Abstract: The present disclosure introduces an apparatus including a toolstring for use in a tubular extending into a subterranean formation. The toolstring includes modular components that include one or more caliper modules and a power and control (P/C) module. The one or more caliper modules each include radially rotatable fingers for sensing an internal diameter of the tubular. The P/C module is operable for distributing power and control signals to the one or more caliper modules. The caliper and P/C modules are mechanically and electrically interconnected by common lower interfaces of the caliper and P/C modules.

Abstract: The present disclosure introduces an MFC module for use in a tubular extending into a subterranean formation. The MFC module includes a tool body having slots that each include a receptacle. The MFC module also includes measuring fingers each independently rotatable within a corresponding one of the slots via a corresponding pivot formed by complementary linking portions of the measuring finger and the receptacle of the corresponding slot. The linking portions of the receptacle are situated on opposing side walls of the receptacle. The MFC modules also includes linear displacement sensors each operable for sensing an orientation of a corresponding one of the measuring fingers relative to the tool body.
