A clever device for filling auto batteries used a sealed container holding the supply water,a spout with two holes. One hole delivered the water, the other hole delivered air to the sealed container of supply water. When water level rose up to the air hole, flow stopped. As the fill device was removed from the battery, a spring valve shut off the supply water. Very simple, no electronics to fail at all.

"...any other methods...". If this is a production line, you could also fill by weight.

"... filling of 20 liters of water to small tanks by automatic..."

This sounds like a large toilet bowl filler.

Unless, of course, there is a need to make it complicated and wonderful.

Exactly! Now because a simple float operating a valve (toilet bowl filler) is not sufficient then there are unstated concerns here. Are these tanks(?) to be filled, capped and then transported to another location? Is this potable water? Is the water source under pressure and can readily flow into a vessel? Is there some biology or chemistry that must be undisturbed in the water?

Then we enter the questions I love to ask that never get answered. What is the acceptable tolerance in your measurement? 20 liters ± what? STP is a common assumption but is it true here? How fast must these tanks be filled?

It is so difficult trying to help somebody solve what looks like a simple problem. One of two scenarios probably exist. The problem is actually more complicated than stated but the one with the problem cannot or will not explain why it is complicated. The one with the problem is not capable of solving a simple problem.

Hire a kid with a hose.

Make the tanks exactly 20 litres in volume, and pass the delivery hose slowly and automatically over each one at a rate that will fill each of them.

Why don't you use a simple float valve?

thank u all..!giving ur replys..!

Don't know if applicable but the tank could be filled by weight. With temperature variance

Also could use a metering pump. A positive displacement pump like gear pump.

I gave you a GA because I think that is a better and simpler way of doing it.

Hi V S,

Check out the ifm magmeters. Price to performance ratio is great.
