The radar level gauge is a new high-tech level gauge product since the traditional level gauge. It can emit microwave pulses with very low energy and very short wavelength, and then transmit and receive through the antenna system, transmitting and reflecting the beam. Each point of Cao Yong's ultrasonic sampling method is collected, and the signal is processed by the intelligent processor to obtain the distance between the probe and the liquid surface, and then the processed data is transmitted to the display or the alarm system for the staff to understand. Radar level gauges are suitable for non-contact continuous measurement of liquids, slurries, and particulate matter, solids, etc. This is similar to ultrasonic level gauges. Ultrasonic level gauges are also non-contact measurement of objects. However, the practicality of the radar level gauge is stronger than that of the ultrasonic level gauge. In addition to the ultrasonic energy measurement, the radar level gauge can also accurately measure, and can also change some temperature and pressure greatly, even inert gas and In the case where volatilization exists, it can be accurately measured, and it is unmatched by other liquid level meters. It uses microwave pulse measurement and works well in the industrial frequency range. The beam energy is low, can be installed in various metal, non-metallic containers or pipelines, no harm to the human body and the environment, and has many advantages. Therefore, radar level gauges will be accepted by more and more enterprises. The future market is also very broad. Electromagnetic flowmeter http://
Radar level gauge is a kind of sophisticated, high-tech instrument. We should pay attention to it when using it. Generally, there are several points: First, the measurement range starts from the point where the beam touches the bottom of the container. However, under special containers, such as irregular containers, concave or tapered bottoms, radar level gauges are difficult to measure accurately. Of course, the containers used in our lives are very regular. Second, if the medium is low dielectric constant, when it is at low liquid level, or the bottom of the tank is visible, in order to ensure the accuracy of measurement, it is generally necessary to position the zero point at the lowest position, so that it can be accurately measured. Third, in theory, the measurement reaches the position of the tip of the antenna is completely no problem, but considering the influence of corrosion or adhesion, the final value of the measurement range should be at least one hundred millimeters from the tip of the antenna, because some adhesive substances The layer that sticks to it cannot be counted. Fourth, it is generally necessary to add a blind zone. This is also a kind of security protection. The blind zone must be considered to set a safe distance. 5. The minimum measurement range is generally related to the antenna. As the liquid concentration is different, the generated foam will also absorb the microwave and will reflect it back, but under certain conditions, it can be measured. These problems are worth noting. You only have to pay attention to these problems in order to work accurately and better. Sixth, be proficient in the operation method, and learn more about the relevant equipment and equipment, you can pave the way for your future work.
With the comprehensive development of science and technology, radar level gauges are also improving. The latest guided wave radar level gauge is the representative of the most typical high-tech, high-tech level gauge products. In the future development, I I think the development of the level gauge will be more intelligent, and it will be more perfect and can be applied to more fields.

Deep groove ball bearings are the most widely used bearing type and are particularly versatile. They have low friction and are optimized for low noise and low vibration which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than other bearing types.
The SKF bearing catalogue lists a large range of designs, variants and sizes of deep groove ball bearings. Beyond our catalogue offering, the SKF Explorer deep groove ball bearings are customizable to offer advantages for applications with specific performance needs.
