Always get the largest enclosure you can practically fit on your rig! Much better to have unused space (which you can maybe use later) than too little - word!
Who is your supplier if you don't mind me asking? For the volume sensors.Working on sourcing some plug and play sensors for liquid level (volume) measurement. Taken a couple of iterations but I think these are going to fit the bill.
Testing these on my personal rig. First added a tri-clamp solder-on flange courtesy of BrewHardware.com.

Bottom mounted on this kettle but side mount could be accomplished too - anything below the sensor can’t be measured of course.

Inside view. Please ignore the stray tooling marks... had an issue trying to cut out the previous soldered-on coupling! Note these will be very easy to clean after - just a little sponge to draw out the extra liquid sitting inside the flange.

Initial performance seems good. A bit of upward creep when heating, but nothing that will intro any significant error. Stay tuned!!
So I dont know if anyone else has experienced this yet but I'm experiencing voltage spikes from the 240v coils on my element contactors or the contacts themselves which SOMETIMES cause my RTD temp reading to drop out momentarily, These happen more often when deactivating a set of contactors (I have multiple groups of contactors tied together to control up to 4 elements for each kettle and the rims contactor). After googling my symptoms I have found its a fairly common issue thats usually cured with Snubber capacitors for arch quench or MOV placed across the contacts absorb the voltage spike and extend the life of the relay contacts.. I have ordered some and my fingers are crossed they will resolve the issue. I have also addressed the grounding of everything to prevent ground loops which can also cause this interference. a couple times the effect was bad enough to cause the arduino to lose connection with brucontrol and other times theres no effect at all which is strange. when It does happen I can see a faint flicker of all the leds on the arduino relay board which controls the contacts for the main contactor coils.
Turning the blichmann Riptide pump on and off has even caused this problem though through a different isolated relay board, though not as often during testing. I have tried both high level and low level triggering on the relay boards and it makes no difference. I have also tried powering everything off of the usb port and 5v with a 5v relay board as well as powering it off of the 12v meanwell din rail supply and a 12v relay board
Some people have reported other devices like fans causing this as well so I felt it something worth sharing if anyone comes across this issue.
Great! ThanksThese are built by a Chinese supplier doing custom builds for us. We will stock these and offer them via our website in the next two weeks.

What are the overall dimensions of the sensor and the triclamp portion? How much space would one need under their Vessel to use it?
Im not sure about the riptide but it does happen when My element contactors turn on and off even when the breakers are all off that they feed so I think it may be the coil itself. I picked up some of theseThis does seem to be a problem that has popped up on a few builds. I haven’t experienced it personally but will collaborate with anyone to help figure out he source.
Does this happen when the downstream device (eg pump) is not connected? In the case of the riptide, does it happen with the switch on the pump turned off but power supplied to it via the relay?
Hi @BrunDog-Hi HBT,
Many of us implement Voltage/Current meters as a matter of course to monitor AC line voltage and current use. We’ve received several inquiries about voltage/amps measurements, and we have always known it relatively easy to do with a custom circuit, but due to the gentle prodding of @GParkins, I put some energy to identifying an off-the-shelf sensor. For current anyway... voltage is next.
. . .
Now my current will be constantly displayed on my brewing screen - psyched! As I said, voltage is next. Then we can compute power usage, cost, etc. from that data as desired!
Ok so I made some progress... I purchased and add these https://www.auberins.com/index.php?main_page=product_info&products_id=238This does seem to be a problem that has popped up on a few builds. I haven’t experienced it personally but will collaborate with anyone to help figure out he source.

I found this one on ebay, but I am at least a little bit dubious given that the list price for this sensor is a bit more than $100. I bought it and will report back once I get my panel wired up.CR Magnetics makes some but I find them too pricey. This is about the best I have found given the price, though it is still more than I would like: Loulensy AC Voltage Transducer Voltage Sensor Transmitter Transformer Input 0-250V AC Output 0-5V DC https://www.amazon.com/dp/B01ANV0RFI/?tag=skimlinks_replacement-20
How exactly? Its dc and im not sure I have anything to measure that small of a dc load?Please measure the current required to switch the SSRs.
Would the breakout board need a resistor for the onewire temp sensor? Could I put multiple sensors on the board?

I was wondering if I could get some help from the scripting gods.. Here is what I have:
Chiller
Temp sensor (Gylcol Reserve Temp)
Valve (Recirc Loop)
Pump (Glycol Pump)
Hysterisis (Glycol Temp Setting)-using compressor
FV1
FV1 Temp sensor (FV1 Beer Temp)
FV1 Hysterisis (FV1 Set Point)-using valve
FV2
FV2 Temp sensor (FV2 Beer Temp)
FV2 Hysterisis (FV2 Set Point)-using valve
(denote actual names)
So basically you would have a loop of using the hysteresis for chiller to maintain the glycol reserve temp. Which means the pump (Glycol Pump) and the valve (Recirc Loop) will need to be on/open.
Next you have FV1 and FV2, they each have independent hysteresis using a valve for each. Using the same pump.
So the process flow would go something like this...
Maintain Hysterisis (Glycol Temp Setting) with pump, Valve (Recirc Loop).
if FV's call for cooling, close Valve (Recirc Loop), maintain FV Hysterisis (FV Set Point). If at temp or below FV Hysterisis (FV Set Point) turns off and Valve (Recirc Loop) opens.
Basically I want the pump on at all times. Then I want BC to pick what valve to open based on temperature needed. If the fermenters are happy the Valve (Recirc Loop), opens to keep the loops cool, and stop stratification in the reserve.
I probably didn't explain it right...
Ya I am confused. Say what types of devices each are with their names and functions.
@augiedoggy I'm seeing similar behavior on both of my enclosures. On the brewstand controller, I occasionally lose WiFi connectivity when a pump fires, especially when an element is on. I also see temp spikes (PT100s) I need to reset the Mega when that happens. The effect of the reset is that configured valves start going back to their default state, but the pumps keep running. Fluid almost always goes places I don't want it to when that happens.
On the ferm controller, I see temp spikes (1-wire sensors) that appear to be correlated to either the circulation pump or the chamber fans turning on. There, the effect is that the spike goes across all temp sensors, and triggers the glycol chiller to cycle on.
@BrunDog sent me to a link where a guy successfully used ferrite chokes to suppress his symptoms.
Maybe you and I should compare notes and see if we can find a common thread to pull on.
I actually saw this on my new glycol controller. But it’s when a relay shuts off. THe controller loses connection until reset.
I think you want the scrubber across the coil:@Die_Beerery I'm not 100% sure on the timing of my "events." I may be spiking during shutoff cycles. I'm going to get a handful of the Auber snubbers that @augiedoggy suggested, and hook them across the COM/NC terminals of the relays for the pumps, fans, and the glycol chiller compressor. Here's how I'm going to do it:

putting arcoss the relay contacts of the relay that powers my coils actually worked I assumed I damaged the relay board with them though when things started acting up but now I wonder if it was the poor ground connection.I think you want the scrubber across the coil:
