- Pumping station 3,

- Tank Park 4,

- Cabinet control and distribution 5,

- Local control post 12.

The measuring complex works as follows:

The tank is poured at the filling station (Figure 4, item 10) at the dose set by the operator on the remote control (Figure 4, item 7), computer 6 and from the local control station (Figure 4, item 12).

In this case, the filling resolution is ensured both by the action of the operator and the local control station (Fig. 4 pos. 12), a set of locks at the loading post (Fig. 4 pos. 10). Including: grounding the tank (Figure 2, pos. 5), installing a filler pipe in the neck of the tank.

The start-up of the complex is carried out from the local loading control post (Figure 4, item 12). This turns on the electron coaxial unit (Figure 2 pos.1) and a valve with electromagnetic control and hydraulic lock (Figure 2 pos.4) at a low flow rate. The oil product, at the choice of the remote control panel (Fig. 4 pos. 7) or a computer (Fig. 4 pos. 6), is supplied through an electromagnetic valve corresponding to this type of oil product (Fig. 4 pos. 9) to the selected filling console of a sealed top loading (Fig.2 pos.8) and through the divider (Fig.2 pos.15) wets the walls of the tank.

The liquid meter (FIG. 2, pos. 3) measures the amount of product entering the tank and gives out pulses through the pulse meter of the fluid meter (FIG. 2, pos. 3) to the remote control (FIG. 4, pos. 7), (computer .4 pos. 6), where the quantity of the poured product is counted. At the same time, the countdown of the amount of product entering the oil product tank is carried out at the loading post counter (Figure 4, item 10).

When 5% of the dose is dispensed from the remote control (FIG. 4, pos. 7) (computer, FIG. 4, pos. 6), a command is issued to turn on the valve with electromagnetic control and hydraulic lock (FIG. 2, pos. 4) at a high flow rate, and oil product sales continues at maximum flow rate.

5% before the end of the dose, the valve with electromagnetic control and hydraulic lock (Fig. 2 pos. 4), upon command from the remote control (Fig. 4 pos. 7), (computer Fig. 4 pos. 6), switches to a low flow rate, as a result which reduces the flow rate for a more accurate cut-off of the dispensed dose.

At the end of the dispensing, the remote control (Fig. 4 pos. 7), (computer Fig. 4 pos. 6) issues a command to turn off the valve with electromagnetic control and hydraulic lock (Fig. 2 pos. 4), the electromagnetic valve (Fig. 4 pos. 9), as a result of which the valves close and filling stops.

Product loading automatically stops when grounding is violated (Fig. 2, pos. 5), manually shut off the shut-off valve (Fig. 2, pos. 12) on the fueling console (Fig. 2, pos. 11), when capacitive overflow sensors are activated (Fig. .14), the absence of oil at the inlet of the electric pump unit (Figure 2, pos. 1), when the STOP lever is pressed at the local control station (Figure 2, pos. 7) and the power supply is cut off.
