hot water flow sensor

[jessey]

Hi Darrel,

The code I posted in the last post is not correct, I caught it after I posted it. The new revised code here has been tested and is working good.

I'm now thinking of putting the DS1820 on the bottom of the inside of the tank directly in the path of the incoming cold water (epoxyed into a SS tube) so my code will catch the sudden temperature change.

I was also thinking of placing a mechanical reset-able high temperature limit switch on the side of the tank for added insurance. I can use the same one that was on my old hot water tank.

Thanks
jessey
