In water and wastewater applications, corrosive substances or blockages from sludge or slurries can compromise your pressure and temperature instruments. How can you safeguard these instruments and maintain operational efficiency? A diaphragm seal offers protection, but not just any seal will suffice. You'll want a diaphragm seal with a flushing connection that can simplify the seal's cleaning process and prevent clogging. I've been working with Ashcroft - a leader in pressure and temperature instrumentation - for the better part of 33 years. Initially, I was the branch manager at an Ashcroft distributor, and for the past 10 years, I have been the Northwest territory manager. In both roles, I have helped customers understand the features and benefits of water and wastewater instrumentation. Read this article to learn what a flushing connection is, how it can help a diaphragm seal be more effective in harsh applications and when it's most advantageous to put one to work for you.

Working in the oil and gas or chemical industries means your process and your people are exposed to dangerous acids and chemicals. Chemicals such as hydrofluoric acid and others can create dangerous conditions and corrode certain materials, which could result in hazardous leaks. That's why it is imperative to select pressure and temperature instrumentation that can safeguard your entire operation from the potentially damaging effects of these applications. While dangerous acids have been safely used in industrial applications for many years, specifying proper pressure instrumentation with the appropriate wetted materials for these locations, requires unique expertise. That's where Ashcroft can help. With decades of experience in pressure and temperature instrumentation for the process industry, we have guided customers to the information they need to ensure they are choosing the safest instrumentation for their acid application. This article will discuss the safety concerns for harsh acid applications and what types of pressure instruments can best handle these challenging working environments.
