I'm using this ultrasonic sensor with my arduino build to tell my unit when to fire the heating element (safe volume level) and when to turn off the heating element if I'm in danger of a boil over. Can't wait to say goodbye to the chance of a boil over while I'm not watching the kettle. Gotta love automation!
That is way cool. What is the state the sensor uses to determine impending boil-over?

It's an if statement based on the distance the sensor pings. If the distance it sees to the liquid level is short enough, then it turns off the little output pin to the heating element.

Can you tell us what type of ultrasonic sensor you're using?

same one that i setup. it worked over a keg of water at ambient temperature but i wonder how good it will be when mounted over a steamy hlt or aimed at a foamy potential boilover.

Stream does not (or should not) be seen by the sensor. I am more worried about debugging the sensor for the temp change and the nonreflective surface of the foam. Haven't gotten it yet...

It's just that i've done a very modest bit of research on this and i found even with far more sophisticated sensors there is a degree of tuning required based on the environment in question. That's not to say this approach can't work.

How about this thread be used to motivate us to be he first to find an actual practical use for this HC-SR04 module. Winner can prove that the module measures accurately enough to automatically deliver a specified volume of strike water to a mash tun. This means the system has to stop the HLT being filled at the desired volume, hit the desired strike temp and subsequently stop the pump to the mash tun when enough strike water has been transferred.

In case any one thinks i have a head start i still don't have power/water in my brewery

What about a liquid level sensor

Pretty slick, but datasheet specs only rate it to 150F, so would probably fail in brewing conditions.

Last I read, they are working on a higher temp one, but no idea when that will happen.
