The Nanotube is a ball flowmeter for delivering oxygen or medical air to patients with respiratory insufficiency. It utilizes the results from the company’s research and development program. It connects to wall gas outlets directly or indirectly with a hook and rail mounting.

The pressure-compensated flowmeter (scale measures at the inlet pressure, insensitive to pressure variations) is available in flow rates of 0-1 L/min, 0-7 L/min, 0-15 L/min, and 0-30 L/min for oxygen and air.
