Thread: measuring flow rates of airborne straw

    We would like to pace other flow rates to that of
    straw being blown/sucked in a closed 6-10" pipe.
    The problem is that the straw is so light and of
    such low moisture (around 8%) that it is difficult
    to see what technology is best suited for the task.
    Some sort of light obstruction system might work, but
    these do not seem to be commercially available.

    Your help is appreciated.

    I have been involved in the metering of straw.
    It is not easy.
    It can be done when the straw is fed into the
    blow line by volume or by weight.
    By weight is not so easy because of the low
    density.
    You can also measure the pressure drop in the
    pneumatic conveying line.
    I would need more details to give better
    information.

    Kind regards,


    Bart
