    Default Measuring sap volume

    Does someone have a link for a flowmeter well suited to maple. It would need to measure high volume - thousands of gallons at a time - but at low pressures. Ideally it could measure on a gravity dump line without restricting the flow too much.

    Have you looked into ultra sonic flow meters? I am a little surprised the maple industry has not gone that route already because most flow meters sold in this industry are not food grade rated. They would not restrict the pipe at all

    Google gpi flowmeters (great plains industries). We've had one for eight years now. It is accurate, never had to change the batteries, and has recorded 2.5 million gallons of sap

    I second this, incredibly accurate meters. pricey, but worth it if you're buying sap.have tried a bunch of others, these work the best, going on 6 years now.
    4000 taps on vacuum, just trying to get a little better every year.

    Thanks for this tip. This is one I found in a quick search. The lowest rate is 3 gpm (or 180 gph). I sometimes drop below this on my RO with late season sap or when I'm squeezing it tighter. Do you put this on the sap line to your RO or somewhere else in the process? Actually, now that I think about it, I just started recirculating instead of doing a separate pass first. I'm not sure where I would put it now., but I'd love to have amore accurate way of measuring sap.

    The only practical use for a flow meter would seem to be if you're selling/buying sap, particularly if you're drawing off from an enclosed tank where measuring volume is a challenge.
