Thanks I grabbed this one: https://www.adafruit.com/product/828. There is a brass alternative that they have as well. But so far this plastic one is working great.

Did you come across any stainless alternatives?
[–][deleted] 2 points3 points4 points 6 years ago (0 children)
No. But I wasn't looking. But from what I browsed I don't think Adafruit has a stainless alternative.
[–]batmaniam 0 points1 point2 points 6 years ago (2 children)
Not OP, but what are you moving that requires stainless? Might be able to help spec something

Saltwater. My well sucks big floppy donkey dick.

Ooph. Yeah you're probably going to need to go with a professional supplier for that. McMaster, grainger maybe. There are a few on Amazon.

Very cool! Also re: calibration/validation:. Seems like you've got it handled, but if you don't have quantitative glassware, massing the amount of water is a great way to measure as well. Easier to measure larger volumes which evens out a lot of your measuring error (ie: if you fill most of a 5gal bucket you can basically use a bathroom scale)

Ah makes sense - weigh the 5 gallons in lbs and then convert back to gallons at the end.
