  • Characterization of Coriolis measurement technology

    Characterization of Coriolis measurement technology Coriolis technology can flow fluids ranging from only hundredths of a gram per hour up to several million kilograms per hour. On the low end, a Coriolis device may be so small that it can fit in the palm of your hand. At higher flows, they may be as large […]

  • Overcoming pump limitations with a Coriolis meter-pump system

    Overcoming pump limitations with a Coriolis meter-pump system In non-pressurized systems, various types of pumps can be used to induce liquid movement or flow. However, many of these pumps have limitations in both batch and continuous processes. Gravity pumps must be located below the fluid source and are typically not automated, limiting process configurability and […]

  • Active flow control with pressure control and a Coriolis mass flow meter

    Active flow control with pressure control and a Coriolis mass flow meter In processes operating at extreme conditions, it can be a bit tricky to maintain reliable flow control. The combination of a Coriolis mass flow meter, dual valve pressure controller (PCD), and dome loaded back pressure regulator (BPR) enables automated flow control under the […]

    Addressing scaling challenges of bioreactor sparging using mass flow control

    Addressing scaling challenges of bioreactor sparging using mass flow control This article was originally published in Fluid Handling Pro on June 29, 2021. Read the original article here. Bioreactor sparging systems are designed to introduce oxygen to feed cell cultures, while removing carbon dioxide to prevent toxic buildup. Various bioreactor features and components are critical to […]

  • Alicat mass flow controllers resist back pressure contamination

    Evaluation of Alicat Mass Flow Controllers’ Resistance to Back Pressure Contamination Mic Chaudoir, Ph.D. Rohan Morajkar, Ph.D. Introduction Mass flow controllers (MFCs) are essential to many modern production and test processes. Precise and reliable flow control is particularly important for efficient, sustainable production in applications such as glass fabrication and bioprocessing. Within such processes, MFCs […]

  • Turbulent non-Newtonian liquid flow
    Flowing non-Newtonian fluids

    Flowing non-Newtonian fluids Finding the right instrument to measure or control non-Newtonian fluids can be a challenge. Some popular flow technologies like electromagnetic meters can exhibit up to a 20% deviation in accuracy when used for such fluids. Ultrasonic flow meters have also shown up to 15% deviation when used for non-Newtonian fluids transitioning between […]

    Hydrogen fuel cell regulation and testing solutions

    Hydrogen fuel cell regulation and testing solutions Hydrogen fuel cells are a clean, environmentally friendly alternative to traditional combustion processes. While they show tremendous promise, fuel cell regulation is critical to achieve the process efficiency required for them to become truly viable as an alternative energy source. Precise and adaptive regulation of system pressures and […]

    Optimizing supercritical CO2 solid-liquid extraction with Coriolis mass flow

    Optimizing supercritical CO2 solid-liquid extraction with Coriolis mass flow CO2 is used in all kinds of industrial applications; for example, liquid CO2 is commonly used as a cooling agent and solid CO2 (dry ice) as a dairy preservative. Here, we focus on the industrial applications of supercritical CO2 (sCO2). What is sCO2? A supercritical fluid […]

  • Porous chocolate, which is aerated for creaminess
    Aerating chocolate using mass flow control

    Aerating chocolate using mass flow control Aerated chocolate is increasingly popular because of its particular mouthfeel: bubbles in the chocolate make it lighter, with a unique texture. An aerated chocolate bar has more surface area than a standard chocolate bar, which is why it melts faster in your mouth, intensifying its taste. How are bubbles […]

    Brewing with Alicat: Controlling carbon dioxide sparging

    Brewing with Alicat: Controlling carbon dioxide sparging Beer is the beverage of choice for billions of people around the world. Whether ale, lager, or stout, carbon dioxide sparging is the process by which beer gets carbonated – making it the not-so-subtle difference between a refreshing pint and a flat disappointment. The average beer drinker is […]
