    Hello all,

    We have a sealed oxygen tank. We have to measure the liquid level of the tank. There is already an existing solution where Load cells are used to measure the current weight of the tank and they subtract with the total weight of the tank and find the proportional liquid level. Four load cells are used at four ends of the tank. This makes the set up so costly.

    I came across this document (http://www.google.co.in/url?q=http:...LNJlyA&usg=AFQjCNF3YsUwW8eajkFZXxKuA0leNoHryg)
    which explains two pressure sensor can do the job.

    How practical the solution is?
    Using two pressure sensors to do the job a good idea?

    Help is much appreciated.

    Regards,
    Avinash

    It’s gonna depend on the accuracy required.

    In your situation, I would try to stay out of the product stream.

    Have you ever lined up drinking glasses with different levels of water?

    Step 1, find presure sensors that work with LOX...

    It might work, but I doubt it will be as accurate as a load cell. I'd probably stick with the load cell idea.
