What causes this phenomenon in the Cologne guided wave radar?
Thread Content
I am using a BM100 guided-wave radar to measure the material level. Recently, the output remained constant during the discharge process, but it suddenly dropped in pulses toward the end – what could be the reason?
Is it a liquid material, a solid material, or a powder?

The BM100 guided wave radar is no longer in production – it’s too old, and you’re still using it. I have the 1300 series here, and it’s guaranteed to work without any problems. During the discharge process, the output remains constant; at the end of it, there is a sudden pulse-like drop in value. The threshold voltage can be adjusted, as well as the amplification factor. If dry powder is being measured, it might be damp – it’s raining where you are, right? Reach out to me if you need anything; post a message.
If measuring solids or powders, no guided-wave radar from any manufacturer will work; I recommend choosing an intelligent radar with a flared horn.
