Alphacool 17356 Eisfluegel Flow Indicator Blue 6-11mm - Plexi Water Cooling Controllers

I have a K40 laser and this gives you confidence that the tube is being cooled with a quick glance

Bought this indicator to show whether my seal pump was working on my boat, worked a treat!

I wanted a visual indicator that water was constantly flowing for the water pump n my laser cutter as you can cause a failure in the laser tube with overheating if the water pump fails or tubes get blocked. I had a good look round at what was available; I could have got one designed for PC cooling which I am sure would have been fine but I would have then had to purchase additional fittings, I do find for such a simple basic item these are expensive for what they are but that’s not a dig at this product they are all around the same price or you can go for an all singing and dancing one far more expensive. Fitting is really simple just pushing the inlet tube to one end and outlet tube to the other, it works as it should and does the job I want it to do, I do plan to put a little LED behind it to make it more prominent but still ideal as it is. Overall does exactly what I wanted, the finishing is a bit rough and the reason I have given it four stars rather than five.

good product ,exactly what i needed,

description accurate, price reasonable

Besonders praktisch wenn die Pumpe nicht zu hören ist. So sieht man ihre Funktion durch den Durchfluss.

looks great in my loop, I went head and bought one red and one blue for aesthetic purposes, as well as to know that my pump is working. One of the sides of the flow indicator is glued on, I'm hoping that it lasts a long while and doesn't burst open randomly and ruin my computer so I'm not sure really how long they're meant to last

Es muy facil de instalar, me llego muy rapido y no hace nada de ruido, ademas de ser un buen chivato por si la bomba de agua se rompe y no hace el flujo de agua!. y para aquellos que tengan dudas como a mi me paso de como instalar este componente a la refrigeracion liquida es muy sencillo, corte y a presion para el tubo! y no sale ni gota y queda IMPRESIONANTE!

alles ok
