  • Get full value from partial stroking

    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.

  • Sample pump eliminates emissions

    A compact system significantly improves analyzer accuracy. This innovative turnkey solution for analyzer emissions is a solid-state pump with an ultra-sensitive pressure regulator that mixes a compatible gas with the analyzer samples to achieve a constant vent header pressure — even during times of plant upset.

  • Compelling reasons to choose an insertion magnetic flow sensor

    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.

  • Can you trust your data?

    To make sense of supply chain data requires consolidating the information into a central repository and then using tools or applications to pinpoint errors and inconsistencies. It also includes taking possible corrective actions that enhance overall quality and confidence in the raw information.

  • Make your portable mixer work for you

    Understanding the fundamentals of fluid agitation can help meet the customer’s requirement and the processor’s need for efficiency. While portable mixers have been around for years, they often aren’t used to their full potential. Knowing the basics of mixing and flow patterns can help you get more out of your mixer.

  • How hydraulic modeling can improve the efficiency of your pump systems

    In spite of their large operating cost, most pump systems are inefficient by design. Among the common design problems are non-optimal pipe sizing, control valve utilization and, perhaps most common, incorrectly sized pumps. How a pump operates depends on the system, so improvements must focus on the system as a whole.
