Overfill Prevention Solutions in Action
Does the risk of a tank overfill worry you?
For a long time overfills have been a leading cause of serious incidents in the process and bulk liquid industries.
But overfills do not occur randomly. They are predictable and thereby preventable.
Emerson has the knowledge and expertise to provide a holistic view of tank overfill prevention and can guide you in selecting the right solution to come closer to the goal of zero tank overfills.

Conformance to the most recent globally recognized industry standards is critical for modern overfill prevention.
According to the globally accepted standards IEC 61511 and API 2350 (scope illustrated in figure), best practice is to use SIS/SIL devices certified to IEC 61508.
There are also numerous national and tank specific standards available for overfill prevention that may be applicable for individual facilities.

Selecting the right overfill prevention solution is not easy. There are a number of questions you need to ask.
- Do you need a continuous level device, or point detection?
- What is the media you are measuring?
- What kind of tank and how large is it?
- What are your proof-testing requirements?
- Do you need high accuracy measurements for custody transfer?
- What tank openings do you have and how many?
Emerson’s experts are here to help with these questions and to guide you to the best solution, no matter what your requirements are.
