In addition to the three debugging methods for radar level gauges introduced earlier, their installation can also be evaluated through basic inspections after installation. Next, we will introduce the basic descriptions of on-site inspection, connection, and power-on. First, a site inspection is carried out to determine whether the actual operating conditions at the site are suitable for using radar level gauge models, and to verify that the installation location is correct and that the installation environment does not have any adverse effect on the instrument’s performance, thereby preventing malfunctions that could affect its use. In addition to the radar level gauge, which requires on-site inspection, this task also needs to be carried out for other instruments as well; it is a relatively basic requirement. Secondly, perform a power-on check. Because after power is applied, it is possible to observe whether the radar level gauge proceeds through the normal startup procedure step by step and displays properly. Moreover, many unexpected occurrences happen because of power issues; or in some cases, there’s no power at all, so the instruments fail to function properly. If conditions at the site permit, it is also possible to observe whether the level gauge exhibits linear variation and other parameters by monitoring the material inflow and outflow. Immediately afterwards, a connection check is performed. This overlaps with on-site inspections, in that by connecting the appropriate software, it is possible to observe the linearity of the level gauge. Generally speaking, instruments with buttons can also achieve this function. Users can also use specialized instruments to perform connection checks, thereby determining whether the radar level gauge is functioning properly. Apart from the methods mentioned above, there are many other ways to test the radar level gauge after installation, ensuring that the instrument functions properly without affecting the workflow.
