    What is mass flow?

    What is mass flow? A common way to measure and control flow is with a mass flow instrument, but what is mass flow? The answer to this can be approached from a number of angles, which we cover in this article. What do mass flow meters and controllers do? Most mass flow devices output a […]

  • 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? […]

  • Bleeding your liquid device tutorial

    Bleeding your liquid device tutorial Alicat differential pressure based liquid flow meters and controllers should only be used to flow liquids. Sometimes, however, a liquid contains trapped air or gas bubbles. It is critical that the device only measures the pressure of the gas-free liquid flowing through the device (no bubbles), or readings will be […]

  • Measuring vent and greenhouse gas emissions

    Portable gas flow meters are use multiple flow sensors to capture pressure, temperature, and flow data quickly at the source.

  • Correcting flow data after choosing the wrong gas in Gas Select

    Correcting flow data after choosing the wrong gas in Gas Select Correcting flow data after choosing the wrong gas is fairly straightforward. As both the mass flow rate and volumetric flow rate depend on gas viscosity, having the wrong gas selected leads to readings that are approximately off by the ratio of the viscosities. This […]
