Beschreibung
Zusammenfassung:	The invention relates to a portable spray device (1) for ejecting a fluid, in particular an agricultural formulation, comprising a container (2) for receiving the fluid, a pump (15) which is fluidically connected to the container (2) in order to discharge the fluid out of the container (2), a spray pistol (21) which comprises a spray opening (27) and an electrically actuatable application valve (20) for opening and closing a passage to the spray opening (27), and an application line (17) which establishes a fluid connection between the pump (15) and the spray pistol (21). The spray device (1) according to the invention is characterized by a pressure sensor (19) which is arranged in the application line (17) for detecting the fluid pressure in the application line (17) and an electric controller (28) which is coupled to the application valve (20) and the pressure sensor (19) so as to transmit data and by means of which an electric control signal for opening the application valve (20) for a specific time interval specified ahead of time and for closing the application valve (20) after the time interval has expired can be generated on the basis of the fluid pressure detected by means of the pressure sensor (19) such that a defined volume of the fluid is ejected via the spray opening (27).
