Hi, i have a problem with measuring level in silo using siemens S7-1200. On top of the silo there is an 0-10V radar level sensor, it works correctly, but i need more precision on my measurment.
So as you can see red line is the beam of the radar sensor. Somewhere in the middle of the beam there will be around 5V so lets say 50%. But the bottom cone of the silo can store less material than the "barrel/cylinder" part. Let's say it is 70% to 30% and im trying to write a piece of code to make the right scaling.
So far i have tried to separate the cone and the cylinder part to make two diffrent scaling functions. If it's less than 5V program will scale the gain in input in range of 0-60 so the 5V will be 30%. But i have no idea how to jump from that scaling to scale the cylinder part. Is there a way to measure only above that 5V? so then i can scale it aiming for that 70% and add both parts together? Or maybe there is another solution to that problem? I will be very thankful if someone can give me some advices on that.
