The Signet 2551 Magmeter is an insertion style magnetic flow sensor that features no moving parts. The sensor design is available in corrosion-resistant materials to provide long-term reliability with minimal maintenance costs.
In this installment of Ask The Experts, noted process control authority and CONTROL Columnist Béla Lipták and his cadre of automation experts answer a readers question regarding control valves for slurry services.
There are two main drivers for partial stroking of valves in safety systems: the desire to extend manual test intervals to as long as possible; and to reduce the amount of redundant hardware required for higher safety integrity levels. Like most things in life, it all boils down to one thing: trying to save money.
Measuring flow rates and volumes of water and chemicals in the water, wastewater and chemical treatment industries requires the latest, simple to use and cost-effective technology that can keep up with the rigorous demands of the various applications.
Understanding the fundamentals of fluid agitation can help meet the customers requirement and the processors need for efficiency. While portable mixers have been around for years, they often arent used to their full potential. Knowing the basics of mixing and flow patterns can help you get more out of your mixer.

To make the most of diagnostic equipment used in chemical processing, technicians must stretch their knowledge of control valves and related diagnostic equipment that keeps tabs on valve health and safety.
Control's Béla Lipták continues his series on control of distillation processes, this time focusing on managing reboiler flow, temperature, feed rate, loading and reflux for economy, stability and safety.
Valves and actuators designed for handling radioactive waste must meet strict government requirements. This sometimes requires unconventional solutions. Such was the case at the Hanford Waste Treatment Project (WTP), Hanford, Wash.
