Description:

Flow Control Device for E61 group heads. (For wooden handle see Coffee Sensor E61 Flow Control walnut handle or below)

If you have to replace your e61 mushroom, due to mineral build-up and chrome flaking off - then this would be an ideal upgrade, as the mushroom is made from stainless steel, so the lime won't stick and there is no chrome to flake.

This kit allows you, to pressure profile by adjusting the pressure of water flowing through the coffee. The flow can be controlled due to its special needle valve, which allows for lengthy pre-infusion for even more saturation and extraction of your espresso drinks.

As the flow is modified, the pressure is shown on the gauge.

All the metal parts are stainless steel so you won't need to ever replace the mushroom, the chrome-plated brass mushroom starts to corrode after 3 years.

Product features:
  1. Long pre-infusion - adjust the length of pre-infusion 
  2. Control flow, lower pressure for 100% arabica, single origin, or light roast.
  3. Lever machine extraction: with pressure control 
  4. Use filter grind with lower pressure. 
  5. Stainless steel mushroom - will last longer than chrome-covered brass and has no mineral buildup
Kit includes:
  1. Stainless steel flow Control with a brass screw to prevent corrosion
  2. Coffee sensor 6mm black PVC tap x 1 and a choice of 2 handle heights
    1. Non-flip
    2. 180-degree flip handle- Suits models with a low group head.
  3. Coffee sensor pressure gauge 6mm with black face  0-16 bar (The gauge has a direct M6 thread on the back, so the installation is pretty simple and straightforward.)
  4. Teflon gasket for mushroom washer. 
  5. Teflon tape and a small hex wrench are needed for gauge installation;
  6. The bottom group spring is for cancelling the pre-infusion.
  7. Spare set of gaskets: 1 x mushroom gasket +  2 x  o rings for the stainless steel needle valve.
  8. Full-length installation guide and servicing manual
 

Frequently Asked Questions :

  • Q. Is my pump affected by the Coffee Sensor FCD? A. No Pressure reaches the standard 9-10 bar and is adjusted only if FCD is used.  
  • Q. Is the heat-up time affected?  A No, When FCD is at the closed position, it is just above the area where the water circulates slowly inside the GH, with the help of IN and OUT pipes.
  • Q Will my pump be affected in the long term?  A No - The pump will handle the FCD for a long time. The low pressure given by the FCD usage lasts for seconds.  
  • Q Which flow control handle should I use? A. Some coffee machines have a lower-positioned group head, so the standard handle could hit the body of the machine. In that case, it's best to use our flip handle, to avoid the chrome plate from behind the group head.
  • Q What are the spare gaskets for? A.  Spare gaskets are for E 61 mushroom and stainless steel needle valve.
  • Q Do all machines have the same water output? No - Each machine is different, rotary pumps work differently to vibration pumps and manufacturers have different E 61 groups.

Unplug the machine from the electrical socket and let it cool down completely. 

Set the pump pressure somewhere between 9-10 bars.- if not already.
To determine the OEM flow rate of your machine BEFORE installing the flow device, run the water for 10-20 seconds and measure how many millilitres or grams of water come out per second.


Installing the pressure gauge.

  1. Without touching the face/glass, wrap the white Teflon tape (included with the kit ) on the threads of the manometer to ensure a proper seal. 
  2. Rotating clockwise, and without touching the face/glass, finger-tighten (using tools could cause irreparable damage) the manometer onto the grouphead. Tighten until you feel resistance, and make sure the front of the gauge is facing correctly. You don't have to screw the manometer all the way to the end of the thread.  
  3. Use a blind basket to test for any air/water leaks. Don't stand close to the machine when testing. If leaks are present, tighten either the FCD or the manometer.  

1. After installing the flow device, you can determine various flow rates at different angles/points. Completely open or close either handle at the 12, 9, 6, or 3 o'clock position. In these instructions, we will be turning counterclockwise.

