Details
The Alphacool Eisfluegel Aurora Flow Indicator "HighFlow" with RPM-Signal is a flow sensor with two G1/4 threads that can display a water flow rate of 70 to 300L/h. It reports the flow as an RPM signal through a 3-pin fan connector and is lit by 8 addressable Digital RGB LEDs. Alphacool points out that it only works from a flow rate of 70L/h.

High Flow Sensor
Alphacool calls the Eisfluegel Aurora the choice for anyone who would like to measure their water flow and values a great look. This one is designed for high flow systems. Connected via the 3-pin header to a fan header on the mainboard, it sends the speed of its impeller, and the flow rate can then be determined from that reading. Because the housing is made of plexiglass, the flow can also be seen visually. Alphacool's manual includes a speed and flow rate test, an overview that shows which speed stands for which flow rate.
Digital RGB LEDs
The sensor has its LEDs around the circumference of the flow meter, where they run around the impeller and form a circle. Since each LED can be controlled individually, all effects that the controller can produce can be created. The connection is made via a 3-Pin JST connector, which makes the sensor compatible with all other Digital RGB products from Alphacool. If, however, you prefer to control the lighting directly via the mainboard, you can use the included 3-Pin 5V adapter. The manual's caution belongs here: make sure the aRGB header supplies no more than 5V, because a higher voltage will destroy the LEDs.
Integration into the loop
Which thread is used as IN or OUT is up to the user, as the sensor will work both ways. The Eisflügel flow sensor, as Alphacool also spells it, is lightweight and can therefore be freely suspended in the system. On the lower side there are two screwing possibilities for the enclosed M3 screws, for when you wish to secure it. This allows the sensor to be placed anywhere in the case. In the scope of supply there is also a small self-adhesive velcro mat, which can be used for the installation as well.
What the loop needs
Two G1/4 threads are used to install it, so it takes two G1/4 fittings. For the readout it needs a free fan header on the mainboard. For the lighting it needs a Digital RGB controller with a 3-Pin JST plug or a 3-Pin 5V header.
