In fact it is more complex since AC current must flow through the liquid and not DC which leads in electrolysis and oxidation of the wires.It works only for testing some moments but not for a permanent use.
Things to know: This will only work with conductive fluids, like non-distilled water. For non-conductive fluids, you need a float of some kind. Also, since this requires current to flow, the wires will prematurely corrode due to electrolysis.

Great invention but the wires to the water tank is expensive nowadays for long buildings . What is the elctronic component to use in order to minimize wiring like to use 2 wires only to connect the tank with the internal unit . Thank you.
What about length constraints? I mean if the water tank is around 4-5 meters from the IC, will it work? Also in long term, there could be chance of oxidation.. isn't it?
It works for half an hour only, after that all led s goes off. If I switch off and again on the circuit, leds giving just small blink and then turning off. Pls give a solution 
I made a similar one back in 1977 for my Kavan model Jet Ranger helicopter to make sure fuel will not run low. Thats a long time ago. Now, it's 2020 and I see this.
If used in the home tank then battery is not proper option for it if we used 12v adaptor by dc current... Please tell that way too how we can use dc current by used adaptor
I have a 3000 Imp Gal rainwater tank. will this work with a large tank. I tried the transistor system without resistors. It works in a glass of water but not in the tank? Would the IC 2003 work better?
@@yaqoobgillani5812 cant see how it can work with oil....oil is non conductive so as the level alters each wire on the ribbon cable will register no resistance change.
Instead of battery for power supply i want to connect it to my home power supply, how do i do that. I want to make it for my home water tank which is on 3 floor
And I thought breadboards were crude. 😂 Keep up the good work, I might just as well do this for my water tank in the caravan. This is a perfect example of K.I.S.S

@@gillanidata Hi Great video. Exactly what I've been looking for, for my rainwater harvesting system. May I suggest that you check out some of your replies regarding its suitability for fuel and oil tanks. Some places you say it's OK, others say NOT OK, much I think stemming from the various names for petrol.

You're smart there. Does stainless steel used as probes also corrode? Tell me.
instead of constant current flow you can impulse some current to make the measurement each X minutes (hours etc)
@@mickcarson8504 Yes. Use titanium/platinum/graphite for minimal corrosion.
@@andreylitvinenko783 That would reduce corrosion, but you would need to make your own program for that.
