  • 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 […]
