Close Coupling

A close-coupled solution is an instrument mounting system that enables a user to connect an instrument directly on to the process line, and primary isolation valve. The overriding objective of this is to optimize the accuracy of measurement, by eliminating the long runs of tubing, bends and joints between process pipe and instrument that can cause pressure drops, and gauge/ impulse line errors.

Close-coupled innovations for mounting pressure instrumentation can deliver enormous advantages to both instrument and piping engineers, ranging from significantly enhanced measurement accuracy, to simpler installation and reduced maintenance.

Parker has created a comprehensive range of manifold mounting solutions for the main types of pressure instrumentation, employing close-coupling techniques which eliminate impulse lines and connections to improve overall instrument performance and reliability.

A good example of where a close-coupled solution can deliver huge advantages is with transmitter hook-ups. These are often configured individually for each application, and can be large, heavy and difficult to install. By replacing such arrangements with purpose-designed close-coupled manifold/mounting solutions, users are able to optimize accuracy and reap a whole range of additional benefits
