  • Penn Electronic Design Shop uses mass flow control to optimize olfactometer for short-term memory retention research

    Penn Electronic Design Shop uses mass flow control to optimize olfactometer for short-term memory retention research Advances in science have resulted in a much deeper understanding of the most complex organ in the human body: the brain. One remaining mystery is the mechanism by which a human brain retains and recalls information. The Gottfried lab […]

  • UPB tests hydrogen-diesel engine efficiency using mass flow meters

    UPB tests hydrogen-diesel engine efficiency using mass flow meters In an effort to reduce carbon emissions from the transportation sector, the European Commission is working to reduce CO2 emissions from transportation by 37.5% over the next 10 years. A promising approach is to focus on developing alternative fuels and technologies to replace greenhouse intensive ones. […]

  • What type of fluid can I flow through my Alicat flow instrument?

    What type of fluid can I flow through my Alicat flow instrument? Alicat devices can be customized to flow a wide range of fluids, however each device has its own unique capabilities. Taking a look at gas flow vs. liquid flow devices can help you get the most out of your instruments while minimizing risk […]

  • What is mass flow?

    What is mass flow? Most Alicat devices measure and control the mass flow rate of a gas. As gas flows through an Alicat, it passes through a flow channel with temperature and pressure sensors. These sensors measure the instantaneous temperature and pressure of the gas stream, and use that information in combination with known gas […]

  • What is the difference between mass flow and volumetric flow?

    What is the difference between mass flow and volumetric flow? Understanding the difference between mass flow and volumetric flow is important when determining which flow instrument is right for your application. Here we introduce the concepts of mass flow and volumetric flow and discuss use cases for each measurement. What is a volumetric flow rate? […]

    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 […]

    High accuracy, low-flow color dosing with Coriolis mass flow meters

    High accuracy, low-flow color dosing with Coriolis mass flow meters Many liquid laundry detergents are easily recognized by their distinct blue color. The addition of such blue coloring and other fluorescing agents adds trace amounts of dye to fabrics, both counteracting discoloration and improving brightness. Challenge: Inaccurate, inefficient pumps lead to noticeable variation Modern blue […]

  • Framergy purifies methane from natural gas streams using MOFs and Coriolis mass flow meters

    Framergy purifies methane from natural gas streams using MOFs and Coriolis mass flow meters Metal organic frameworks (MOFs) are a novel class of nanomaterials which are highly effective as a solid adsorbent and utilize their unique “cage-like” structure to trap molecules. Because of these properties, MOFs have been studied for numerous fluid storage, separation, and […]

  • 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 […]
