Automatic dispenser works as follows.

The filling of the supply tank 1 with liquid occurs with the inclusion of the mechanism 51 of the fluid supply by a signal from the remote control 20. In this case, the liquid level rises from the bottom 3 of the supply tank 1 to the level 19 of the nominal capacity, the magnetically controlled contact 16 is electrically disconnected. Through the pipe 24, the excess liquid and part of the gas will be diverted to the underground tank 21. When the magnetically controlled contact 15 interacts with the magnet 29, an electrical signal is sent to the control panel 20 to stop the flow of liquid into the flow tank 1. At the signal from the control panel 20, the liquid flows: electromagnetic the valve is electrically turned on, with the flow mechanism 52 turned on, the supply tank 1 is emptied, liters are counted during the interaction of the magnets 28 with the magnetically controlled contact 16, and the liquid level decreases. After issuing the set dose of liquid at the signal from the control panel 20, the drain solenoid valve 7 is turned on to reduce the pressure of the jet in the dispensing valve 56, the liquid flow is stopped by a signal from the control panel 20 at the pulse meter 17, with the display of the flow rate of the mark 37 and milliliters the mark 38 on extension scale 36.

The claimed invention improves the accuracy of dispensing liquids.
