  • the controlled activation can be used to ensure that the headspace of the container is completely filled with foam and foaming over can be prevented.
  • FIG 8 a third embodiment, not according to the invention, of the method for foaming a filling product in a container is shown schematically.
  • a measuring device 2 is used here, which differs from the figure 6 shown embodiment differs in that the container sensor 22 is arranged after the frothing element 111.
  • figure 9 1 is a flow chart of the method steps of the third embodiment of the method for foaming with the measuring device 2, which is not according to the invention figure 8 shown schematically.
  • the steps S1 to S3 according to the first embodiment relating to figure 5 has been described.
  • a further container sensor (not shown) is provided in front of the foaming element 111 .
  • the control parameters for generating the energy that is necessary for filling the header area can also be used in another way, for example by using values from databases or from preliminary tests.
  • the method begins with step S4. Steps S4 to S6 are as described with reference to FIG figure 5 described, carried out.
  • step 6a the distance from the container mouth x1a is then measured.
  • Step S7 is then carried out, ie the distance from the surface of the foamed filling product is measured.
  • step 8-3 different from step 8-1 of the first embodiment figure 5 and step 8-2 of the second embodiment figure 7 the distance x4 from the surface of the foamed filling product is compared with the distance x1a from the container mouth 40, which was measured after the energy input into the filling product.
  • the control parameters in particular the laser pulse energy, have to be changed. These changed control parameters are then used for the following containers in step S6.
  • the originally determined control parameters for controlling the foaming element are used for the next container 4 .
  • the controlled actuation can be used to ensure that the top space of the container is completely filled and foaming over can be prevented.
  • FIG figure 10 An example of a control loop that can be used with the present invention is in FIG figure 10 shown schematically.
  • a laser controlled by means of a control circuit can be used instead of an HDE for foaming the filling product.
  • the HDE can be replaced by a laser beam source, which sends controllable laser pulses from above through the container mouth onto the filling product and can thus cause foaming.
  • two identical sensors are used to measure the fill level or foam level.
  • a control circuit for controlling the laser pulses can be set up.
  • the first sensor measures, for example, the foam level after the filling product has been completely filled in the container and in front of the laser station.
  • the height difference to be foamed i.e.
  • the distance between the foam level, which can be expressed by the filling height, H F , and the container mouth defines the required pulse energy of the subsequent laser pulse.
  • the second sensor which is positioned between the laser and the capper, measures the result, i.e. the actual status after foaming, and thus detects deviations from the target status.
  • a controller readjusts the pulse energy of the laser beam so that the deviation is eliminated.
