The Digital Vortex Flow meter that brought forth by us is suitable to be utilized for air, nitrogen,oxygen, coal gas, chemical gas, natural gas, and so on. Such flow meter can be used as flow transmitter in automatic control system. This type of instrument adopted advanced differential techninue, together with measurement of shielding, filtering, and isolating. The proposed product has better anti-vibration performance as well as signal stability. The Digital Vortex Flow meter is available in size of DN 10 to DN1000.
