    Dear all,

    Your discussion are VERY interesting for me.

    I need help/idea "how to detect dead waterline pipes/part of pipes" in building's. Especially in large business buildings, as hospitals, shopping malls etc.

    Ultrasonic flow meter was my idea, too. But this stuff are so expensive, that it is hurt.

    Tank you ,

    Kind regards,

    Vojislav

    What exactly constitutes a dead water pipe? If there is no water flowing in that pipe when all taps are open?

    From http://www.globalw.com/products/FM500.html

    To measure phase shift(Doppler) @40kHz and/or speed of sound would require somewhat advanced PLL, ADC, and processor power.

    Considering the breadth and depth of knowledge needed to create a non-contact fluid speed sensor is a project that even experienced designers would find a tad daunting. Parts cost alone would be a good fraction of the cost of a commercial unit for a one off prototype, which may not work in a fully reliable/accurate way.
