icons for gas, power and water

[Kroonen]

Hi,

I was wondering if there are people well in making nice icons for domotica stuff. I want to make a touch panel, but there are no nice icons for meters of water, gas and power.

If found these on the web, but I can't download it as icons only pictuer as shown, I also think the icons must be transparent
Are there people who know als such nice icons or design them? (or knows to find these as icons)
