The present invention relates to a portable spraying device () for discharging a fluid, in particular an agricultural formulation, having a container () for holding the fluid, a pump (), which is in fluid connection with the container (), for pumping the fluid out of the container (), a spray gun (), which comprises a spray opening () and an electrically controllable application valve () for opening and closing a passage to the spray opening (), an application line (), which establishes a fluid connection between the pump () and the spray gun (). The spraying device () according to the invention is distinguished by a pressure sensor (), which is arranged in the application line (), for detecting the fluid pressure in the application line (), and an electric control device (), which is coupled to the application valve () and the pressure sensor () in terms of data transmission, by means of which device an electric control signal for opening the application valve () for a certain predetermined time interval and for closing the application valve () on expiry of the time interval can be produced in accordance with the fluid pressure detected by means of the pressure sensor (), with the result that a defined volume of the fluid is discharged via the spray opening ().
