LIMECO EZ® Nitrogen Loading System
Liquid Meter Company is proud to introduce the new "EZ" Nitrogen Loading System that is designed to increase the performance of pipeline surge relief valves. Currently the industry standard for gas loaded surge relief valves is to place a supply of nitrogen next to the valve and use a mechanical regulator to maintain the system relief set point. However, when practiced in the field, the mechanical regulator is extremely inconsistent. With thermal gains and losses in pressurized nitrogen, the relief set point is all over the map with a common surge relief range of +/- 30 PSI. Our system is designed to accurately control the nitrogen set point in the surge relief valve to a range of +/- 3 PSI. The "EZ" maintains that accuracy though out the changes in the environment, while at the same time reducing the need for service calls and maintenance. This Division 1, Class 1 system is designed for the petroleum industry to use for surge relief as well as pressure testing/certifying pipelines. We currently have a demo unit that can be brought to your facility for custom testing and observation.
