Level Measurement & Control


Endress+Hauser prevents storage tank overfill

September 2013 Level Measurement & Control

Storage tanks in the oil and gas industry are used to hold environmentally damaging liquids that can cause serious incidents, including personnel injuries, if not properly monitored. A faulty fuel gauge can fail to alert operators that fuel storage is reaching an alarmingly high level, which could cause large quantities of petrol to overflow. As a consequence, vapour clouds are formed leading to explosions or fires that can last for days. Overfill prevention systems are a must for obvious reasons, but they can be costly, tedious to implement and difficult to maintain if custom built.

A pre-configured solution package reducing commissioning time and maintenance costs,

Endress+Hauser’s solution reduces project costs by up to 20% and lowers implementation risk as it is based on a standard approach with repeatable designs that have been tested and documented. The system was developed together with Rockwell Automation and offers a complete and integrated solution able to address the entire safety loop, from measuring and monitoring to correcting elements. Devices are pre-integrated which means there is only a need for on-site parameter set up. The solution is also modular and thus easily extended.

Compliance with industry best practices, API 2350 and IEC 61511 standards, the solution delivers the following:

* Scalability to user needs.

* Suitability for manual and automated operated facilities.

* Up to SIL level 3.

* Display of detailed warning and alarm messages on both text display and operating panel.

* Fail-safe high warnings and alarms.

* Integrated automated proof-test procedure.

* Automatic recording of all events for transparency and traceability.

* UPS operation up to 30 minutes operation.
