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 13):
A drilling system for drilling a borehole with drilling fluid, the system comprising:\n a flow loop communicating the drilling fluid from the borehole to at least one drilling choke, communicating the drilling fluid from at least one tank to at least one pump, and communicating the drilling fluid from the at least one pump to the borehole; a differential pressure device disposed in the flow loop at a measurement location and producing a pressure drop in flow of the drilling fluid from an upstream side of the differential pressure device to a downstream side of the differential pressure device; piping diverting a portion of the flow in the flow loop at the measurement location from an inlet on the upstream side of the pressure device to an outlet on the downstream side of the pressure device; a flowmeter in fluid communication with the piping and measuring a parameter of the diverted portion of the flow; and a processing unit receiving the measured parameter from the flowmeter, the processing unit determining a diverted flow rate of the diverted portion of the flow from the measured parameter and correlating the determined diverted flow rate to a value of the main flow rate through the flow loop at the measurement location.
