Coffee Sensor Flow Control Device For E61 Groupheads


The Coffee Sensor flow control device allows the user to vary the amount of water flowing through the group head with a special needle valve that goes up or down. allowing the user to profile the extractions.  Variable flow control allows for lengthy pre-infusion for more even saturation and extraction of your espresso.

The included pressure gauge will allow you to measure the pressure going through the group head during the brewing process.  It screws right into the front of the group head instead of the M6 Allen screw

The coffee sensor flow control device is compatible with most Profitec, ECM, Rocket, Lelit, Bezzera and other machines using an E61 group head.

Upgrade the look if the flow control device with a walnut knob.


Kit includes:

  • Stainless steel flow device main body;
  • Two different designed handles, made for 100% compatibility with most E61 machine on the market;
  • Group pressure gauge ( 0 -16 bar);
  • New bottom group spring to cut pre infusion;
  • Full installation and servicing kit for the flow device.

Great little add on.

Great little add-on to my ECM. Option is to keep the lower spring for pre-infusion as factory. No other real comments. Can save shots while making adjustments.

Worthwhile upgrade if you want more control

Got this since I was replacing the mushroom on my Rocket R58 anyway. Fantastic service from the Coffee Addicts team - will only by here from now on!
The flow control takes some getting used to, but installation is straightforward (remember to tape the nuts so you don't scratch them, and the upper spring and valve stay put). Lots of info online about how to use this, but be prepared for a bit of a learning curve. Also, take a stock flow rate measurement for your machine BEFORE you install, cause it will be helpful to you after installation.

Great tool

What a gret tool for better Espresso! New flavors were discovered, together with more fun pulling shots. Easy installation.

Sticky needle

Easy install and quality kit. Wonder if anyone else has noticed the pressure gauge needle isn’t very smooth. Jerks around and sometimes I need to tap the gauge window for the needle to wake up?
