In level measurement, liquid level measurement, material level measurement and boundary level measurement also have different characteristics due to the different materials measured. These different level measurements have different performance in the actual working conditions and have different requirements for the level measurement instruments. Therefore, it is important to understand the properties of different level measurement so that the selected level measurement instrument can be matched with the application conditions when selecting the level measurement instrument.

　　Level measurement, liquid level measurement and boundary level measurement each have their own characteristics. Generally speaking, in practical applications, their different characteristics are mainly manifested in the following aspects:

I. Characteristics of material level measurement

　　In the material level measurement, influenced by the characteristics of the material, often has the following characteristics:

　　1、When in and out of the material, the material will rub or impact with the measuring element, and also hang material on the measuring element.

　　2、When entering and leaving the material, there will be stagnation area, bridging and accumulation of material on the silo wall.

　　3, in the natural accumulation, the material surface will be a certain rest angle, rest angle with the material particle size, specific gravity, surface fluidity and different, and by adding or discharging, adding the way, adding (discharging) material mouth position, etc. greatly affected.

Second, the characteristics of liquid level measurement

　　Different liquid properties, liquid level measurement also has different characteristics:

　　1、Large storage tanks will have uneven temperature and density in various places in the storage tank.

　　2、In float gauge liquid level measurement, vacuum, high pressure, high temperature, or high temperature and high pressure exist at the same time.

　　3、In liquid level measurement, the various corrosive media measured have different corrosiveness.

　　4、In the process, the liquid level will fluctuate, boil, foam, contain suspended particles, contain bubbles, high viscosity and other different working conditions.

Third, the characteristics of the boundary level measurement

　　In the measurement of liquid-liquid and liquid-solid phase interface position, sometimes the interface will not be obvious and there is a turbidity layer.

　　The above three different level measurement have different characteristics and performance, and have different requirements for level measurement instruments.
