Radar level gauges and guided wave level gauges

Thread Content

　The antenna of the radar sensor emits electromagnetic wave signals in the form of beams; the emitted waves are reflected by the surface of the material being measured, and the reflected echo signals are once again received by the antenna. 　　Each point in the transmitted and reflected beams is acquired using ultrasonic sampling. After being processed by the intelligent processor, the signal determines the distance between the medium and the probe, which is then sent to the terminal display for display, alarm generation, operation, and more. 　　Feature: The biggest advantage of radar level gauges is their excellent performance under harsh conditions. It can measure both toxic and corrosive media, as well as solid, liquid, powdery, or slurry-form media. In terms of measurement, it has the following characteristics: 1. Continuous and accurate measurement. The probe of the radar level gauge does not come into contact with the surface of the medium; it is a non-contact measurement method that enables accurate and rapid measurement of different types of media. The probe is hardly affected by temperature, pressure, gases, etc. (the impact is only 0.018% at 500°C and 0.8% at 50 bar). 　　2. It has the function of suppressing interference echoes.
3. It is accurate, safe, and energy-saving.
The materials used in radar level gauges are highly stable both chemically and mechanically, and they can be recycled, making them extremely environmentally friendly. 　　4. No maintenance required and high reliability 　Microwaves are hardly affected by interference, and since they do not come into direct contact with the medium being measured, they can be used in a wide range of applications, such as vacuum measurement, level measurement, or inventory level detection. Thanks to the use of advanced materials, it is resistant to highly complex chemical and physical conditions, and it can provide accurate, reliable, and long-term stable analog or digital level signals. 　　5. Easy to maintain and simple to operate. The radar level gauge features fault alarm and self-diagnosis functions. Faults are analyzed based on the error codes indicated by the operation display module; the faults are identified promptly and resolved, thereby making maintenance and correction more convenient and accurate and ensuring the proper operation of the instruments. 　　6. Wide range of applications – it can measure almost all types of media. In terms of the shape of the tank, radar level gauges can be used to measure the level in spherical tanks, horizontal tanks, cylindrical tanks, and conical cylinders ； In terms of tank functions, it is possible to measure the liquid level in storage tanks, buffer tanks, microwave tubes, and bypass pipes ； In terms of the medium to be measured, liquids, particles, slurries, etc., can be measured. 　　Summary: In general, radar level gauges have a wide range of applications and utilize a non-contact measurement method. It features high-quality materials and a low failure rate.
