The common materials for industrial instrument housings are plastic, aluminum alloy and stainless steel. Stainless steel, as a high-quality metal material, occupies an important position in the manufacture of industrial instrument housings. Its excellent corrosion resistance, food and drug health and safety, mechanical properties and aesthetics, making the stainless steel shell in the industrial instrumentation is widely used. However, different working conditions on the instrument housing material has different standard requirements, in the procurement of industrial instruments we can according to the working conditions of the environment and the relevant standards to choose the instrument housing material.The advantages and disadvantages of the above common housing materials and the applicable working conditions are described below:Plastic housing:Industrial instrument housings made of plastic have light weight, low cost, good insulation, and the processing and manufacturing of plastic is relatively easy. In addition, plastic material also has corrosion resistance, especially suitable for some special anti-corrosion working conditions. However, the plastic material is relatively brittle, not hard enough, easy to be damaged by external forces, but also easy to aging, relatively short life. Plastic shells are mainly used in conventional working conditions, such as: electroplating, pharmaceutical, chemical areas, no explosion-proof requirements and corrosive or insulating requirements of the environmental conditions.Aluminum housing:Aluminum alloy has many advantages in industrial instrument housings, such as high strength, light weight, corrosion resistance, good thermal conductivity and plasticity. However, it is relatively high cost, difficult to process and requires high welding process. Aluminum alloy housing can be used in most working conditions due to its unique material characteristics, such as; food, pharmaceutical, petroleum, chemical, water conservancy, shipping and other industries, but in the strong acid, alkali corrosive chemicals containing special working conditions can not be used.Stainless steel housing:Stainless steel shell in the industrial instrumentation with superior corrosion resistance, strong and stable mechanical properties, beautiful and easy to clean and other advantages, but compared to plastic and aluminum alloy, stainless steel shell price is much higher. Stainless steel shell has high strength and good toughness, able to withstand large external impact and extrusion; able to resist acid, alkali, salt and other corrosive media, in harsh environments can still maintain stability and durability. More used in food, pharmaceutical, coal, petroleum, chemical, ship, ocean engineering and other environmental conditions. Stainless steel shell for some special requirements of the working conditions is a must, such as coal mines, ocean engineering, etc. on the stainless steel industrial instrument housing has clear requirements. In the super pressure, corrosion resistance, aluminum alloy and plastic material shell is unable to meet the relevant standard requirements. In the food, pharmaceutical industry, industrial instrumentation shell selection, due to considerations of aesthetics, health and safety and easy to clean and other characteristics will also be designated to use stainless steel shell. Stainless steel shell with its excellent performance and wide range of adaptability, in the modern industrial instrumentation is widely used, especially some of the need to prevent strong corrosion, high security requirements and food hygiene and other special conditions.The kaidi range has been expanded with the addition of stainless steel housings, available in 304 or 316L.

In today's era of growing energy demand, the fuel production industry plays a crucial role. As an advanced measuring equipment, Radar level meter plays an indispensable role in all aspects of fuel production, providing a strong guarantee for the efficient, safe and stable operation of fuel production.Radar level meter is based on the radar principle, which measures the material level by transmitting microwave signals and receiving the reflected signals back. It has many advantages such as high precision, non-contact measurement, not affected by the characteristics of the medium, which makes it widely used in fuel production. In the fuel storage link, the role of radar level meter is particularly prominent. Fuel usually requires a large number of storage tanks for storage, accurately grasp the level of fuel in the tanks for the rational arrangement of production planning, to ensure the stability of supply is essential. Traditional level measurement methods may be affected by the complex environment inside the tanks, such as high temperature, high pressure, steam, etc., resulting in inaccurate measurement. While radar level meter can work stably in harsh environments, its high-precision measurement capability can monitor the fuel storage volume in real time, avoiding safety accidents caused by too high or too low levels. For example, in petroleum refineries, through the accurate measurement of crude oil storage tanks by radar level meter, operators can timely adjust the flow of incoming and outgoing oil to ensure the safe operation of storage tanks and prevent the occurrence of oil spillage accidents.Radar level meters also play a key role in the fuel production process. Take coal gasification production as an example, in the gasifier, coal and oxygen chemical reaction to generate syngas. In this process, it is necessary to accurately control the amount of raw coal added and the material level in the gasifier. The radar level meter can monitor the material level in the gasifier in real time, providing accurate data for the operator, so as to adjust the coal adding speed and oxygen flow rate in time to ensure the stability of the gasification reaction. If the material level is not properly controlled, it may lead to too high or too low temperature in the gasifier, affecting the gasification efficiency, and even triggering problems such as slagging in the furnace, affecting the normal operation of production. In the fuel transportation process, the radar level meter can also play an important role. For example, in the process of transporting oil in tanker trucks, through the installation of radar level meters, you can monitor the oil level changes in the tanker truck in real time to ensure the safety of the transportation process. At the same time, according to the oil level information can be reasonably arranged transportation routes and unloading plans to improve transportation efficiency.In short, radar level meter has an irreplaceable role in fuel production. It can not only improve production efficiency, reduce production costs, but also to ensure the safety and stability of the production process.

