    How we use your application info to build a custom device

    How we use your application info to build a custom device Alicat mass flow and pressure controllers and meters are custom built to meet specific application needs. Some of the most common considerations when building a custom Alicat solution include: Application Flow rate Fluid type Inlet and outlet pressures Process temperature Analog/digital communication Process threads […]

  • 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? […]

    More efficient flow control for bioreactors and bioprocess systems Mic Chaudoir, Ph.D. Chip Stacy, AbbVie Senior Engineer of Digital Systems As the need for potent and specific pharmaceuticals grows, pharmaceutical manufacturers have turned to biologics to meet the increasing needs and find treatments for complex and currently untreatable conditions including cancer and myriad genetic diseases. Biologics […]

  • Operating principle: Coriolis mass flow technology

    Operating principle: Coriolis mass flow technology Alicat’s CODA-Series of mass flow meters and controllers utilizes the Coriolis operating principle and uses the single tube setup described above. The measurement process is demonstrated in this video: The Coriolis effect is commonly used to explain why hurricanes, tornadoes, and typhoons spin clockwise in the Southern Hemisphere and […]

  • How tough is an Alicat?

    Many processes require corrosive gases like ammonia or sulfur dioxide that cause damage to the instrument. These Alicats are built to withstand tough process conditions; configured to thrive in harsh ambient conditions.

  • Understanding Alicat calibration and accuracy specifications

    Understanding Alicat calibration and accuracy specifications Each device that goes through an Alicat calibration comes with a NIST-traceable Certificate of Calibration. This guarantees that the device’s calibration can be traced back to primary SI standards such as mass and pressure. As a result, an Alicat device will output mass flow rates that fall within the […]
