In a recent edition of Chemical Engineering, the editors brought together experts on liquid analysis to discuss how advanced digital measurement technology is making liquid analysis smarter, easier to use, more cost effective and adaptable to demanding applications. Included in the lineup of experts was Jason Dalebroux, director of product management for Rosemount liquid and combustion analysis with Emerson.
Jason says, “Any time you have an extreme application — those with high temperatures, high pressures or dirty conditions — better measurement methods are required. There are several solutions available on the market today to address more difficult process conditions and prolong sensor life.”
Jason goes on to explain that most manufacturers offer re-buildable sensors so users can cost-effectively change the electrolytes and recharge pH sensors used in higher temperatures, as well as sensors built with more resistant materials so sensors operate longer without clogging in high suspended-solids environments.
“We are also seeing new types of instruments, such as optical-based technologies, for measuring concentrations and substances within a liquid,” says Dalebroux.
One of the advanced technologies featured in the article is the Rosemount Analytical RDO optical dissolved oxygen sensor and analyzer. Optical technology makes the sensor more resistant to fouling than polarographic sensors, an important advantage in wastewater where coating is a common problem.
