In order to prevent contact failure caused by the flow gauge used in sedimentation with conventional oil, the foreign matter is mixed in the flow sensor by the sealing structure which is installed in the tank and operated according to the float movement according to the flow rate. In order to provide a float type flow gauge with improved reliability of the flow sensor which can prevent the flow, the float type flow rate is composed of a float mounted in the oil tank, which is buoyant according to the oil level, and a flow sensor which is operated according to the movement of the float. In the sensor, the wave and the mover are in contact or non-contact with each other. The flow sensor main body with the rotary displacement measuring means for measuring the displacement according to the movement of the mover is formed in a sealed type, and the float arm with float is installed on the outer surface of the flow sensor main body so as to be free to swing. It is installed on the same rotation center line as the rotation center of the rotary displacement measuring means, and the magnetic force sensitive member in any one of the end of the float arm located on the flow sensor body side and the movable member provided in the rotary displacement measuring means. It is fixedly installed, and at the other place, the magnetic member is installed at the position corresponding to the magnetic sensitive member, so that it can be simultaneously moved by the mutual magnetic force during the swinging movement of the float arm, which has the effect of reliability in measuring the flow rate, and long life and high reliability. It is to be maintained.
