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 IPDE 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.
Faster installation and maintenance
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, as detailed below:
Although every product is available with NPT threaded connections, Parker also offers each manifold with ‘A-LOK®’ compression-assembly end connections, to eliminate threads and any need for thread sealants – which can be a common cause of leakage in the field. In addition, all of our close-coupled solutions conform to the IPPC directive, so you can be sure that by reducing potential leak paths, your process is cleaner as well as safer, making the Parker offering an environmentally friendly choice.
