65 is the platform.

The liquid dispenser operates as follows.

During installation, the supply tank 1 is installed on the platform 65 at level 25, by means of racks 59, 60, 61 with jacks 62, 63, 64. To fill the supply tank 1, the operator opens the taps 49 and 50 and from the portable control panel 34 of the operator sends an electrical signal to the inclusion of the fluid supply mechanism 36 through the pipe 38 through the filter 37, the jet expander 39, the wave damper 26 with holes 27. The liquid 52 rises up the supply tank 1 at the same time through the pipe 7 and 8, the extension scale 5 is filled, on which a replaceable metal strip 9 s is installed reference marks of liters 10, with a movable indicator fixed on it 11. The marking of the reference of liters is reduced to the average seasonal air temperature according to the regulatory document of Gosstandart of the Russian Federation MI 2395-2004.

The faucet 15 is opened, filling the capacity of the additional tank to the mark 18, then the faucet 15 is closed through the pipe 4, the gas passes to the tank 48. Having reached the set level of the supply tank 1, the level sensor 55 is activated, an electrical signal is sent to turn off the fluid supply mechanism 36, excessive the liquid 52 is discharged into an additional tank 6 with a metal strap 12 installed with millimetric reference marks 13, and a movable indicator 14 fixed to it.

The movable indicator 14 is moved along the bar of the additional tank and set to the level of its filling. The mobile indicator 11 is moved to the label of a specific dose of liquid.

From the control panel 34, it gives an electrical signal to turn on the fluid flow mechanism 40 through the non-return valve 41, pipe 58, filter 43, hose 44, and dispensing valve 45. The filling station operator dispenses fuel on the remote scale 5. The liquid 52 drops down. Having reached the mark of a certain dispensed dose, the operator sends an electrical signal from the control panel 34 to turn off the fluid flow mechanism 40. If the fluid level does not coincide with the mark 10 by an indefinite volume, the operator opens the valve 15 from the additional tank 6 with marks 13 of the milliliter reading through the nozzles 16 and 17, top up the liquid to a match above the standing mark on the extension scale 5 with marks 10 and the amount of liquid volume topped up from the additional reservoir 6 with marks 13 counting in milliliters. The operator determines the actually dispensed volume of fuel, then opens the valve 15, the liquid is drained into the supply tank 1. After the liquid is drained, the valve 15 is closed. In the future, the liquid dispenser operation process is repeated. The amount of dispensed liters is recorded in the journal with the signature of the consumer. The total metering of fluid flow per shift of a filling station operator is made by the tank using calibration tables approved accordingly. With the closure of the filling station, the taps 49 and 50 are closed, the voltage is removed from the liquid dispenser.

The claimed invention improves the accuracy of dispensing liquids.
