    Busted my Toro flow and pressure gauge, so I pulled the gauges, recalibrate them, and put them on a custom test unit I had built years ago.

    On doing some testing with the setup, noticed the flow gauge is not recording flow correctly. Did a little playing around and found out why.

    Anyone want to speculate on the principles of how their flow gauge works?

    Didn't we beat this one to death a few years back? I'll bet there's a table of flows, versus pressure and 'nozzle' size in a CRC guide.

    When I replaced a frozen gpm gauge on my Toro, I took the opportunity to calibrate the replacement.

    Don't know, but yes that is the basic principle, now explain the hydraulics of it. :)

    The living dead don't need to explain hydraulics. :)

    Let's beat it to death again. I'm curiously zombied about this.

    Actually, for the theoretically-inclined, there are some areas of interest. Your textbook illustrations might show a 'theoretical nozzle' as a simple hole in a tank, which has a wall thickness approaching zero.

    Well thanks for clearing that up for us.
