How can such a little gauge play such a BIG role in process safety? It is actually quite simple, yet so many relief system designs fail to incorporate them.

In this article, I will explain what a “tell-tale” gauge is and what purpose it serves, as well as document their mandate for those relief systems that utilize dual in-line relief systems.
