Desiring to make a high-quality product that works best for the customer, we teamed up some of our partners and clients to design the e61 Flow control Device. We have them manufactured in a trusted facility that adheres to our strict standards.
Our new 2022 model version comes with few pluses, like:
Available custom wood handles are (purchased separately, since we offer one plastic handle standard for each FCD kit):
e61 Flow control Device offers:
• Simple, straightforward installation
• Compatible with virtually all Profitec, ECM, Rocket (incl. R58), Lelit Mara/Mara X, and other well-known brands/models (Please note that although the Coffee Sensor FCD may work for other machines not listed, we cannot guaranteed it will be compatible with those machines).
• Uses a special needle valve that allows the user to adjust water flow rate into the grouphead to manually profile espresso (e.g. long pre-infusions for higher extraction/saturation)
• Bottom group spring for canceling the pre-infusion.
Coffee Sensor Flow Control Device kit includes:
• Stainless steel flow device constructed with a brass screw to prevent corrosion
• Two unique handles, both 100% compatible with all E61 machines
• Grouphead pressure gauge (0-16 bars)
• Full-length installation guide and servicing manual
What does the e61 Flow control Device offer me?
• Long pre-infusion—as long as you want!
• Control your flow rate—full power for darker roasts or gentle pre-infusion for lighter roasts
• Extract like a lever-machine—you control how many bars you want
• Experiment with coarser grinds using immersion techniques
Proper/Safe Use (Please read carefully)
1. NEVER install or uninstall while the machine is warm. Let it cool down 100%. And always unplug the electric socket.
2. Set the pump pressure somewhere between 9-10 bars. If it’s already set to that amount, you’re good to go.
3. Determine the OEM flow rate of your machine BEFORE installing the flow device. How? Before installation, run the water for 10-20 seconds and measure how many milliliters or grams of water come out per second.
4. Installing the manometer. It is very important that you do not touch the face/glass section of the manometer; doing so could cause issues. Without touching the face/glass, wrap the white Teflon tape (included with purchase) on the threads of the manometer to ensure a proper seal. No other sealant is necessary during this step. 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 manometer is facing horizontal. You don’t have to screw the manometer all the way to the end of the thread. Even if there will be still possible to screw this inside, the Teflon tape will ensure that the connection stays seal even if you did not go all the way though. Use a blind basket to test for any air/water leaks. DO NOT stand close to/in front of the machine when testing. If leaks are present, further tighten either the FCD or manometer. If no leaks are present, you’re good to go!
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 counter-clockwise.
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.
3. The FCD is directly connected to the grouphead 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 a 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.
5. Although bringing the FCD into your workflow can introduce new excitement, and can also introduce new problems. Make sure you don’t have worn-out gaskets, springs, scale build-up in your grouphead, etc. Taking proper care of your machine will guarantee the FCD functions properly and efficiently.
Is the FCD going to affect the pump?
No. Everything inside will still work the same. The FCD only controls the amount of pressure that will build up in your group head (9-10 bars). Pressure will increase or decrease after reaching the FCD working point.
Will having the FCD in the closed position affect how fast the grouphead will heat up?
No. Even if the FCD is in the closed position, it is located directly above where the water circulates and will slowly come into the grouphead.
Will the FCD have a long-term effect on the pump?
No. A standard-issue pump will last a long time in tandem with our FCD.
Which handle is better to use?
They’re both equally good. Depending on the machine, groupheads can be located in a low or high area. If the grouphead gets in the way of the turning the handle, trying using the flip handle instead to avoid damaging the chrome plating.
Why did it come with spare gaskets and food-safe lubricant already applied on the needle valve?
We included these as a bonus for you. It’s important to lubricate the FCD from time to time, and the gaskets are there for servicing purposes.
Does it come with a warranty?
Yes. All metal parts come with our Coffee Sensor lifetime warranty.
Will the water flow rate be the same on every machine?
Not necessarily. Some machines use a rotary pump, some use vibe pumps. The FCD simply gives you the ability to control the standard flow rates.
