Abstract:
In a drilling system for drilling a borehole with drilling fluid, a flow loop communicates the drilling fluid, and a differential pressure device in the flow loop at a measurement location produces a pressure drop in flow. The measurement location can be between the borehole and a drilling choke or between a mud pump and the borehole. Piping diverts a portion of the flow at the measurement location so a flowmeter can measure the diverted flow portion. A processing unit receives a measured parameter from the flowmeter and determines a diverted flow rate of the diverted portion therefrom to correlate it to a value of the main flow rate through the flow loop at the measurement location.

Claim (Index 16):
A method of measuring a main flow rate of flow through a flowline, the method comprising:\n producing, using a differential pressure device disposed in the flowline, a pressure drop in the flow from an upstream side of the differential pressure device to a downstream side of the differential pressure device; diverting, using piping on the flowline, a portion of the flow in the flowline from an inlet on the upstream side of the differential pressure device to an outlet on the downstream side of the differential pressure device; measuring, using a flowmeter in fluid communication with the piping, a parameter of the diverted portion of the flow; determining, using a processing device receiving the measured parameter, a diverted flow rate of the diverted portion of the flow from the measured parameter; and correlating, using the processing device, the determined diverted flow rate to a value of the main flow rate through the flowline.
