As a new type of measuring instrument in the level gauge industry, radar level gauges are being used more and more widely. To determine whether a radar level gauge is functioning properly, it is necessary to consider certain specific characteristics of such gauges. Below we explain how to assess whether a radar level gauge is working correctly. 1. First, check the installation and operation of the radar level gauge on site to determine whether it is installed properly, meets the installation requirements, and whether there are high-power motors in the vicinity that could generate electromagnetic interference and affect the operation of the radar level gauge. To resolve the above issues with radar level gauges, follow the installation instructions provided in the product manual for radar level gauges strictly. Secondly, electromagnetic interference requires a ground wire to be connected to the radar level gauge. 2. Perform a power-on check on the radar level gauge, as by powering it on, it is possible to see whether the gauge proceeds through its normal startup sequence and displays properly. Moreover, many accidents occur due to power supply issues, or the instrument simply won’t function properly if there is no power supply at all. 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. Secondly, a connection check is carried out; this overlaps with the on-site inspection, as 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 conduct connection checks in order to determine whether the radar level gauge is operating properly. As a professional manufacturer of radar level gauges, Xi’an Dinghua Electronics Co., Ltd. provides customers on-site with useful guidance for the installation of radar level gauges, as well as on-site commissioning services.
