As level gauges are used in an increasingly wide range of applications, radar level gauges, for example, can still provide accurate measurements even in environments with corrosive contaminants. However, in actual use, errors in measurement can occur due to various internal and external factors, thereby affecting the final results. When a fault occurs, it is the right approach to take appropriate actions promptly. Below are common faults along with their emergency handling measures. 1. One of the reasons for this issue with antenna scar radar level gauges is the use of materials with a high dielectric constant alongside materials with a low dielectric constant, as this affects the measurement results; however, measurements taken in a dry environment are not affected. The measures that users can take are: alkaline cleaning, which involves using an acidic cleaning solution to form scabs, but cleaning cannot be carried out during horizontal measurement; and using compressed air for blowing to lower the temperature of the flanges and electronic components. 2. Impact of foam: There are many types of foam, and both dry and wet foam can cause the radar reflectivity to return, having no effect on measurements; reflective neutral foam, on the other hand, absorbs and scatters radar waves. When the medium surface is thick and large, application limitations and measurement errors arise; in such cases, radar level gauges do not have an advantage and cannot be used for measurements. 3. Scarring of the probe and frequent failures: For such issues with radar level gauges, it is possible to increase the number of installation locations for the probes; however, under conditions where installation is limited, they should be used to measure the level in systems that utilize pump interlocks. The practical approach is to reduce the set value for the maximum material level by about 0.5 meters; when the material level reaches this maximum value, stop the feed pump or turn it off. 4. The main measure to address the instrument being flooded is to change the measurement waveguide of the radar level gauge. The opening remains the same as that of the original waveguide radar level gauge, and it is about 0.2 M higher than the waveguide exhaust pipe. Therefore, even if mud under harsh conditions escapes from the exhaust pipe, flooding will not occur, and interference with the vortex stirrer and the release of large amounts of steam from the detection point are avoided, reducing the likelihood of probe damage. Due to the focusing effect of the waveguide, a stronger radar signal was received, resulting in excellent measurement results. In summary, using waveguides for measurement can improve the volume conditions under which measurements are taken and enhance the performance of instruments, thus holding significant practical value. For the various faults of radar level gauges, users need to take corresponding measures to resolve them more effectively.
