A magnetic flap level gauge operates by measuring a float inside the chamber, utilizing the principle of buoyancy. During the installation and calibration of such gauges, it sometimes happens that the actual liquid level in the tank rises, but the reading indicated by the gauge does not reflect this increase. Further inspection by closing the valve revealed that the float was always in a descending position; this article analyzes the specific causes of this fault phenomenon. One scenario is that the magnetic float in a magnetic flap level gauge gets stuck, which is why the float tends to sink continuously; this is also a common issue encountered in failures of magnetic flap level gauges ； II. The magnetic float is one of the key components of a magnetic flap level gauge; the float is magnetic, and the display panel shows the liquid level, which indicates that the float indeed has magnetic properties – this point can be ruled out. The float sinks; the possible reason is that the density value parameter is not provided accurately. The principle of float measurement in magnetic flap level gauges relies on the law of buoyancy; a float designed according to the density of the medium allows it to float even at low liquid levels, and as the liquid level rises, the float rises as well. The inner diameter of the stainless steel tube beneath the flap corresponds to the outer diameter of the float, whereas the outer diameter of the float is determined based on the density and pressure of the medium present in the area. Generally, the reasons for such measurement phenomena are mainly these two; therefore, when encountering such situations, users should first rule out these two possibilities. Solutions to the measurement errors of magnetic flap level gauges: In our daily use of magnetic flap level gauges, we often encounter a problem, namely measurement errors. Although these errors are not extremely significant, they still affect their practical application. Next, I will introduce to you the methods for addressing these measurement errors in magnetic flap level gauges. After long-term use, magnetic flap level gauges accumulate sediment of the medium inside their bodies, which can affect the proper functioning of the float; therefore, it is essential to clean them regularly. Before cleaning, first close the gas-liquid phase valves to remove any remaining substances from within the cylinder. After cleaning, assemble it as before; reverse the float if necessary. Replace the gasket to prevent leakage due to aging, and tighten the screws. Installation and use of magnetic flap level gauges: 1. After installation, first use the adjusting magnet to move slowly along the surface of the flaps, ensuring that the red side of all flaps faces the observer. 2. This product must be installed vertically, with a maximum deviation of ≤3°. 3. There should be no ferromagnetic materials within 200 mm around the body of the level gauge. 4. If the length of this product exceeds 4 meters, intermediate supports must be added during installation. 5. Before putting the magnetic flap level gauge into operation, the upper valve should be opened first, followed by slowly opening the lower valve, so that the medium can flow into the tank gradually, allowing the flaps to turn one by one to provide indication. And adjust the zero liquid level using the adjustment screw. 6. Before conducting a pressure test on the container, please close the valve connecting it to the level gauge. 7. During use, if individual flaps fail to function due to sudden changes in liquid level or other reasons, it is possible to correct this by adjusting the magnets.
