    Flow Meters

    A flow meter is a measuring device that is used to measure the volume or mass of a gas or liquid. ATO.com offers you various flow meters including magnetic flow meters, vortex flow meters, turbine flow meters, portable ultrasonic flow meters and small gas mass flow meters.

    • The magnetic flow meter or electromagnetic meter for all conductive liquids has measuring pipe size range of DN15, DN20, DN25, DN32, DN50, DN100, DN125, DN150, DN200 for choice.
    • The vortex flow meter is applicable pipe size from DN15 to DN300, suitable for liquids, gases and steam.
    • The turbine flow meter can be used for liquid flow measurement such as water and oil in the pipe size from DN4 to DN200 mm.
    • Portable clamp-on ultrasonic flow meter has a wide  measuring range of DN300-DN6000 with different size of transeducers - small/medium/large.
    • Digital gas flow meter for air/oxygen/nitrogen has selectable flow range 0~10L/min (DN 6mm), 0~25L/min (DN 6mm) and 0~200L/min (DN 12mm). The small one is also available, designed for low gas flow rate in the gas lines of 3mm and 8mm in diameter.
