    For $50 I don't think you will have much choice.

    Try getting some sort of propeller into the water stream and count the blades going by a Hall effect sensor.

    Omega Engineering has some paddle wheel style with a pulse output but are well over $50.

    Try e-bay as well.

    If the delivery stream doesn't have to be under pressure, you can build a weir dam in a piece of rain gutter with a triangular slot in it. Measure the height of water as it builds up against the weir. More height means more flow.

    Good luck.

    It's not $50, but it's under $100: webcat.ryanherco.com/products/490/120/210/490120210.cfm. And it would interface nicely with a BASIC Stamp.

    What's the diameter of the pipe and what kind of flow do you expect?

    There would be an associated water pressure with a certain flow in a certain pipe.
    Do you just want to know set points? Could just use a water pressure switch (fairly cheap)....then set it for the pressure you're interested in.

    I bought two of these and I took one apart and it has a reed switch in it

    Found this by Googling. www.allergybegone.com/flowpro-fpdm-200-digital-flow-meter.html

    I am going to use a Parallax Melexis 90217 sensor to count the RPM's and chage it GPM

    I will have to order some of these to play with

    http://www.parallax.com/detail.asp?product_id=605-00005

    It has a nice wheel with a magnet and runs very freely well worth the $27.00 for it

    Thank You For finding this item for me

    Flow meters are notoriously expensive. You can try Great Plains Industries, they make fantastic units, but there is a great variation in prices. The one I just used for a client project was all stainless steel and cost almost $1k!!!

    Thank you for posting this. They have the exact sensor I wanted for a project a couple months ago. -Bookmarked-
