected to the first measuring tube and wherein an outlet of the first fluid pump is fluidly connected to an oil well;
- and
- a control unit in communication with the first fill valve and the first fluid pump, wherein the control unit controls a state of the first fill valve and the first fluid pump for a fill process and for a dosage process, wherein the control unit opens the first fill valve and deactivates the first fluid pump during the fill process thereby filling the first measuring tube with the first fluid, and wherein the control unit closes the first fill valve and activates the first fluid pump during the dosage process thereby transferring the first fluid from the first measuring tube to the oil well for treating the oil well.

- a first fill valve fluidly connected between the first additive tank and the first measuring tube;
- a first fluid pump, wherein an inlet of the first fluid pump is fluidly connected to the first measuring tube and wherein an outlet of the first fluid pump is fluidly connected to a pipeline, wherein the pipeline is a water pipeline or a gas pipeline fluidly connected to a separator of an oil well;
- and
- a control unit in communication with the first fill valve and the first fluid pump, wherein the control unit controls a state of the first fill valve and the first fluid pump for a fill process and for a dosage process, wherein the control unit opens the first fill valve and deactivates the first fluid pump during the fill process thereby filling the first measuring tube with the first fluid, and wherein the control unit closes the first fill valve and activates the first fluid pump during the dosage process thereby transferring the first fluid from the first measuring tube to the pipeline for treating the fluid within the pipeline.
