Pressure Measurement & Control
Available in Traditional and Compact options, the rings provide a process-to-seal connection and allow for faster diaphragm seal maintenance without disconnecting them from process flanges.
Both versions come pre-assembled, including the flushing ring, matching valves and connections, allowing technicians to commission devices faster by eliminating the need to procure and assemble components onsite. They are factory leak-tested so users can mount products to vessels right out of the box. When installed, diaphragm seal maintenance is significantly faster without compromising safety, while reducing stocked inventory and management of multiple vendor piece-parts.
Version-specific features include the following:
• The Rosemount 319 Traditional flushing ring design utilises a flow-through cleaning action, and can be sized to fit almost any application. Configurations are offered with a choice of ball valves, needle valves or gate valves, and in multiple materials, flange types, sizes and ratings.
• The Rosemount 319 Compact flushing ring design removes residual buildup quickly, cleaning five times faster over 30% more surface area and with 50% fewer leak points than other flushing rings. Assemblies accommodate a wider range of applications due to their smaller footprint, for accurate differential pressure measurement in applications that have limited space for flushing ring installation. Configurations are offered with needle valves, and in multiple materials, flange types, sizes and ratings.

Editor's Choice
This article gives an example of an important flow control system for flare gas in a petrochemical refinery. The control was suffering from serious problems, often cycling severely, and at other times the flow process variable (PV) would suddenly move quite a lot away from the setpoint (SP).

Editor's Choice IT in Manufacturing
As AI evolves, it is evident that the most powerful models will be cloud-based, and hosted in data centres that are beyond the control of the average business. The practical application of AI in manufacturing control and automation will only be possible if some of the computing workloads can be brought onto the plant, inside the firewall and inside the plant network.
