Kegbot on touch pad cable connections

Just bought the kegbot and hope to run it with my hp touch pad sitting on a touchstone charger. Will this micro usb to female usb be all I need to interface with android? http://www.amazon.com/gp/product/B00KILQLKE/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

Any tips on where to place the flow meter on the beer line or where to run out the cable? I am already running a tower cooler cord and a temp sensor wire for a temp control unit through the co2 hose opening.its very tight. I have no problem running the cable through my tower. How big of a hole will I need to run the cable? Maybe put a nice grommet on it to help seal? thanks in advance. Steve
