We are proposing the best-in-grade Vortex Air Flow Meter, which is ideal to be utilized for natural gas, coal gas, chemcial gas, nitrogen, oxygen, air and a lot more. As flow transmitter, this type of flow meter can be used in automatic control system. Moreover, the presented product adopted ultra-modern differential technique, along with measurement of filtering, isolating, and shielding. Moreover, it possesses better anti-vibration performance and signal stability. The Vortex Air Flow Meter is availale in size of DN 10 to DN1000.
