The radar level gauge has the advantages of low maintenance, high performance, high precision, high reliability and long service life. When measuring the liquid level of a container, it is affected by many external conditions such as the shape, size, diameter, and material of the container, and is also affected by the physical and chemical properties of the medium such as steam, foam, and corrosive volatility.
　　　　 First, the installation requirements and selection of radar level gauge in general containers:
　　　　 If it is in an open pool, water tank, or natural waters, it has no effect on the radar used. All three can be used. On a closed container, the guided wave radar level gauge can be installed on the DN40 socket. The low frequency flare radar and the high frequency flare can be installed on the DN50 socket, provided that there is no agitation, foam, steam, pumping. Vacuum, if these conditions, the high frequency radar should be installed with a DN100 flange, and the low frequency radar should be installed with a DN150 flange.
　　　　 Second, the radar level gauge in the selection of corrosive liquids and precautions:
　　　　 The flange and cable of the guided wave radar level gauge are 304ss by default. 316L material can be used for general corrosive liquids. Teflon can be used for strong corrosive liquids such as hydrochloric acid and nitric acid.
　　　　 The flange and bell mouth of the low-frequency flare radar are 304ss by default. When encountering general corrosive liquid, 316L material can be used. When encountering strong corrosive liquid such as hydrochloric acid or nitric acid, it is necessary to spray PTFE.
　　　　 The flange and bell mouth of the high-frequency flare radar are 304ss by default. When it encounters general corrosive liquid, it can be made of 316L material. When encountering strong corrosive liquid such as hydrochloric acid and nitric acid, it is necessary to spray PTFE.
　　　　 In the case of strong corrosive liquids such as hydrochloric acid and nitric acid, it is more suitable for low frequency rod radar and high frequency rod radar. Both radars are designed for use in highly corrosive environments. It should be noted that the blind spot of the low-frequency rod radar is relatively large, 0.5-0.7 meters, which is not suitable for small jars.
　　　　 Third, the radar level gauge in the selection of foam liquid and precautions:
　　　　 Foams with a surface of no more than 2 cm have little effect on the measurement. For foams over 2 cm, the thickness of the foam and the size of the foam should be noted.
　　　　 In foams measuring more than 2 cm, fine foams are less likely to penetrate by radar electromagnetic waves than large foams. At the same thickness, the thicker the foam, the less likely it is to penetrate.
　　　　 In this case, the low frequency flare radar is more suitable than the high frequency flare radar. If it is a non-adhesive foam, then the guided wave radar level gauge can easily penetrate the foam and correctly measure the liquid level below the foam.
　　　　 Fourth, the radar level gauge in the steam environment selection and precautions:
　　　　 In the presence of steam, there is not much impact on the guided radar. The impact on the low-frequency flare radar is small, and it also has a small impact on the high-frequency flare radar.
