Connecting a flow sensor directly to BBB

I am trying to connect a flow sensor directly to my BBB revC running Ubuntu trusty. I Have Strangebrew Elsinore up and running with 8 DS18B20 i-wire sensors. I want to utilize a hall sensor based flow sensor without having to get Arduino involved if possible. I am suffering sensory overload with this simple, I hope, task. Any help would be appreciated or even pointing me in the general direction.

Looks like there’s a 1 wire driver that you can use: http://webshed.org/wiki/RaspberryPI_DS1820#Software

Brandon, Thanks for the link, been experiencing google overload but hadn’t seen this site yet.
