Thread: Bin Level Measurement

  1. Bin Level Measurement

    Hello
    What kind of level switches are best for fixing in the bin having ferro alloys. The level switch which we are using are capacitive type and the biggest problem we face is with the minimum level switch as it gets damaged during filling the bin as the material falling over it damages it. We tried to fix some kind of canopy/shed over it but still it does not work perfectly. For high level switch , we never faced such problem. So i am looking for suitable level switch for the bins.
    I have seen some level swich which works on radio activity principle but it has safety concern. Putting weighing system on the bin itself is good idea but its very costly and when we have lot of such bins , it is not economic.
    Any other idea if some one is using please reply...and share...

    2) For continuous measurement of the bin the level transmitters are micro pilot ultrosonic level sensors . The minimum level signal can be generated by comparing the actual level of the bin with certain value. But the design of level measurement is also not correct. Generally the bin should have filling window at the center so that the material inside bin make a piramid patern. In our case the opening for filling the bin is on one side of the bin so the material patern inside bin when filled is slanting so real level is very difficult to measure. Is there any other level measurement which can work in our system. or any suggestion ...

  2. Acoustic device for volume calculations

    You posted this question quite a while ago, so not sure if you ever found solutions to your problems. I am not as familiar with the switching. But for continuous level, we do have a product that uses acoustic technology that can view the entire contents and give you good picture of the surface of the solids in your vessel. Depends on your vessel size as you may need multiple devices for larger vessels. Search for Emerson's Rosemount 5708 for info if you are interested. Otherwise, hope you had some luck.
    Thanks,
