What:		/sys/bus/iio/devices/iio:deviceX/in_volumeflow_medium
What:		/sys/bus/iio/devices/iio:deviceX/in_volumeflowY_medium
KernelVersion:	7.3
Contact:	linux-iio@vger.kernel.org
Description:
		The calibration medium the flow sensor uses to convert its
		raw reading into a volumetric flow rate.  Liquid flow sensors
		are factory-calibrated per medium, so the selected medium has
		to match the fluid actually flowing through the sensor for the
		reported flow rate to be correct.

		Reading returns the currently active medium; writing one of the
		strings listed in in_volumeflow_medium_available selects it.