In this day and age, the frequent occurrence of extreme weather has posed a great challenge to the deployment of water resources. Droughts, floods and other extreme conditions are staged alternately, making the rational allocation and effective use of water resources has become a key issue related to people's livelihood, ecology and development. In this context, the radar level meter is playing an important and indispensable role in providing accurate data support for water resources allocation, like a wise “water steward”.With its unique working principle and excellent performance, the radar level meter shows many advantages in the field of water resources allocation. It is based on the propagation characteristics of radar waves and measures the liquid level height by transmitting and receiving radar waves. This non-contact measurement avoids corrosion and clogging problems that may occur in traditional level meters due to direct contact with the liquid, and greatly improves the accuracy and reliability of the measurement. Whether in harsh natural environments or complex industrial application scenarios, radar level meters can work stably and provide real-time, accurate data for water resource allocation.Radar level meters are especially useful in extreme weather. When experiencing dry weather, water resources become extremely scarce, every drop of water is precious. At this time, the radar level meter can be reservoirs, lakes and other water sources of water level for accurate monitoring. Through the real-time grasp of the water level changes, the water conservancy department can rationally arrange the water plan, prioritize the protection of residential water and important industrial production water. For example, according to the data fed back by the radar level meter, when the water level drops to a certain degree, the agricultural irrigation water strategy can be adjusted in a timely manner, the use of water-saving irrigation methods, to avoid the waste of water resources, to ensure that the limited water resources are optimized use. In the event of flooding, the radar level meter can play a key role in early warning and drainage scheduling. It can monitor the water level of rivers and lakes in real time, and issue early warning information in advance, so that the relevant departments and residents have sufficient time to prepare for flood control. At the same time, based on the level data, the water conservancy department can scientifically dispatch water conservancy engineering facilities, such as opening gates to release flood water and activating flood storage zones, etc., which effectively reduces the threat of floods to the downstream areas and protects the safety of people's lives and properties. In addition to the application in emergency situations, the radar level meter also has an irreplaceable role in the daily management of water resources. It can carry out real-time monitoring of the city's water supply system, sewage treatment facilities, etc., to ensure the normal operation of water supply and drainage. Through the monitoring of sewage level, the sewage treatment plant can reasonably adjust the operating parameters according to the actual treatment capacity, improve the efficiency of sewage treatment, and prevent sewage overflow from causing environmental pollution.With the continuous progress of science and technology, the performance of radar level meter is also constantly improving. Its measurement accuracy is getting higher and higher, its anti-interference ability is getting stronger and stronger, and it can adapt to more complex and changing environmental conditions. In the future, we have reason to believe that the radar level meter will play a more important role in the field of water resources allocation, to deal with extreme weather brought about by the challenge of water resources to provide more powerful support.

In the processing and production of wine, accurate level measurement is essential to guarantee product quality, optimize production processes and ensure production safety, in which radar level meters play an indispensable and key role.The brewing of wine begins with the processing of raw materials and fermentation. In a large-scale fermentation vessel, the raw materials are gradually transformed into alcohol and various flavor substances under the action of microorganisms. During this process, the level of the fermentation liquid needs to be monitored in real time and accurately. A radar level meter accurately determines the liquid level by transmitting microwave signals and receiving their reflected waves. It is able to penetrate the vapor and foam layers above the fermenter without interference from these complex conditions, providing accurate feedback on the real-time position of the fermentation broth. This allows the operator to accurately control the fermentation process based on changes in the liquid level, for example, to determine whether the fermentation is sufficient, whether the temperature needs to be adjusted or whether other auxiliary materials need to be added, etc. This ensures that the fermentation of each batch of wine is carried out in an optimal state, and lays a solid foundation for the quality of the subsequent batches of wine.                                                                                                                                                                        (Source: Internet)When fermentation is completed and the distillation stage is reached, the role of the radar level meter remains significant. During the distillation process, liquors of different alcoholic strengths are separated and collected into different storage containers. At this time, the radar level meter can accurately measure the liquid level in each storage tank, so that the staff can accurately grasp the output and storage capacity of each batch of distilled spirits. At the same time, in the process of blending different degrees of the original liquor to obtain the target alcohol precision, the accurate liquid level data provided by the radar level meter is an important basis for realizing accurate blending. Through the linkage between the automated control system and the radar level meter, the original wines in different containers can be precisely extracted and mixed in accordance with the preset recipe ratio, so as to ensure the consistency and stability of the final product in terms of alcohol precision and taste, and to satisfy the consumers' stringent requirements on the quality of wines.Radar level meters continue to play an important role in the storage phase of wine, both for short-term temporary storage and long-term aging. For long-term storage of wine, keeping the liquid level in the storage container stable is the key to preventing volatile loss of wine and the intrusion of external impurities. Radar level meter can monitor the liquid level change in the storage tank in real time, once the liquid level is found to be abnormally decreased, it may indicate that there is a risk of leakage in the storage tank, and the staff can take timely measures to carry out overhaul and maintenance to avoid the quality decline, safety hazards, and economic losses caused by the leakage of wine. Moreover, in the process of wine turnover, accurate liquid level measurement helps to reasonably arrange the inventory space, improve the utilization rate of storage, optimize the logistics and distribution plan, and make the whole wine production and processing supply chain run more efficiently and smoothly.Radar level meter with its high precision, non-contact measurement, adaptability and many other advantages, comprehensively integrated into the wine processing of each key link, to protect the quality of wine products, improve production efficiency, to ensure production safety of the right hand, for the modernization of the wine industry and the sustained and stable output of high-quality wines to provide a solid technical support.
