The birth of 3D level scanner completely changed the traditional principle of single-point measurement technology, led the world level measurement field to the "3D era" with a brand-new visual dimension, and truly reached the technical peak of media visualization and process intelligence. And with the trend of rapid spread, it goes deep into the field of level measurement in various industries around the world and plays an important role. The system is the only innovative product that can accurately measure the solid material and volume, which is not affected by the material type, physical and chemical properties, the type and size of storage room, open-air warehouse or silo, and is suitable for material level measurement in very harsh and high dust storage environment. What does 3D horizontal scanner bring us? Accurate collection, measurement, real-time monitoring and analysis, load investigation, low-carbon energy saving and emission reduction control effect is good! Working principle: The three-dimensional horizontal scanner monitors the time/distance/direction of each echo based on the low-frequency pulse wave emitted by the two-dimensional array beamformer. The digital signal processor of the equipment samples and analyzes the pulse echo signal received from the material surface to generate a three-dimensional image of the actual distribution of the material surface. The image processes information by a proprietary computing method, and generates a 3D image, which can be displayed on the screen of a remote computer. Based on this, the equipment can accurately detect the real material level. Technical features 3D level scanner can monitor any bulk solid materials stored in any container, including large open-air warehouses, solid material storage rooms, storage yards, warehouses, etc., and has a wide range of application environments and occasions. The low-frequency pulse wave emitted by the antenna horn can penetrate the suspended dust, unlike other technologies that have "suspicious" signals when measuring in very harsh environment. The pulse wave signal contains a proprietary self-cleaning function, which can prevent materials from adhering to the inner surface of the antenna horn. So as to ensure long-term and reliable operation with very low maintenance in any harsh environment. At present, there are many principles of various liquid level measurement technologies in the world, including: laser, radar, ultrasonic, heavy hammer, radio frequency admittance, capacitance and so on. The above products are not completely designed for material measurement, but are all based on the principle of single point measurement. In the aspect of material level measurement, the application effect is not ideal and many problems are exposed. Because the material always presents an irregular surface. Therefore, accurate measurement is always an unsolved problem. In actual use, the effect is naturally not ideal. At present, the working conditions and environmental problems of pulverized coal bin, limestone powder bin, cement bin and dry ash bin cannot be directly understood. Through long-term field investigation and analysis, the factors affecting the correct measurement of material level are: 1. The material particles in the powder bin are fine, which are dispersed when feeding powder, fine dust flutters and the density of powder pile is low. The difference between powder and non-powder tends to be blurred, which seriously affects the measurement of ultrasonic or other electromagnetic wave methods and even leads to failure. 2. Different compositions and humidity of various materials lead to differences in their physical properties, especially the bulk density of powder at different heights is very different, which cannot be measured by a unified physical quantity, which has a great influence on continuous measurement. 3. Irregular powder discharging, powder adding, powder collapsing and other phenomena in the warehouse have a great destructive force, and at the same time, the sensor bracket in the warehouse can be bent and folded, even damaging the equipment. 4. The warehouse wall is prone to material hanging, and the material presents uneven and irregular surface. Roof caving is easy to happen, and the real level cannot be obtained. It can be seen that the level measurement is absolutely an insurmountable technical problem in the world at present. The limitations of existing liquid level measurement technology relative to 1 measurement method are summarized. Manual liquid level measurement is very troublesome/labor-intensive. Operators often need to go to the scene to observe the changes of materials, which is labor intensive. Even in some cases, it is impossible to observe at all. Ultrasonic dust influence/concave-convex surface influence has little maintenance. Its disadvantage is that the drifting dust interferes with the ultrasonic measurement, and the provided measurement data can not confirm its true accuracy. The radar dielectric constant/dust influence/concave-convex surface influence is required to be small during maintenance. Its disadvantage is that the drifting dust interferes with the radar wave measurement, and the provided measurement data can not confirm its true accuracy. Influence of radioactive probe dust/concave-convex surface The radioactive isotope-137 is used as the radiation source to generate gamma rays to detect the object level. High reliability. Its disadvantage is that users have doubts about gamma rays, so they generally entrust instrument manufacturers to maintain them; Abandoned radiation sources must be disposed of by special environmental protection agencies. Comparison of existing liquid level measurement technologies 2 Advantages of ultrasonic level gauge: Non-contact limitation: dust influence/concave-convex surface influence Non-contact radar level gauge Advantages: Non-contact limitation: dielectric constant required/dust influence/concave-convex surface affected guided wave radar level gauge Advantages: Measurement limitation at a certain point: dielectric constant required/suspension material/tensile force affected laser level gauge Advantages: Non-contact limitation: dust influence/ Concave-convex surface affects radio frequency admittance level gauge Advantages: point contact limit: required dielectric constant/time drift/temperature drift/hanging material/pulling weight level gauge Advantages: direct measurement limit: manual control limit: buried hammer/rope-wound gamma-ray level gauge Advantages: non-contact, stability limit: pollution weighing level gauge Advantages: measurable mass volume limit: earthquake problem/unknown material surface condition/high price. When using the above equipment to measure the material level, although there are real-time material level data, it is impossible to understand the actual situation in the warehouse and make a correct judgment on the accuracy of the measured data. Manual