Superior Flow
With most touchless faucets, water flows for a fixed period, or as long as your hands are moving in front of the sensor.
The Flow by Bemis Grove Bathroom Faucet displays the water temperature on an LCD screen beneath the touch- or motion-activated, frosted-glass-topped tap. The design, which will start at about $199 and is targeted for a June release, also times the water flow to encourage proper hand washing.
