Need electronic water level indicator !!

I need a water level indicator..
Maybe a LED kit that show how much water there is in my water tanks !

I think what I need is 3-4 LED , Low, Middle, High, and a second TO MUCH ! haha


I have seen a KIT how to build one, with simple Transistor and a resistance..
But when I try to search for the components to build one, I did not manage to find them.

Hi Filip, you can use this one http://www.elektro-kahlhorn.de/images/product_images/popup_images/reifa-e.jpg its called Schwimmerschalter (swimming switch) in German, this is a simple switch, pond Pumps often use this to controll the water level.

When the water is going down, the switch close the contact or iverse. you just mount the cable on top of your tube, the water and the swich do all the work. Hope you understand what i mean.

There are diferent switches out there, opener, closer and 2 level inicators.

Yes I this I can use

It can shut off my pumps if the water is to low !!

But I still maybe also want to have a LED indicator, so I know how much water there is in my system..
