A downhole tool used to measure the rate-of-flow and sometimes direction-of flow of borehole fluids. Usually these tools utilize impellers. During use the tools are run continuously with or against the direction of fluid flow. Sometimes the flowmeter measurements are made at stationary levels when fluid is diverted past the impeller blades by an inflatable packer. See also continuous flowmeter, fullbore-spinner flowmeter, packer flowmeter, spinner survey, and radioactive-tracer log.
a downhole tool used for monitoring, measuring or recording the rate of flow, pressure or discharge of liquids or gases mainly used in process industries such as food, chemical, refineries etc
an instrument used to measure linear, nonlinear, mass or volumetric flow rate of a liquid or a gas
an instrument used to measure, monitor, or record the rate of flow of liquids or gasses
Measures the vertical movement of fluid in a borehole.
A device used for measuring the flow or quantity of a moving fluid.
A logging device designed to measure the rate, and usually the direction, of fluid movement in a well; most are designed to measure vertical flow.
A device for measuring the rate of fluid flow, usually in pipes.
