OG exemplary drawing
 
1. An application device for application of an application agent, said application device comprising:
a) a nozzle for dispensing the application agent through the nozzle and
b) a first pressure sensor for measuring a first pressure reading of the application agent upstream of the nozzle,
c) further comprising a second pressure sensor for measuring a second pressure reading of the application agent downstream of the first pressure sensor,
d) at least one first metering device for conveying the application agent with an adjustable first delivery flow rate to the nozzle, and
e) a control unit, wherein the control unit is connected on an input side to the two pressure sensors and receives the first pressure reading and the second pressure reading, while the control unit is connected on an output side to the at least one first metering device and wherein the control unit is adapted to set the delivery flow rate of the at least one first metering device as a function of the first pressure reading and the second pressure reading.
