DIY Arduino water meter with iPad display

TEAGUE Give Water from TEAGUE on Vimeo.

It’s another arduino stuff to be working on here. All related references are included:

Some of the folks over at Teague Labs have been noodling around with measuring water consumption. They’ve built a graphing water meter using a YellowJacket Arduino board with built-in WiFi and coolant flow meter from a PC cooling system to see how they used water around the office. Water conservation is major concern in many areas around the world. Tools that allow us to observe and correct our behaviors help us towards a path to sustainability. Schematics and source code are available if you want to try it out for yourself.

What on Earth is NRW?

Saturday, April 26th, 2008

Trust me, I never heard any kind of phrase such of that. NRW is stand for Non-revenue water, generally can be applied in water works industries. I was akin of knowing this when my client is NRW department of A Malaysian company, Syarikat Bekalan Air Selangor Berhad (SYABAS). I was a bit ashamed when I found out that I don’t really know what is NRW means. That means, I don’t know my client. LOL.

Non revenue water (NRW) is water that has been produced and is “lost” before it reaches the customer. Losses can be real losses (through leaks, sometimes also referred to as physical losses) or apparent losses (for example through theft or metering inaccuracies). High levels of NRW are detrimental to the financial viability of water utilities, as well to the quality of water itself. NRW is typically measured as the volume of water “lost” as a share of net water produced. However, it is sometimes also expressed as the volume of water “lost” per km of water distribution network per day.
