China is home to some of the most iconic and historically rich museums in the world, each offering a unique glimpse into the country’s vast cultural heritage. Among them, the National Palace Museum in Taipei, the Palace Museum in Beijing, and the Nanjing Museum stand out as three of the most significant institutions. These museums not only preserve invaluable artifacts but also serve as cultural landmarks that reflect the artistic and historical evolution of China.
The Taipei National Palace Museum, located in Shuangxi, on the northern coast of Keelung, is one of the most renowned cultural institutions in the world. Established in 1962 and completed in 1965, it was designed in the style of traditional Chinese palaces, with four-story architecture, white walls, and green tiles. The building features a plum-shaped courtyard and an impressive six-pillar archway, embodying the grandeur and elegance of classical Chinese design. With over 20 exhibition halls, the museum houses a vast collection of treasures from the imperial collections of the Qing Dynasty, including paintings, calligraphy, ceramics, and ancient relics. Spanning approximately 16 hectares, the museum is surrounded by natural beauty, and its traditional colors and imposing structure make it a symbol of Chinese heritage.
Located within the Forbidden City in Beijing, the Palace Museum is a monumental complex that has served as the imperial palace for both the Ming and Qing dynasties. Founded on October 10, 1925, it is not only the largest ancient cultural and art museum in China but also one of the most important historical sites globally. The museum’s collection, which includes over 1.8 million items, covers nearly every aspect of Chinese civilization, from ancient scrolls and artifacts to rare treasures. Although some of the Qing dynasty artifacts were relocated to Taipei during the late 1940s, the Beijing museum has continued to expand its holdings through donations, archaeological discoveries, and acquisitions. It remains a crucial center for the preservation and study of Chinese history and art.
Meanwhile, the Nanjing Museum, originally known as the National Central Museum when it was established in 1933, is another key player in China’s cultural landscape. Designed by renowned architect Xu Jingzhi and modified by Liang Sicheng, the museum’s main hall is modeled after the Liao Dynasty Palace and showcases a blend of traditional Chinese architectural elements with modern design principles. The museum, which once aimed to have three separate halls—covering “humanities,†“crafts,†and “natural†themes—only fully realized the “Humanities Pavilion.†Today, it is the second-largest museum in China and one of the three major museums, known for its comprehensive collection of historical and artistic artifacts. After recent expansion, the museum now features a “one-hospital six-hall†layout, including the History Hall, Special Exhibition Hall, Digital Hall, Art Gallery, Non-heritage Hall, and more, making it a dynamic space for both education and research.
The liquid level transmitter can convert the changes of various level parameters into analog signals, and transmit them to the control room remotely for centralized display, alarm or automatic control of secondary instruments or computers. Its good structure and installation method can be applied to the continuous detection of liquid level, material level or material level under special conditions such as high temperature, high pressure, strong corrosion, easy crystallization, anti-clogging, anti-cold junction, and solid powdery and granular materials. , can be widely used in detection and control in various industrial processes.
Liquid level transmitters can be applied to liquid Level Measurement and control in industrial sites, rural water supply and sewage treatment, petroleum, chemical industry, power plants, hydrological monitoring, reservoirs, dams, hydropower construction and other fields of liquid level measurement and control. Liquid level transmitters have input type, straight rod type, flange type, threaded type, inductive type, screw-in type, floating ball structure design, with anti-blocking type design, simple device, convenient use and strong interchangeability , The high-quality sensor has high sensitivity and fast response speed, accurately reflects the slight changes in the flow or static liquid level, and has high measurement accuracy.
Advantages of Level Transmitters
1. The device is simple, easy to use, and has strong interchangeability.
2. It is suitable for measuring the liquid level and interface of the liquid medium in the container. In addition to on-site instructions, it can also be equipped with remote transmitters, alarm switches, and complete detection functions.
3. The reading is intuitive and eye-catching, and the direction of the observation indicator can be changed according to the user's needs.
4. The measurement range is large, not limited by the height of the storage tank.
5. The indicating mechanism is completely isolated from the measured medium, with good sealing performance, high reliability and safe use.
6. Simple structure, convenient installation, convenient maintenance, corrosion resistance, no power supply, explosion-proof.
7. The high-quality sensor has high sensitivity and fast response speed, accurately reflects the slight changes of flowing or static liquid level, and has high measurement accuracy.
8. With intrinsically safe explosion-proof and isolated explosion-proof capabilities, it can be used in various dangerous places.
9. With anti-blocking design, it can realize the measurement of the liquid level of paste medium.
10.100% equal division scale, LED/LCD indicator head, very convenient to read on site.
11.4~20mA two-wire signal transmission, strong anti-interference ability and long transmission distance.
12. Exquisite and unique zero point, full scale, and nonlinear compensation ensure the accuracy and stability of the instrument within the range of operating conditions.
13. The Pressure Sensor directly senses the liquid level pressure and is not affected by the foaming and accumulation of the medium.
14. Wide range of tested media can be used, such as oil, water and paste, with certain anti-corrosion ability.
Classification of liquid level transmitters
1. Single flange liquid level transmitter
Single-flange liquid level transmitters have flat flanges and flange liquid level transmitters with insert barrels, both of which are suitable for single-flange liquid level transmitters that use the gravity of the medium to be measured to measure the height of the liquid level. For medium with high viscosity and easy crystallization, it is generally used in open containers or equipment installations.
2. Double flange liquid level transmitter
The double-flange liquid level transmitter is a Differential Pressure Transmitter, which provides a reliable measurement method to prevent the measured medium from directly contacting the isolation diaphragm of the transmitter. The main features are the need to isolate the high-temperature medium from the transmitter, the measurement medium has a corrosive effect on the sensitive components of the transmitter, the suspension liquid or high-viscosity medium, the measured medium solidifies or crystallizes due to changes in the environment or process temperature, and the measured medium is replaced It needs to be strictly purified to measure the first class. Double flange liquid level transmitter is mainly used in the measurement of liquid level in sealed pressure vessels.
3. Submersible liquid level transmitter
The submersible liquid level transmitter has rod type and arm type. Its principle is based on the principle that the measured liquid static pressure is proportional to the height of the liquid. It uses the piezoresistive effect of diffused silicon or ceramic sensitive elements to convert the static pressure into electricity. Signal. After temperature compensation and linear correction, it is converted into 4~20mA current signal output. Due to the characteristics of this transmitter, such as convenient installation, strong adaptability, etc., it can perform high-precision measurement from water, oil to paste with high viscosity, and is not affected by the foaming and accumulation of the measured medium. It is generally used in open Devices for mouthpieces or equipment.
