+ * Sensor96                        - Show current settings
+ * Sensor96 1 <correction-factor>  - Set sensor 1 factor (x 1000) - to set to 0.2 enter 'Sensor96 1 200'
+ * Sensor96 2 <correction-factor>  - Set sensor 2 factor (x 1000)
+ * Sensor96 9 0|1                  - Show flow value in l/min (0) or m³/h (1)
+ *
+ * Flowmeter calibration:
+ * - get the current displayed flow rate (D)
+ * - get the current <correction-factor> (c)
+ * - measure the real flow rate          (M)
+ * - new <correction-factor> = M / (c * D)
+ *
+ * Example:
+ * - displayed flow rate = 254.39 l/min (D)
+ * - current <correction-factor> = 1.0  (c)
+ * - real flow rate      =  83.42 l/min (M)
+ *
+ * new <correction-factor> = M / (c * D) = 83.42 / (1 * 254.39) = 0.328
+ * Cmd: Sensor96 x 328
