The present disclosure provides improved process measurement assemblies and methods for replacing/installing devices/instruments (e.g., gauges, digital gauges, transducers, switches, etc.) associated with process measurement assemblies. More particularly, the present disclosure provides improved process measurement assemblies (e.g., diaphragm seal assemblies or isolation ring assemblies) having couplings (e.g., dry-break couplings) that allow a user to replace and/or install process measurement instruments/devices to and/or from the process measurement assemblies, and related methods of use. In general, the present disclosure provides for improved systems/methods for installing or replacing a process measurement instrument to and/or from process measurement assemblies (e.g., diaphragm seal assemblies or isolation ring assemblies). In exemplary embodiments, the present disclosure provides for a system/method for installing/replacing a process measurement instrument wherein the process operating under pressure is a flow stream process, the flow stream process having a solids content.
