    What is a flowmeter?Flowmeters are used to measure the mass flow rate or the volumetric flow rate of a fluid in many types of applications. The type of airflow meter is based on its application. Volumetric flow rate and mass flow rate are units used to measure gases and liquids. Both volumetric mass rates are related to the density of the fluid.
    What is a mass flow meter?A mass flow meter, also known as an inertial flow meter, is a device that measures mass flow rate of a fluid traveling through a tube. The mass flow rate is the mass of the fluid traveling past a fixed point per unit time.

    What type of flow meter is used for gas flow?Thermal dispersion flow meters are commonly used for general industrial gas flow applications in pipes and ducts, whereas capillary types are primarily used for smaller flows of clean gases or liquids in tubes. This type is most widely used for thermal mass flow meters in industry.
