HE-VA Flow-Monitor guarantees a competitive and effective control of your pneumatic air seeder, by which you easily and simply avoid unsowed "lines" in the field - without leaving the cabin all the time. In case of a blocking, the display shows exactly the actual seed outlet which is to be serviced, before leaving the cabin. This equipment can control up till 128 seed outlets - corresponding to a 16 m seed drill. The display in the cabin shows 16 rows at a time. The Flow-Monitor measures the number of seeds/grains passing each sensor per second. If the seed rate is falling or hoses are being blocked, an audible alarm will be activated, and the control lamp will indicate which module- and sensor number causing problems. Can be mounted on all types of air seeders with working widths from 3 to 16 m.
