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.
