Personal Water Meter by Adam Kereliuk

With the growing cost and often shortage of water these days, it comes down to an individual effort to use less. With personal water meter(PWM), people would be able to track their usage on high traffic fixtures in the home such as showers and sinks.

The PWM tracks water usage per day/week/month all in real-time, so you can see exactly what you’re using, when you’re using it. The counter starts and stops when water flow does, so when flow begins, the “single” option will appear on the screen and count from 0 liters to however many you finish with. This amount will then be added into the total liters per day/week/month. Each time frame will reset accordingly.

As water flows through the PWM it spins a propeller. Much like a car will gauge RPM’s, a small sensor will count the revolutions of the propeller, and send the information to the CPU. The speed of the propeller can then be converted into a formula that can determine the volume of water that has passed.
