1. Check if the power supply system is functioning properly

　　If it is found on-site that the radar level gauge changes very slowly after the level rises to the required value, the power supply system of the guided wave radar level gauge should be immediately checked for normal operation. Relevant personnel should also carefully check the power consumption of the radar level gauge during daily maintenance, and whether there is normal output after power-on. If the level change is slow or there is essentially no change, check if the equipment fuse is blown. If there is no current output, it can basically be determined that there is a problem with the instrument, and it should be replaced or repaired as appropriate. In addition, management should be strengthened during the installation and adjustment of the instrument to prevent inaccurate instrument parameters from affecting production. Relevant personnel should also strengthen daily maintenance work, with quarterly maintenance to ensure the normal operation of the radar level gauge.

　　2. Check if the communication equipment is functioning properly

　　If communication equipment malfunctions are detected, the radar detection adjustment software can be installed, the configuration data of the radar detection can be loaded, and the status of the radar detection sensor can be monitored. Key checks include whether the radar detection sensor can accurately distinguish between reflected echoes and false echoes, and whether the intensity of the reflected wave exceeds the preset standard. If the above tests are normal, other electronic components need to be checked. If it is determined that the communication module of the radar level gauge is damaged, the components should be replaced as appropriate to ensure normal communication of the radar level gauge. During daily maintenance, personnel should also strengthen the inspection of the communication status of the radar level gauge. The radar detection adjustment software can be used to connect the power cord, and the controller can be used to maintain the communication equipment of the radar level gauge.

　　3. Application Temperature

　　To ensure that the radar level gauge measures accurately, the internal temperature of the radar level gauge should be kept below 60℃. Radar level gauges are usually used to measure high-temperature media. Therefore, the housings of radar level gauges are made of materials with strong temperature resistance, so the internal temperature of the radar level gauge usually does not exceed 60℃. If the internal electronic components exceed this value, do not use cold water for cooling, as cold water will not only fail to cool but may also cause the radar level gauge to malfunction. A small amount of air can be blown into the probe head with a copper tube to scientifically reduce the internal temperature of the radar level gauge.

　　4. Inaccurate Display Value

　　Inaccurate display values are a common problem with radar level gauges. The causes of inaccurate display values may be problems with the initial saturation setting or incorrect software connection of the display control module. Relevant personnel should minimize this problem. If an invisible display value is detected, the initial settings of the radar level gauge should be checked, and the connection of the display control module software should be checked for normality. If both are normal, the output current of the radar level gauge should be checked in depth. If the output current exceeds 26 mA, it can be determined that the display control module of the radar level gauge has malfunctioned and needs to be replaced immediately. If the output current is below 3.6 mA, it can be determined that the electronic control module of the radar level gauge has malfunctioned, and the electronic control module of the radar level gauge needs to be replaced immediately.
