E61 M6 Y adapter for temperature & flow gauges?

#1: Post by **BenS** » January 11th, 2022, 7:03 pm

Hi There,

Sorry if this has been discussed (I might've used incorrect search terms) but can you get a Y adapter to screw into the E61 port to allow temp and flow pressure gauges at the same time?

Would love a flow control kit but not sure I could live without the temp gauge - or is there a technical reason why this wouldn't be possible?

Cheers, Ben

Or as an alternative, could something like this be adapted to the port - or is it not as simple as that?

They have various versions, I guess the 0-16bar versions would be best for flow control - yes?

Cheers

The smart espresso profiler has a y adapter. So it's possible.

You'll need to verify if both ports are standard sizes though.

Awesome, have asked them. Thanks for your help.

Pressure can go essentially anywhere, but temperature placement is critical as you likely want it as far down the hole as possible so it picks up the flowing water.

Yes, and that's why the Taylor thermometer with the probe that is in the water path works so well.The pictured gauge will likely measure the temperature of the group head brass and not the flowing water. An adapter that allows the thermalprobe to enter the water path with a wye connector off to the side for pressure reading should work well to measure both pressure and temperature.

I have the Coffee Sensor unit, does that enter the water path as well?

I don't know, but I would imagine it does not. If the part that screws into the e61 port looks like the one on the earlier posted picture, then it does not. The e61 thermometer I use on my Quickmill machine has a probe that does protrude into the water channel in the grouphead "nose."

Seems like the profiler adapter would work but you'd need an longer probe in the thermometer to reach into the water path... maybe like this one?

Then the pressure gauge would hang off the adapter's side port. Of course that's assuming that the threads all match up!

Yes, exactly like that, but to connect a pressure gauge to that you'd need a "wye" connection. The thermometer probe would get down into the brew water flow and the pressure gauge would be off to the side. The pressure gauge doesn't need to be in the path of water flow to the brew chamber, since it only needs to measure the water pressure in the brew chamber.
