In the vast system of industrial production, liquid level measurement is like a precise "intelligent eye", which is a key link to ensure the stable and efficient operation of the production process. From large storage tanks in the petrochemical industry, to boiler drums in the power industry, and to production tanks in the food and beverage industry, accurate liquid level detection is of vital importance. The magnetic flap level gauge, with its unique working principle and outstanding performance advantages, has become a trusted liquid level measurement tool in many industrial fields.
The design of the magnetic flap level gauge is inspired by the principle of buoyancy and magnetic coupling. It mainly consists of a main tube connected to the measured medium, a magnetic float with a permanent magnet inside, and an external display panel (composed of red and white dual-color magnetic flipping columns). When the liquid level in the measured container rises or falls, the magnetic float inside the main tube moves up and down synchronously due to the effect of buoyancy. In addition, the permanent magnet inside the float drives the magnetic flipping columns on the external display panel to flip 180° through the magnetic coupling effect. When the liquid level rises, the flipping columns change from white to red; when the liquid level falls, the flipping columns change back from red to white. Through the color change of the flipping columns, people can intuitively and clearly read the liquid level height, realizing the visual monitoring of the liquid level. This non-contact measurement method not only avoids failures of traditional level gauges caused by mechanical friction but also ensures the safety and reliability of the measurement process, enabling stable operation even in harsh industrial environments.
The display panel of the magnetic flap level gauge adopts a unique design, with the scale marks and numbers to greatly improve the visible distance and angle. Whether it is an outdoor storage tank under strong light or an indoor production workshop with dim light, operators can easily and quickly read the liquid level data. The dual-color flipping column design is more eye-catching and can be clearly distinguished under various ambient light conditions, providing great convenience for liquid level monitoring in the production process.
Adopting a modular design, the main structure is simple. The main components include a main pipe, a float, a display panel, and a connecting flange, with no complex moving parts. The installation methods are flexible and diverse: the side-mounted type is suitable for large vertical containers, such as oil storage tanks and fire water tanks; the top-mounted type is designed for scenarios with limited top openings, such as spherical tanks and horizontal tanks. In addition, the level gauge is equipped with a stop valve, so when cleaning, maintenance, or component replacement is needed in the later stage, the operation can be carried out without shutting down the machine, effectively reducing maintenance costs and time, and improving production efficiency.
It has excellent pressure and temperature resistance performance. The maximum working pressure can reach 16MPa, and the working temperature range covers -20℃ to 350℃, which can adapt to extreme working conditions such as high-temperature steam and low-temperature liquefied gas. For viscous or easy-to-solidify media, steam jackets or electric tracing devices can also be optionally equipped to ensure the fluidity of the medium during the measurement process and guarantee the measurement accuracy. It also performs well in anti-corrosion and explosion-proof aspects. For strong corrosion environments, lined and plastic-type level gauges have been launched, which can withstand strong corrosive media such as hydrofluoric acid and concentrated sulfuric acid; at the same time, it has passed the dual certification of flameproof type (Exd IIC T6 Gb) and intrinsic safety type (Ex ia IIC T6 Ga), with a protection level of IP66/IP67, and can be safely used in flammable and explosive places such as oil and gas storage and transportation, and pharmaceutical industries.
Relying on its stable structure and advanced measurement principle, the magnetic flap level gauge has high measurement accuracy, and the error can be controlled within a small range. During long-term use, it is not easily affected by external interference and can always maintain reliable performance, providing accurate liquid level data for industrial production and effectively avoiding equipment failures, production accidents, and other problems caused by abnormal liquid levels.
In the process of petroleum refining and chemical production, the liquid level monitoring in various storage tanks and reaction kettles is of direct importance. The magnetic flap level gauge can display the liquid level height of media such as crude oil, finished oil, and chemical raw materials in real time. It can be combined with a magnetic switch to realize the high and low liquid level alarm function, effectively preventing overflow or emptying accidents. For example, in the storage tank area of a large oil refinery, through the magnetic flap level gauge combined with an automatic control system, remote monitoring and automatic liquid replenishment can be realized, greatly improving the safety and management efficiency of production.
The water level of the boiler drum is a key indicator for the safe operation of a power plant. The magnetic flap level gauge, through its high-temperature-resistant design and steam jacket heat preservation measures, can accurately measure the high-temperature water level above 200℃, and promptly detect and avoid boiler dry burning or water flooding accidents caused by false water levels. After a thermal power plant adopted an advanced magnetic flap level gauge, the water level measurement error was significantly reduced, and the operation stability was greatly improved, ensuring the continuous and stable supply of power production.
In a hygienic production environment, the hygiene requirements for liquid level measurement equipment are extremely high. The plastic-type magnetic flap level gauge adopts an FDA-compliant material body and food-grade sealing rings, and its fully enclosed structure effectively prevents bacterial growth. It is widely used in the liquid level monitoring of equipment such as beer fermentation tanks and dairy storage tanks, ensuring the hygiene, safety, and quality stability of the food and beverage production process.
With its outstanding performance, wide applicability, and reliable quality, the magnetic flap level gauge plays an irreplaceable role in the field of industrial liquid level measurement. With the continuous advancement of the industrial automation process and the continuous innovation of technology, the magnetic flap level gauge is also constantly upgrading and developing, injecting new vitality into the intelligence, high efficiency, and safety of industrial production. It is believed that in the future, it will continue to assist the development of various industries and become a pillar in the field of industrial liquid level measurement.
