Magnetic flap liquid level gauge is a common liquid level gauge, which realizes the liquid level through the connecting pipe connected to the tank and the liquid level gauge to form a connector, as well as the principle of magnetic float buoyancy and the principle of magnetic coupling between the magnetic float and the display panel. On-site real-time measuring instruments for measurement. The characteristics of the magnetic flap level gauge are very distinct, including intuitive observation, clear, non-blocking, non-leaking, convenient installation, corrosion resistance, high reliability, and simple maintenance; It is very suitable for the detection and control of the liquid level of liquid media in various pressure (or open) liquid storage equipment (towers, cylinders, tanks, spherical containers and boilers) in industrial production processes. Magnetic flap level gauges have been widely used in electric power, petroleum, chemical industry, metallurgy, environmental protection, shipbuilding, construction, food and other industries, and the market coverage is very wide. The specific working method of the magnetic flap level gauge is that there is a magnetic floating ball in the vertical main pipe of the level gauge, and many small magnetic bodies are arranged on both sides of the tube (this magnetic body can be made of metal according to the working conditions. Flip sheet or plastic flip column), when the liquid level or water level changes; Due to the action of buoyancy, the floating ball will move up and down, and the magnetic body will be turned over due to the action of the magnetic pole. In addition to being affected by the material, the magnetic coupling is also greatly affected by the distance of the magnetic material. Generally speaking, the distance that can affect the magnetic coupling mainly refers to the distance between the magnetic float and the magnetic flip and the distance between the magnetic flip and the magnetic flip. The magnetic flips are generally placed in equidistant semi-circular card slots in the display panel, so the distance between the card slots is also the distance between the magnetic flips. What are the influences of the magnetic flap of the magnetic flap level gauge on the measurement Because the magnetic coupling is realized by the interaction force between the magnetic field and the magnetic field, and the magnitude of the force is closely related to the distance between the two magnetic fields. As far as the magnetic flip is concerned, the influence of the spacing of the magnetic flip on the measurement of the magnetic flip level gauge is mainly manifested in the following two points: 1. If the distance between two adjacent magnetic flips is too large, their force will be weakened, so that the whole display panel flips randomly, the liquid level display is inaccurate and the anti-interference ability is poor and other problems are easy to appear; 2. If the distance between two adjacent magnetic flap level gauges is too small, due to the too large force between them, it is easy for the two magnetic flaps to run out of the semicircular slot and be adsorbed together, which is inevitable. It will affect the accuracy of the magnetic flap level gauge measurement.
