Liquid flow sensors 8 are factory-calibrated per medium, so the selected medium has 9 to match the fluid actually flowing through the sensor for the 10 reported flow rate to be correct. 11 12 Reading returns the currently active medium; writing one of the 13 strings listed in in_volumeflow_medium_available selects it. 14 15What: /sys/bus/iio/devices/iio:deviceX/in_volumeflow_medium_available 16What: /sys/bus/iio/devices/iio:deviceX/in_volumeflowY_medium_available 17KernelVersion: 7.3 18Contact: linux-iio@vger.kernel.org 19Description: 20 Space separated list of the calibration media supported by the 21 device, e.g. "water ipa". 22
