Rosemount 3051S digital DP level system

Emerson Process Management has released a digital DP level system, the Rosemount 3051S Electronic Remote Sensor System. With over 10 patents, the 3051S ERS System is claimed to be a breakthrough technology that replaces mechanical impulse piping with two 3051S pressure sensors linked together electronically. Differential pressure is calculated in one of the two sensors and is transmitted using a standard two-wire 4-20 mA HART signal.

Suitable applications for the 3051S ERS System include tall vessels, distillation towers and other installations that traditionally have required excessive lengths of impulse piping or capillary. When used in these types of applications, the 3051S ERS System can deliver improved performance by replacing mechanical components with a digital architecture, resulting in faster response time and a more stable and repeatable measurement.

Installation and maintenance are also simplified. For example, cold weather installations often require heat tracing or insulation, and impulse lines need to be checked for leaks, condensation, evaporation and plugging. The digital architecture of the 3051S ERS System eliminates these practices, resulting in cleaner installations with less maintenance and upkeep.

The 3051S ERS System is also a multivariable solution that provides additional process information for more optimised control. In addition to the DP calculation, the 3051S ERS provides real-time access to the readings from each pressure sensor and a scaled output for tank level or volume measurement.
