At present, there is a better choice on the market, that is, to bring a radar hydraulic gauge that is not particularly known. This kind of liquid level measurement method belongs to the instrument measurement of non-contact water. Therefore, the operator does not need to enter the chemical tank directly, and can carry out maintenance and installation work on the tank outside. In the measurement of liquid level, the microwave technology is mainly used, Therefore, it has the advantages of higher reliability and simple installation. The most important thing is that it does not need any maintenance work. In addition, it also has the following advantages:

1. Because this measurement method does not need any contact with the measured medium, it will not be affected by any pressure, temperature and other parameters;

2. It has the function of automatic fault diagnosis and direct fault alarm, which can effectively control the parameters remotely, monitor and modify them, so as to make the maintenance personnel safer in work;

3. It is also very important to select the radar liquid level gauge. We can select it according to the main conditions of the process, and also consider the measurement accuracy properly, so as to ensure the selection of an effective and appropriate radar liquid level gauge.
