Abstract
A system including an instrumented sub for supporting subterranean operations, the instrumented sub can include an upper and lower portion with a flow passage extending therethrough, and a valve that selectively permits or restricts fluid flow through the flow passage, and a rotary interface coupled to the upper portion and including a rotary portion and a stationary portion, where the rotary portion is rotationally fixed to the upper portion and rotates with the upper portion, where the stationary portion is rotationally coupled to the rotary portion, and where the rotary interface transfers communication signals between the stationary portion and the rotary portion to transmit commands or data to or receive the commands or data from one or more components of the instrumented sub. Can also include a method of using the instrumented sub to determine a vertical position or movement of a top drive.
