The float of a metal tube float flow meter is equipped with a guide rod, allowing the float to move up and down smoothly along this rod, thereby reducing its oscillation. However, if the guide rod bends or the float is slightly deformed, its movement will be restricted and the readings will become inaccurate. The most likely reason is the rapid opening or closing of the valve, which causes cavitation or water hammer effects; this leads to violent impacts on the float inside the metal tube float flow meter, resulting in deformation of the float or bending of the guide rod. The solution is to operate the valves slowly when opening and closing them. The second reason is the impact caused by magnetic coupling. Prolonged exposure to high temperatures or extremely harsh operating conditions cause a decline in magnetic coupling and magnetism, preventing the movement of the float from driving the pointer to indicate. Another possibility is that the metal tube float flow meter has absorbed many iron powder-like impurity particles inside it. The solution is to use a magnetic filter in front of the metal tube float flow meter to filter out impurities such as iron shavings and iron powder. The third reason is caused by the deformation of the internal structure of the metal tube float flowmeter. Possible reasons include jamming of mechanical transmission components such as pointer gears, or deformation of the PTFE float or lining. In this case, only by replacing the float and liner can the problem be solved. Furthermore, because the medium is too viscous and sticks to the float and inner walls, it not only causes errors in the flow meter but also leads to poor operation of the pointer in metal tube float flow meters. In this case, the flow meter simply needs to be removed and cleaned to restore its original accuracy. For more information, please visit the company’s official website at http://www.yb1518.com/.
