Systems and Related Methods For Installing Or Replacing A Process Measurement Instrument

摘要

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.

1. A method for replacing a process measurement instrument comprising:
operating a process under pressure; providing a first measurement instrument mounted with respect to a measuring assembly positioned for measuring a parameter associated with the process; removing the first measurement instrument from the measuring assembly while the process operates under pressure; replacing the first measurement instrument with a second measurement instrument while the process operates under pressure by installing and mounting the second measurement instrument with respect to the measuring assembly; wherein the first measurement instrument includes a first coupling that allows a user to remove the first measurement instrument from the measuring assembly while the process operates under pressure without substantial loss of fill or sensing media from the first measurement instrument; wherein the second measurement instrument includes a second coupling that allows the user to replace the first measurement instrument by mounting the second measurement instrument with respect to the measuring assembly while the process operates under pressure, the second measurement instrument: (i) containing pre-filled sensing media configured to react to pressure of the process, and (ii) pre-charged to a pre-determined pressure level.
