The Coffee Sensor Flow Control Device for E61 groups allows you to adjust the flow of water inside your E61 group head so that you can manually profile your extractions. The main b ody is made from 100% stainless steel (best known and used material since it resists corrosion and is food safe).The kit also contains a small brass screw that’s inside the product and two chromed brass handles. The Coffee Sensor Flow Control Device for E61 allows the user to vary the amount of water flowing through the group head, due to its special needle valve from inside, that goes up or down, during use of our two special handles.Different flow control allows for lengthy pre-infusion for even more saturation and extraction of your espresso drinks.The product is designed to match standard E61 groups.Due to the modification of flow, the result is actually a change in pressure.All changes are directly shown on the included pressure gauge which needs to be attached on the front of the group.The gauge has a direct M6 thread on the back, so the installation is pretty simple and straight forward.
