Brewing Inventions Not Yet Made

I'll soon have one. Does it automatically calibrate the Spercific Gravity reading for temperature?

 

I contacted them and was very disapointed to learn that the Tilts do NOT make corrections. I can't understand why they didn't even bother including the corrections. Thus, many using them are not obtaining proper readings. They wrote back and said:

"Due to the polycarbonate housing of the the Tilt, no correction is needed from approximately 38°F to 98°F. Temperatures above 98°F result in an decrease of SG of about 1 point per 10°F. i.e. water at around 160°F will read 0.994."

I don't understand how the housing itself can prevent changes to the Specific Gravity. I find that hard to believe.

 

I plan to use them for both the mash and fermentation. I needed a way to measure the temperature in the mash wirelessly (in this part I'm not concerned about the SG), and I also need to measure the SG of the fermentation of the lagers I make, which can drop to close to freezing. Thus I will still need to make corrections to the readings below 38°F.

For making ales, the temperature could go up to 80°F for certain Belgian styles. Although they say the housing magically adjusts for temperature correction up to 98°F, I find that hard to believe. Why should that affect the degree of flotation of the device?

I'm not familiar with Coriolis meters. How do they work and what do they measure? Do they only work when a flow is involved?
