A dosing and weighing device (1) comprising a housing (2) having an inlet opening (3) and an outlet opening (4), and a weighing surface (5), which is operatively connected to at least one weight sensor (7), a mechanism (9) for detecting a pressure difference between a pressure in the housing upstream and a pressure in the housing downstream of the weighing surface (5). Via a control unit (8), the detected pressure difference is used to correct the weight detected by the weight sensor (7).

A weighing system for weighing particulate material such as powders, granules and the like, and particularly particulate foodstuffs. The system includes: a weighing device (9); a vibrator unit (11); a transfer receptacle (7) having an opening; a robotic arm (5) arranged to move the transfer receptacle (7); and a control system (13) arranged to control the robotic arm (5) and the vibrator unit (11); wherein the transfer receptacle (7) is arranged to receive a quantity of the particulate material through the opening; the control system (13) is arranged to actuate the robotic arm (5) to move the transfer receptacle adjacent the weighing device (9), and to actuate the vibrator unit (11) to vibrate the transfer receptacle (7) thereby causing particulate material located in the transfer receptacle (7) to dispense from the transfer receptacle onto the weighing device (9).