measurement still needs to calibrate the measurement data of the equipment twice, which leads to the measurement equipment not being put into automatic operation normally. The birth of 3D horizontal scanner completely changed all this! 3D horizontal scanner can display the random changes of material shape in real time with 3D images, and can be widely used in challenging measurement and control fields that traditional technology cannot enter. The 3D image with higher accuracy shows the most real and absolute surface level, volume and material quality, and eliminates the error caused by single point measurement in traditional surveying and mapping. The more easy-to-operate 3D horizontal scanner system provides very intuitive 3D images and easy-to-read data, making it the most convenient and effective horizontal measuring instrument on the market at present. The sensor is tighter. The 3D level scanner has a built-in temperature sensor, which monitors the ambient temperature through software and sets temperature compensation to eliminate the measurement error caused by the temperature rise caused by the long-term operation of the sensor. The 3D horizontal scanner with higher cost performance can be used to measure solids and liquids, providing you with unprecedented accurate data, more comprehensive performance and higher cost performance. Technical advantages of 3D horizontal scanner ● The only product with real media visualization and intelligent process; ● A revolutionary breakthrough to replace and surpass radar level gauge or ultrasonic level gauge; ● Scan the material surface (hundreds of grid points), and measure the average value of multiple points no matter how irregular the material surface is; Excellent high-concentration dust transmission technology, low-frequency pulse wave technology and non-contact measurement; No moving parts, no corrosion risk, suitable for cement, steel, electricity, storage and transportation, food, chemical industry and medicine; ● It can detect solid materials such as powder, granular materials and pellets without special calibration; ● It can be used in high silos-the detection range can reach 70M ● It can give early warning to the materials adhering to the silo wall, with high cost performance; ● During the initial installation, connect our customer support engineers remotely, so that specific field scanners can be customized for the best performance configuration. Accuracy comparison between 3D horizontal scanner and single-point measuring equipment ● Silo size: diameter = 10M, height =20M ● Vertebral body with 45 degrees up and down; ● Accuracy of 3D horizontal scanner =1.55%; ● Accuracy of single-point measuring instrument = 16%. The working frequency of the 3D horizontal scanner ● The 3D horizontal scanner uses a frequency of 2 to 7KHz; ● At this low frequency, the beam coverage angle is wide (70); ● Dust infiltration-When working in high dust and high humidity environment, low-frequency waves can still maintain good results. Cost control-do it right in many occasions, such as burning a lot of coal in the production process of thermal power plants, and burning millions of tons a year in large power plants is worth hundreds of millions of yuan. In the three links of coal supply, coal burning and coal storage in power plants, coal storage inventory has always been a troublesome problem. But this is indeed an important link in production management, which has a direct impact on the economic indicators of power plants. At present, the measurement of coal storage in coal yard of thermal power plant generally adopts manual measurement method, that is, the coal pile is shaped by bulldozer and manually pushed into an approximate trapezoid, and then manually measured by theodolite and meter ruler. This method not only consumes a lot of man-hours and manpower, but also is inaccurate in measurement, which is greatly influenced by human factors. The 3D horizontal scanner provides a win-win strategy for production departments and business departments: it can provide accurate inventory monitoring of daily progress and sunrise, production can be carried out reliably as planned, and at the same time provide real-time and key data to help financial and other managers make a real evaluation of actual costs. By understanding the real-time changes of inventory materials, managers of production departments and commercial departments can make correct decisions at any time. Safety in production-it is very important that steel silos are prone to collapse due to uneven stress on the silo wall, which may be caused by deterioration of suspended materials or symmetry of incoming and outgoing materials, and adhesion of materials to the silo wall. The 3D horizontal scanner can provide visual detection of all these situations before the adhered materials threaten the overall structure of the silo. Help the production manager to maintain the silo correctly, avoid the huge loss of operating benefits, cause the interruption outside the production, and save expensive emergency remedy expenses. Production Tracking and Accurate Monitoring 3D level scanner makes process control, inventory management, tracking drawing and forecasting simple and accurate. Efficiency is improved, waste is reduced, production is smooth, and transportation is optimized, so the expensive emergency treatment cost is correspondingly reduced. Operational benefits 3D level scanner can detect the volume, the highest level and the lowest level of stored materials. This has great added value, because the alternative scheme of detecting low-point material level is difficult to install and maintain. The 3D level scanner, which is remotely connected with ERP and other systems, can be connected with most automatic control systems to realize remote monitoring and data transmission, enter the rapidly changing real inventory environment, and help production and operation managers make wise decisions in time. This not only greatly reduces the operation time, but also saves workers' insurance compensation caused by dangerous manual measurement. The more materials stored in the warehouse, the higher the added value of the 3D level scanner, and the greater the impact on cost control. The application industries of three-dimensional material level scanner include cement and aggregate raw meal, clinker warehouse, coal warehouse and so on. Steel-raw material silos, coal silos, ore silos, etc. , coking, coal silo, ash storage or fly ash, pulp and paper, petrochemical industry, mining, metallurgy, non-ferrous metal smelting, food processing, grain, seeds and feed, aggregate industry, chemical processing, bioenergy and plastic production. 3D Level Scanner |3D Level Scanner |3D Level Volume Scanner |3D Level Meter |3D Visible Level Volume Detector | Large Bulk Volume Measuring Instrument | Data Download Interface of Large Bulk Coal Volume Measuring System _3D Level Scanner _ Product Book.
