Abstract: The present disclosure relates to a method for the detection, characterization and assessment of the quality of a spray which is produced by atomizing liquids with nozzles of different designs and constructional forms. The spray may have an application-specific droplet size distribution ranging from fine to very coarse droplets which move at different speeds. A radar signal is directed into and reflected by the spray. The reflected radar signal is subject to a Doppler shift caused by the movement of the droplets in the spray. The transmitted and received radar signals are mixed to create a low-frequency Doppler oscillation signal which is sampled at a predetermined rate with an analog-digital converter, the output of which is stored in a data array and transformed from the time domain into the frequency domain for further processing.

Abstract: A forage harvester gathers crop by a crop receiving assembly and delivers the crop via infeed units to aggregates for comminuting and conveyance. The crop is then conveyed to a transport vehicle via a discharge chute provided on a discharge tower. A device for adjusting the tilt angle of the discharge chute is provided for guiding the crop mass flow onto the transport vehicle. A method for measuring a crop mass flow on the forage harvester is based on sensing a force proportional to the crop mass flow, which acts upon the device for adjusting the tilt angle of the discharge chute, and calculating the crop mass flow in a computing unit based on the sensed force.

Abstract: The invention relates to a method for measuring the crop mass flow (5) on a forage harvester (1), wherein the crop is gathered by means of a crop receiving assembly and is delivered via infeed units to aggregates for comminuting and conveyance. The crop is conveyed to a transport vehicle via a discharge chute (8) provided on a discharge tower (4). A device (7) for adjusting the tilt angle of the discharge chute (8) is provided for guiding the crop mass flow (5) onto the transport vehicle. The method according to the invention is characterized by detecting the force proportional to the mass of the crop mass flow (5), which acts upon the device (7) for adjusting the tilt angle of the discharge chute (8).

Abstract: The invention relates to a method for measuring a material flow by means of microwaves, a sensor arrangement for measuring a material flow by means of microwaves and a device having a sensor arrangement, and to the use of a monostatic continuous wave radar for measuring a moving material flow consisting of particles or fluid. This has the advantage that the material flow consisting of particles or fluid can be quantitatively detected and/or the particles can be counted.
