I want an alarm if I have a water leak. I have seen water flow meters but they are expensive. There seems to be two types, ultrasonic and direct flow (connect in series). Does anyone know of a DIY project for this or a cheaper device?
 

You can think of resistive mentod too where water need to be conductive....and you insert a rod or wire ....need to do the couple of experiments and you get the emperical relation where you insert another wire with floating ball kind of application on to water surface and give the voltage to end the start of wire/rod that you r inserted in the water.....

Good Luck
 


If you attach a microphone to the pipe just downstream of a discontinuity (such as an open stop-****) then the water will be turbulent when it flows, so you should be able to "listen" to it. Of course you will be deafened by the sound when water is run of for a proper purpose.
Proper flow meters use a little turbine that spins or use the doppler effect on ultrasonic waves to detect if the water is moving.

How small a "leak" do you want to detect? A dripping faucet?...a cracked pipe?...a broken washing machine hose?..????

Hello, guys! per the water leak I creat a float switch with openpicus flyport which sends me an email and it's okay, i have no problem with it.
 

Must be ultrasonic its only long life solution, all other what have contact with water need some maintance or have shorter life.
