What are the advantages and disadvantages of magnetic flap level gauge

　　The magnetic flap level gauge is a widely used liquid level measuring instrument. It is widely used in many industries such as electricity, petroleum, chemical industry, environmental protection, shipbuilding, construction, etc. This is inseparable from its many advantages. However, there is no perfect thing without shortcomings in the world, and the magnetic flap level gauge also has many shortcomings. Therefore, understanding and knowing the advantages and disadvantages of the magnetic flap level gauge, so as to make the best use of its strengths and avoid its weaknesses, will help us better use the magnetic flap level gauge. Before introducing the advantages and disadvantages of the magnetic flap level gauge, let's talk about the working principle of the magnetic flap level gauge.

1. The principle of magnetic flap level gauge

　　The magnetic flap level gauge is based on the principle of communicating vessels and magnetic coupling to achieve real-time measurement and display of liquid level. When the measured liquid level in the container rises or falls, the magnetic float in the float also rises or falls, and the permanent magnet in the float drives the magnetic flap outside the float to flip 180° through magnetic coupling. The two sides of the flap are painted with different colors (usually red and white) to indicate the position of the liquid level. Generally, when the liquid level in the container rises, the flap changes from white to red, and when the liquid level in the container drops, the flap changes from red to white. The red and white intersection of the indicator is the actual height of the liquid level in the container.

2. Advantages of magnetic flap level gauge

　　Generally speaking, magnetic flap level gauges have the following characteristics and advantages:

　　1. Simple structure, intuitive reading, easy installation, low maintenance cost and high cost performance.

　　2. It has good sealing and vibration resistance, high reliability, and can adapt to operations under conditions of large liquid level fluctuations.

　　3. The magnetic steel corrector is compact and easy to use, and can be adjusted at will on site.

　　4. By adding remote transmission unit components, the on-site indication, remote transmission, and alarm control switch are integrated to realize automatic liquid level control and remote control.

　　5. It can be equipped with steam jacket, electric heating, heat preservation/insulation and anti-frost additional devices, and can be applied to various complex working conditions.

　　6. It has a wide range of applications and various forms, and is suitable for measuring liquid levels under various working conditions (such as high temperature, high pressure, and corrosion).

3. Disadvantages of magnetic flap level gauge

　　In addition to the above advantages, magnetic flap level gauges also have the following disadvantages and shortcomings:

　　1. The accuracy is low, and the measurement accuracy is generally between ±5.0mm~±10mm.

　　2. There is a certain range limitation. The large-range magnetic flap level meter is inconvenient to transport and the installation volume is relatively large.

　　3. After long-term use, if there is sediment in the body of the magnetic flap level gauge, it will affect the float's movement up and down along the protective tube outside the waveguide. To avoid getting stuck, it must be cleaned regularly. (Warm Tips: Before cleaning the magnetic flap level gauge, turn off the valve and sweep away the remaining material in the cylinder. After cleaning, install it as it is, turn the float upside down, replace the sealing gasket to prevent aging and leakage, and tighten the screws.)

　　The above are the main advantages and disadvantages of the magnetic flap level gauge. The magnetic flap level gauge produced by Jiwei Automation has the following advantages in addition to the common advantages of magnetic flap level gauges compared with other similar products:

　　1. The display panel and flap are specially designed to be widened, which greatly increases the viewing distance and viewing angle, and the scale and numbers are thicker and clearer, with a beautiful appearance.

　　2. The unique display panel end cover design and glass sealing process make the protection level of the whole machine reach IP66/IP67.

　　3. The matching SW-11 magnetic switch and Reed-11 reed switch remote transmitter have both passed the explosion-proof and intrinsic safety double explosion-proof certification, with the explosion-proof level Ex d IIC T6 and the intrinsic safety level Ex ia IIC T6, which are both high explosion-proof levels among similar products in the industry. Used in conjunction with the Flap-11 series magnetic flap level gauge, it can realize automatic level control and remote control.

　　4. It can be equipped with steam jacket, electric heating, heat preservation/insulation and anti-frost additional devices, and can be applied to various complex working conditions.

　　Since the magnetic flap level gauge has its own shortcomings and deficiencies, and the working conditions of users vary greatly, we need to make the best use of the strengths and avoid the weaknesses according to the characteristics of the magnetic flap level gauge itself and the specific working conditions, and strive to solve the problems raised by customers. Jiwei Automation can be customized according to the different working conditions of users to better meet the needs of customers. For example, according to the different chemical properties of the liquid, floats of different materials can be selected to adapt to it; according to the different densities of the liquid, floats of different volumes and weights can be selected to match it to achieve the best measurement accuracy. The different applications of various product models and materials are to adapt to the different chemical properties of the measured liquids, while ensuring the reliability of the product, and saving costs for users to the maximum extent, so that the product has the highest cost performance.
