Traditional differential pressure (DP) technologies such as wet leg and dry leg systems, which utilize impulse piping and capillary-based solutions, are commonly used to measure tank level. However, advanced solutions have been developed to improve performance and address the application challenges that traditional configurations face. These innovations include the Rosemount 3051S Electronic Remote Sensor (ERS) System and Tuned-System Assemblies.
Impulse piping is often difficult to install and maintenance intensive. Rosemount ERS Systems replace mechanical impulse piping and long lengths of capillary with two pressure transmitters that are linked together electronically. This digital architecture improves time response and measurement accuracy. ERS Systems are best suited for distillation towers, tall vessels, and other applications with long spans or widely varying temperatures.
Tuned-System Assemblies are often preferred over Balanced Systems because they deliver reduced measurement error, increased response time, and decreased installation costs. The asymmetrical design of the Tuned-System Assembly minimizes fill-fluid volume on the high side in order to counteract the temperature induced density effects experienced by vertical installations. Tuned-System Assemblies are considered best practices for indoor applications, shorter spans, and tanks with high pressure vessels.
The Technical Note Rising to new levels with Rosemount 3051S Electronic Remote Sensor (ERS) Systems and Tuned-System Assemblies further illustrates how these two innovative technologies can improve performance and solve many of the traditional challenges encountered when making level measurements.
