1. For liquid medium, meter should be vertical with sensor toward downside.

2. For solid medium, ultrasonic or radar meter should be toward discharge port in bottom.  

3. The distance between beam center of ultrasonic or radar and tank wall should be longer than beam radius of minimum (liquid) level calculate by beam angle and measuring range. 

4. Beam path of ultrasonic or radar should avoid injection range of feeding flow.

5. Beam path of ultrasonic or radar should avoid blender or other obstacle.

6. The installation of ultrasonic or radar (liquid) level meter should also meet requirement of its manufacturer.
