Abstract
An in-line flowmeter for large diameter pipes includes an outer pipe with a diameter equal to that of the pipe to which it is coupled and an inner measuring tube carrying a portion of the flow, the flow through the measuring tube being sensed by a flowmeter associated with the measuring tube and with the total combined flow rate out of the in-line flowmeter calculated from the sensed flow through the measuring tube.
Claims23
A flowmeter for measuring flow in a pipeline without constricting the flow in the pipeline to permit measuring of flow in the pipeline, comprising:
- an exterior tube having a diameter commensurate with the diameter of the pipeline;
- an interior measuring tube placed within said exterior tube, said interior tube including a sensor for measuring the flow through said interior tube;
- and
- a processor coupled to said sensor for calculating the combined flow through said interior measuring tube and said exterior tube based on sensed flow in said interior measuring tube, whereby the total flow in said pipeline is measurable without constricting the flow in the pipeline during the measurement process.
