  • 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? […]

    Biosphere 2 studies the impacts of drought on tropical rainforests using flow measurement

    Biosphere 2 studies the impacts of drought on tropical rainforests using flow measurement As the Earth’s climate changes, scientists expect that a hotter, drier world will have severe impacts on global ecosystems, with many areas subjected to increased water stress and/or drought. However, it is difficult to forecast the specific impacts climate change will have […]

  • Calibrating in-field PM air samplers with the FP-25

    Calibrating in-field PM air samplers with the FP-25 Flow measurement is critical to air monitoring processes, and quality data requires consistent airflow with minimal fluctuations. This is easy to achieve inside a lab where temperature, air pressure, and humidity are all carefully controlled. Of course, most environmental air monitoring takes place outside, where the instruments […]
