Hudson bay distillers Posted November 16, 2017 Share Posted November 16, 2017 hello i was wondering if there anyone with experience useing bulk milk coolers could explain to me how to interpret the numbers on the dipstick . the tank is 425 gallons and the dipstick goes up by small increments of 4 till 32 then starts again . as in 2,4,6,8 and so on till it reaches 32 , then it marks one and then starts over again and marks 2 ect ect till the top where it ends on 27 . the tank is a john wood insulated tank with a refrigeration unit attached .

BeeJuice Distillery Posted November 16, 2017 Share Posted November 16, 2017 They are all different depending on the tank size. Each number is 32nd's of an inch of tank depth. You will need the chart for the tank to convert the dipstick reading 1 Link to comment Share on other sites More sharing options...
Silk City Distillers Posted November 16, 2017 Share Posted November 16, 2017 The dairy would have had a calibration chart provided by a third party to go along with that specific tank. Link to comment Share on other sites More sharing options...
SlickFloss Posted November 16, 2017 Share Posted November 16, 2017 We had same issues with repurposing similar tanks by same brand. I emailed tankinfo@johnwood.com and we figured out a calibration sheet for us to use..... Link to comment Share on other sites More sharing options...

Silk City Distillers Posted November 16, 2017 Share Posted November 16, 2017 You will not find a chart - you need to make it yourself. Do it by weight and interpolate the curve. Link to comment Share on other sites More sharing options...

Hudson bay distillers Posted November 16, 2017 Author Share Posted November 16, 2017 so now im curious would that chart still work seeing as milk weighs different than mash and mash weighs different depending on its grain content . cuz i see the chart is calibrated on milk weighing 8 lbs per gallon .

Silk City Distillers Posted November 16, 2017 Share Posted November 16, 2017 Don’t over think it, sure the milk calibration is complicated, but keep in mind it’s because it’s a legal-for-trade situation. Milk is roughly 1.03, so it’s not far off. Link to comment Share on other sites More sharing options...
