Abstract
The present invention relates to a device in a filling machine, said filling machine comprising a filling pipe for supplying liquid food to the tube of packaging material, a pipe for supplying pressurized sterile air to the tube of packaging material, and a gasket for sealing against the tube of packaging material and any pipes inside the tube, for creating an overpressure in the tube. The device further comprises a first pressure gauge for measuring a first pressure inside the pipe at a location upstream from the tube, a device for determining an air mass flow in the pipe, and a control unit for receiving the measured parameters, where the control unit is adapted to calculate the pressure in the tube based on the air mass flow and the first pressure, according to a first pre-established relationship. The invention also relates to a method being implemented by the device.
