The following is a brief analysis of some common faults related to the float: Common fault 1: Damage to the float, resulting in incorrect readings on the display panel. Fault analysis: The damage to the float in magnetic flap level gauges is usually caused by the following reasons: 1. The permanent magnets inside the float become loose, preventing the float from functioning properly. 2. If the float is used for an extended period of time or in high-temperature environments, demagnetization occurs, rendering it unusable. 3. Due to an inadequate strength design, the float sinks and collapses inward when subjected to excessive pressure. 4. The weld area is not fully welded or there are gaps in the welding, which causes the weld to crack under pressure applied to the float, allowing water to enter the float. Common fault 2: The float gets stuck, causing incorrect readings on the display panel. Fault analysis: The float in the magnetic flap level gauge is stuck. Common causes include the following: 1. The ambient temperature is too low, causing the medium to freeze and preventing the float from rising or falling. 2. The float is stuck by iron filings or other contaminants attracted to it due to its own magnetism. 3. After being used for a while, the float may get stuck by existing impurities and fail to move. 4. The installation angle of the float is less than 87 degrees; an inclined float affects the upward and downward movement of the buoy. To prevent the aforementioned failures, the floats of the magnetic flip-level gauge produced by Shenzhen Jiwei Automation Technology Co., Ltd. are made from high-quality 304 or 316L stainless steel. The inner diameter of the float and the outer diameter of the buoy are matched precisely, and the size of the buoy is calculated accurately based on the density and pressure of the medium present in the system. Stringent quality control is applied at every stage, from material selection to design and production, thereby reducing the likelihood of buoy-related failures and ensuring the stable operation and proper functioning of the magnetic flip-level switch. http://www.jiweimeter.com/uploads/image/20170503/1493798196.png Attachment: Working principle of the Flap-11 series magnetic flap level gauges. The Flap-11 series magnetic flap level gauges utilize the principles of communication vessels and magnetic coupling to enable real-time measurement and display of liquid levels. As the liquid level in the container rises or falls, the magnetic float inside the float barrel moves up or down as well; the permanent magnet within the float drives the magnetic flap outside the float barrel to rotate 180° through magnetic coupling. The two sides of the flap are coated with different colors (usually red and white) to indicate the level of the liquid. Generally, as the liquid level in the container rises, the flap changes from white to red; when the liquid level drops, it changes from red to white. The boundary between red and white on the indicator represents the actual height of the liquid level in the container. Depending on the chemical properties of the liquid, buoyants made of different materials can be selected to suit them ； Depending on the density of the liquid, floats of different volumes and weights are selected to match it, thereby achieving optimal measurement accuracy. The above is an introduction to the common faults of the float in magnetic flap level gauges and their solutions.