2. At the 12 o'clock position there will be no water flow. 9 o clock = 2-3 mL/sec. 6 o'clock = 4-6 mL/sec. 3 o'clock = 7 mL/sec, and so on.
The FCD is directly connected to the group head and will therefore become extremely hot, so when turning the FCD handles, be careful so as not to burn yourself. The handles themselves are made of special heat-resistant plastic.
4. Now you can decide whether you want to create a pressure-only profile (manometer only) or whether you want to introduce flow rate into the mix. We recommend experimenting with a variety of different settings to find your perfect espresso.
.Make sure you don't have worn-out gaskets, springs, scale build-up in your group head, etc. Taking proper care of your machine will guarantee that the FCD functions properly and efficiently.

Over its lifetime, the FCD will not work at its optimum as gaskets and springs can wear, and a build-up of scale can obstruct the needle. 

Tools:

  1. Teflon tape - Included
  2. Electrical tape - to protect the chrome nut
  3. 5mm Allen key for gauge installation.
  4. 12” x 1.5''  adjustable wrench - to remove chrome nut

Coffee Sensor FCD is the best on the market. In contrast to the market competitors the groove at the mushroom is well dimensioned (smaller) , the o-ring fits perfect and is from the right material. It seals properly. No bypass water at pressure.
The gearscrew works incredible precise and repeatable over whole 405 degrees. In knowledge of the physics of pukresistance and extraction the usefull range is from 1/8 to 5/8 out of 8/8 (360 degrees). The change to the harder spring is a must for best results of extraction. Service at the new V2 is very easy.

Coffee Sensor E61 Flow Control

Will it fix a Lelit Mara X?
James from Iceland
Hi James, We don't have any feedback on this fitting Lelit Mara, so cannot say. My best guess is no, probably won't fit. Lelit has its own flow control kit.
Blue Star Coffee Team
Looking at the flow control device, in the installation guide you mention that an 12"x 1.5" adjustable wrench is needed to do the installation. Is this different than classic 12" wrenches? Can you also please mention how wide the wrench exactly needs to go to do the installation in milimeter measures?
Berke from Turkey
Hi Berke, the Chrome nut is 36mm (1.4" inches) most wrenches will fit. A 12" wrench has length to make removal easy.
Blue Star Coffee Team
Hello, I want to ask if this will work for me 100% on the ECM Classica PID? well thank you
Vladimir Fedor from Slovak Republic
Hi Vladimir, Yes - It fits ECM Classika PID.
Blue Star Coffee Team
I have a Rocket Giotto (E61 brew head) and would like to know if: 1) This will fit? 2) Will I need to use the supplied "bottom group spring"? Cheers, Greg
Gregory from Canada
Hi Gregory, Yes it fits Giotto and yes you will need the bottom spring - it cancels the preinfusion.
Blue Star Coffee Team
I have a Profitec 400 pro, I can turn off my pre infusion, so doI still need to fit the bottom spring
STAN from United Kingdom
Hi Stan, The spring is to cancel preinfusion, it's optional so you may not need to use it.
Blue Star Coffee Team
Would it fits Bellezza Valentina?
Adi Zvi from Israel
Hi Adi, We have no data on Bellezza, so cannot say, if it would fit or not.
Blue Star Coffee Team
Does it it a Sanremo Treviso?
Lauro from Mexico
Hi Lauro, I cannot be certain - but it probably does fit Sanremo Treviso, as the mushroom size for Sanremo MILANO LX, TORINO, VERONA.
Blue Star Coffee Team
Hi, is this the 2022 version?
PETROS from Greece
Hi Petros, This was made in September 2023 - so is up to date.
Blue Star Coffee Team
I want the white scale version. Also I am worried that the adjustment is not smooth. Can you please comment on this?
Leonid from United States
Hi Lenoid, This comes with the coffee sensor black gauge as standard. The adjustment should be smooth as the inside the FC, is a pin that is moved by turning the lever - see customer reviews for more info.
Blue Star Coffee Team
Hello, I see that your kit is compatible for the Lelit Mara X (according to your list) but you answer to James from Iceland is that it will probably not fit ?? So, is it ok with Lelit Mara X ?
Michele from Switzerland
Hi Michele, It should fit - we had no feedback at the time, but I understand that it does fit the Mara X.
