At present, there are many types of radar level gauges on the market. Radar level gauges emit extremely short microwave pulses with very low energy and are transmitted and received through the antenna system. It has the advantages of stable performance, flexible use, high reliability, and easy maintenance. So when users choose radar level gauges, what factors should they pay attention to in order to choose a suitable radar level gauge? After reading the following 5 points, you will probably understand.

1. When choosing a radar level gauge, it is best not to use a type that can handle the temperature of the medium and transmit it through the bus. This radar level gauge has more protection functions. If there is interference that causes the liquid level to be distorted, the false alarm level gauge is often kept locked, and it is very troublesome for personnel to deal with.
2. Whether to install the conduit depends on the size of the stirring paddle. If the rotating diameter of the paddle is almost equal to the diameter of the tank, the echo of the radar level gauge will be seriously disturbed. At this time, if you choose radar to measure the liquid level, it is better to use a conduit.
3. If the diameter of the rotating paddle is small, or there is a space around the storage tank for the non-rotating paddle, it is best for the radar level gauge to avoid entering and exiting the pipeline. Spin the paddle. Manhole flange. Storage tank breathers and other facilities.

4. As for the antenna of the magnetrol radar level gauges, there are various forms, including bell mouth, water drop type, flat plate type and bell mouth size. When choosing, it should be reasonably selected according to its own medium properties, such as the volatile condensation of the medium, and the water drop type should be selected.
5. Wall to the outer wall of the installation short pipe: the distance from the tank wall is 1/6 of the tank diameter, and the minimum distance is 200mm. It cannot be installed above the material inlet and cannot be installed in the center. If it is installed in the center, multiple false echoes will be generated, and interference echoes will cause signal loss. If the distance between the radar level gauge and the tank wall cannot be maintained, the medium on the tank wall will adhere and cause false echoes. False echoes should be stored when debugging the instrument.
