Help me with it, I want solution for automatic under ground water pipes leakage detection

 

You're not giving us much to go on. Why don't you tell us what the solution might look like. Why do you think that nobody makes such a device? You might start by telling us what is in the pipes. Are we talking community water or hazmat refinery?

 

I am talking about the community water pipes, n I there are many solution for that but I want some solution for device which can be locally used so it must be cheaper

 

Unless you can know that there is a period of time when no water is being used, then it is going to be difficult to separate flow caused by real usage from flow caused by leaks.

 

What does "locally used" mean? Where are you?
Cheaper than what? $1.00, or $10.00, or $100.00

I need to design a device that supplies cheap energy. Can you help me?

That questions is just as ridiculous as yours. If you want help, you are going to have to put in a LOT more effort than you have done so far.

 

I'm working on a project that can be use in water pipes, that device emits the laser in all the direction and collect response and by the graphical result i'll collect the result which will show the leakage in outer part of that pipe so is it possible by a laser??

 

This vaguely reminds me of TIR(Total internal reflection),for the "device" to emit laser ,should the device actually be inside the pipe?

AK

 

Yes it should be inside the pipe

 

And this question was posted in "Embedded Systems" because it's going to be "embedded" in the ground...

 

The physics of this proposition escapes me. How is a laser inside a pipe supposed to detect leakage? What happens if the pipe makes a 90° turn?

 

Actually, we r trying to built a device which can flow in water with it's flow and on that device laser will be mounted

 

Like Papabravo, I don't see how this is supposed to work .
How big is this thing relative to the pipe? Won't it block the flow?
How will you get power to it and signals from it?
How will you get it into the pipe and extract it, without losing water?
Is the pipe plastic or metal (metal would block attempted RF communication from outside)?

It's already starting to look far from cheap .

 

Who came up with this idea? Have you seen something remotely like it? I don't see how your idea has any possible practical realization. Never mind being cheap.
