I have used ultrasonic for many years for measuring levels of various materials. Most are not affected by dust or turbulance. I would think that foam would not be an issue but if your using it to measure level in HLT or MLT, foam shouldnt really be an issue. Im in the process of puting mine together with a Micrologix 1500 PLC and plan on using ultrasonic for the HLT. Plus this is just my 2.

Nice. Micrologix! I know a professor who had one that wanted me to program it and build him an automated brewery. Unfortunately, at the time I knew nothing about that ladder logic programming language. Would love to have one of my own to play with.

I highly doubt the stream over 12" above the liquid is 150F in an atmospheric pressure.

They are just very expensive.

Wondering if anyone has any experience with a proximity sensor strapped to siteglass?

Sometimes I think this get over engineered when they can be very simple. I know you said no float switch but it doesn't need to be attached to the pot. I attached it to my sparge arm so the whole thing comes out in one piece and is not part of the pot.

Slick setup, with simple elegance! I'm guessing the whole assembly is vertically adjustable for different batch sizes? Do you have a source/price you can share?

Still interested in a way to set sparge volume, what is the range of sensing with that float?

Thanks, Dale

eBay, search "Stainless Float Switch". There's plenty of different lengths, mounting options. I have a few of them for my rig, they were about $8 each.

Interesting ideas here! For those of you using pressure sensors (like with the Brewtroller), do you use this on a MLT? If so, wouldn't the suction from the pump during recirculation lead to inaccuracies during recirculation?

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

Has anyone done it yet? I might embark on this mission as my first foray into Arduino programming. I'd hate to just replicate something that's already been done.
