Places where glass tube level gauges are used
Thread Content
A glass tube level gauge is a commonly used tool in liquid containers; it features simplicity, direct reading, and low cost. But its requirements for the working environment are quite strict, especially regarding temperature and pressure. First is stress. Glass tube level gauges are recommended for use at atmospheric pressure; the pressure should not exceed 0.6 MPa. Ordinary glass tubes cannot be used at pressures higher than this, but quartz tube level gauges can be utilized in such situations. Next is temperature; glass tube level gauges also have fairly high requirements regarding temperature. If the temperature in the environment is too high, or if the temperature of the liquid being measured is too high, it is very likely to cause the level gauge to break, resulting in severe damage. Therefore, when using it, be sure to pay attention to the effect of the ambient temperature. The temperature for ordinary glass tube level gauges should not exceed 70°C; if the temperature is too high, a quartz glass tube level gauge can be used. These two points represent the requirements that a glass tube level gauge has regarding its operating environment. Operating under normal temperature and pressure conditions is the most effective setup; if this cannot be ensured, it is necessary to stick to the specified pressure and temperature ranges in order to guarantee proper operation.
Glass tube level gauges are commonly used in various industrial containers or equipment to display and monitor the liquid level. The applicable locations mainly include the following categories: 1. Water treatment systems: such as water towers and water tanks, which are containers for storing water, and are used to control and monitor water levels. 2. Chemical industry: Used in equipment such as chemical reaction vessels and storage tanks to observe and monitor the liquid level of chemicals. 3. Food and beverage industry: Monitoring the liquid level of raw materials or products in storage tanks on production lines for beer, dairy products, beverages, etc. 4. Pharmaceutical industry: Used for level monitoring in equipment such as reactors and dissolution tanks during the production of drugs. 5. Oil and petrochemical industry: Monitoring the liquid level of oils and chemical raw materials in tanks, reactors, etc. 6. Electricity and energy: Devices such as boiler feed water tanks and steam generators require level gauges to ensure that the water level remains within safe limits. 7. Light industry and textiles: Level gauges are used to monitor the liquid level during the production and storage of dyes, paints, coatings, etc. Due to the limitations of the operating environment for glass tube level gauges, in high-pressure or high-temperature conditions, materials that are more resistant to high pressure and high temperatures, such as quartz tube level gauges, may be required to meet the demands of such special operating conditions. When the operating environment exceeds the range of operation of glass tube level gauges, other types of level gauges such as magnetic float level gauges or radar level gauges must be used to ensure safety and reliability. .

However, there are certain situations in which it cannot be used, including: 1. It is not suitable for use in environments with extremely high temperatures or pressures, as glass itself has limited tolerance for such conditions; in such cases, glass plate level gauges or quartz tubes are usually chosen as alternatives. 2. The measurement range is too large; overly long glass tubes require very high pressure levels, as the increased area subject to force makes them less resistant to compression. If glass tube level gauges must be used, it is recommended to manufacture and install them in sections, with each section having a length of no more than 2000 mm. 3. Some installation environments with complex operating conditions are also not suitable, such as mobile tanks. Using a glass tube level gauge here poses potential risks; even minor collisions during movement can cause the glass tube to break and lead to leaks. 4. Glass tube level gauges should not be used for flammable and explosive media. Although it is a purely mechanical level gauge, it is still made of glass; improper handling or impacts can cause it to break, leading to accidents. It is recommended to use glass panels or magnetic float level gauges with a higher safety factor. 5. It certainly cannot be used in situations that require remote monitoring and control, as a purely mechanical design cannot provide the signal output necessary for such purposes. 6. It is also impossible to install and use it in spaces that are too narrow; at least 220 mm of space must be maintained between the containers being tested in order to install this product. Moreover, when the installation space is too limited, it becomes inconvenient to use the valve.
