Radar in water conservancy mounting
l Basic Requirement of Radar level meter |
|
▶ There is an emission angle for antenna; There should be no any obstacle within the area where the microwave beam covered. ▶ Any shield devices should be avoided, better to learn some “false echo” knowledge; ▶ Microwave beam of radar level meter should not cross with water flow; ▶ The highest level should not be in blanking area; ▶ The radar level meter should be grounded, and take thunder prevention methods; |

Note: the highest level should not be in the blanking zone as 1 show above. |

l Radr level meter Mounting place |
|
1. Reference plane
The radar level meter should keep distance between the wall at least 200mm. |
l Weather Proof |
|
Radar level meters which are installed outdoors need to take following methods to protect the radar: 1. Tightly screw the cable glands 2. Curve the cable where near the electrical port downward. |
|
l Typical Wrong Installation |
|
1. Wrong: do not install the radar level meter above the pouring flow ; the measuring media is water surface not water flow; 2. Correct: Weather proof measurements have been taken.
|
|
l Reflector Installation |
|
If there are obstacles such as dam to affect measuring, reflectors are recommended. Or adjust mounting places; When necessary, “false echo” should be learned. |
