  • 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 […]

    How it works: High-accuracy multi-gas calibrations (Gas Select)

    How it works: High-accuracy multi-gas calibrations (Gas Select) Alicat mass flow meters and controllers can measure or control over 98 gases with NIST-traceable accuracy. In this article, we discuss how an Alicat maintains high accuracy measurements across this wide range of gases. Alicat devices are pre-loaded with 3-dimensional gas properties data Alicat mass flow instruments […]
