Reader Tip: Using a Flow Meter for Water Volumes

Thanks to HBF Reader Robert for this tip!
Robert uses this flow meter to measure brew day water.  He says it's worked well for him.

A couple things to keep in mind...
  • This particular model only tracks to the nearest liter.
  • This is rated up to 140 degrees F.  Higher temperatures may leach undesirables into your water.  You'll need to pre-measure warmer water additions like strike and sparge water.
  • This ships directly from Asia, so it takes a while to arrive.

Robert is using the Flowmeter2 found here.  It's currently selling for $18.90.  I'm not sure what shipping costs.

  1. So... If it's only rated to 140, it's useful for mash and sparge water... How, exactly?

    I'll stick to the graduated spoon approach. :)

    1. You know, you're making a good point. :)

    2. On second thought, I think it would still work well for strike and sparge water. Thinking through my own process. I measure these volumes when the water is cool.

    3. I measure my water when it's cool too. I guess it all depends on your setup and process. Would be kind of neat to find inexpensive ones that were rated higher though. If you're a fly sparger you could use two meters to help dial in the flow rates.

      Also you could use this post-chiller to measure wort going into the fermentors.

    4. Well, assuming it doesn't clog on the way to the fermentor... the bigger 1/2" one for $1 more might be better for that.

    5. I use this to measure cool water into my HLT, which I then heat up and use for mashing/sparging. This works fine so long as with your brewing setup you're measuring cool water into your HLT, and not measuring hot water from another container into your HLT or measuring hot water from your HLT into your mash tun.
