The present invention relates to an electromagnetic flow meter, comprising: a coil applied with power to form a magnetic field; an electrode measuring an electromotive force generated in accordance with a rate of flow passing through the magnetic field; an amplification circuit unit amplifying the electromotive force measured in the electrode; and a relay unit installed between the electrode and the amplification circuit unit to be turned on or off. As such, the flow meter is able to be protected from noise generated in the outside.

    본 발명은 전자 유량계에 관한 것으로, 전원이 인가되어 자계를 형성하는 코일; 상기 자계를 통과하는 유량에 따라 생성되는 기전력을 측정하는 전극; 상기 전극에서 측정된 기전력을 증폭하는 증폭회로부; 및 상기 전극과 상기 증폭회로부에 사이에 설치되어 ON 또는 OFF되는 릴레이부;를 포함하여 구성됨으로써, 외부에서 발생되는 노이즈로부터 유량계를 보호할 수 있도록 하는 효과가 있다.
