Metal tube float flowmeter

A metal tube float flowmeter comprises a tube body, an outlet flange and an inlet flange are arranged at the upper end and the lower end of the tube body respectively, an indicator is arranged on the side wall of the tube body, a floater is arranged in the tube body, the upper end and the lower end of the floater are connected with connecting rods respectively, and the other ends of the two connecting rods are connected with damping devices respectively. The damping device is installed in the pipe body through a supporting rod, a flow divider is detachably connected into the inlet flange, and a filter screen is arranged between the damping device at the lower end and the floater. The metal tube float flowmeter is simple in structure, convenient and fast to use and accurate in measurement, impact of sundries on the float is reduced by arranging the filter screen, and corrosion resistance of the float can be well improved by galvanizing the outer surface of the float, so that the effect of prolonging the servic
