An embodiment a monitoring and control system that includes an instrumented top sub configured to obtain drilling data.

Monitoring system with an instrumented surface top sub

A flow monitoring system for monitoring fluid flow. The flow monitoring system including a conduit, a first transducer, a second transducer, and a flow diverter. The conduit has an inner surface that defines a flow channel extending through the conduit. The conduit defines a bore extending from the inner surface to an outer surface. The first transducer is positioned within the bore of the conduit, such that at least a portion of the first transducer extends into the flow channel. The second transducer is positioned such that the second transducer can send and receive signals propagating through at least a portion of the flow channel to and from the first transducer. The flow diverter is positioned within the flow channel of the conduit adjacent to the first transducer and the second transducer.

System and method for monitoring mud flow in a component of drilling system

A strain sensor assembly is configured to detect one or more of forces applied to a structure having a recess. The strain sensor can include at least a pair of opposed strain gauge members that extend from the support member. Each strain gauge member defines a support portion carried by the support member and a biasing portion. The support portion includes at least one strain gauge sensor. The biasing portion is configured to bias against a wall of the recess of the structure when the strain sensor assembly is disposed in the recess. The strain sensor assembly is configured such that the at least a pair of strain gauge members form an interference fit with the wall of the recess when the strain sensor assembly is inserted in the recess.
