As the level of automation continues to improve, radar level meters are used in an increasingly wide range of applications. In the use of the process, radar level meters will also appear in a large or small problem. The usual solution to these problems is to identify the cause of the fault and solve the problem according to the cause. In fact, there is another way of thinking, which is to solve the problem directly.
First, disconnect the power supply and restart the equipment. The installation environment of the radar level meter is complex and variable, there are spherical tanks, there are vertical tanks; there are small tanks, there are large tanks; there are indoor installations, there are outdoor installations. If we all adopt the method of unloading to find the cause, it undoubtedly increases the difficulty. Therefore, when there is a problem with the radar level meter, you may wish to disconnect the power supply, restart the equipment and see if the level meter runs normally after restarting.
Secondly, by commissioning software debugging. Radar level meters often have problems with data jumping, data staying the same, data deviating too much or too little from the actual value, and so on. Sometimes these problems are caused by errors in the range determination, sometimes by false echoes. These problems can be solved by re-commissioning.
Thirdly, replace the installation position. If after debugging, the fault still cannot be eliminated, we have to observe the installation position of the radar level meter, to see if it is too close to the inlet port, to see if the radar level meter is installed above the inlet port of the conical tank, and so on. If the installation position is found to be unreasonable, the problem can be solved by replacing the installation position.
Finally, if the above methods do not solve the problem, the final step is to dismantle the radar level meter and wipe the antenna. Radar level meters do not measure correctly, sometimes because there is too much adhesion on the antenna, which affects the measurement.
