What are the precautions for using radar level gauges?

The radar level gauge can measure most of the dielectric constants. The power supply and output signal are more reliable through a two-core cable (ie loop circuit). It can also be measured without obstacles in noise, steam, dust, or vacuum conditions. The temperature and density changes will not affect the measurement results, so what are the precautions when using the radar level meter? 　　 1. The measurement range of the water radar level meter is calculated from the point where the beam touches the bottom of the tank, but in the measurement There are indeed some special situations at the time. The most common special situation is the concave or conical bottom of the tank. When the level is lower than this point, the measurement cannot be performed. You need to be aware. 2. According to the manufacturer of the radar level gauge, if the medium has a low dielectric constant, the bottom of the tank is visible when it is at a low level. In order to maximize the measurement accuracy, it is strongly recommended to set the zero point at the low height c. It should be determined according to the use parameters of the radar level gauge and the on-site environment. 3. Theoretically speaking, it is possible to measure the position of the antenna tip, but the influence of corrosion and adhesion should be considered. The final value of the measurement range should be at least a certain distance away from the tip of the antenna. Please refer to the operating instructions of the radar level gauge for the distance. 4. For the overfill protection of the radar level gauge, a safe distance can be defined and added to the blind zone. The minimum measurement range of the radar level gauge is related to the antenna, so the purchase of an integrated radar level timer needs to be selected according to the use environment , So that it can be more adapted to the needs of the space environment, which is of great benefit to the space. Regarding the installation of the radar level gauge, the installation instructions must be fully followed, including the diameter and minimum distance from the tank wall. Generally speaking, the radar level gauge cannot be installed above the inlet. In general, install and use the radar in the later period. Liquid level timing needs to be based on the product description, because different products have slight differences in use, and the differences in various parameters will also cause similarities and differences in later use methods.
