The measuring complex works as follows:

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

In this case, the filling resolution is ensured both by the operator’s action and from the local control station (Fig. 4 pos. 12), by a set of locks at the loading post (Fig. 4 pos. 10). Including: the grounding device of the tanks (Fig.2 pos.5). The start-up of the complex is carried out from the local loading control post (Figure 4, item 12). When this is turned on, the electric pump unit (Fig. 2 pos. 1) and a valve with electromagnetic control and hydraulic lock (Fig. 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.11) and through the divider (Fig.2 pos.15) wets the walls of the tank.

The display and control unit (Fig. 2 pos. 18) using a measuring chamber of a liquid meter and a pulse sensor (Fig. 2 pos. 3) measures the amount of product entering the tank, displays data on its display, and also provides information to the remote control (Fig.4 pos.7), (computer Fig.4 pos.6). At the same time, in the process of filling / draining, the relative error of the complex is electronically adjusted by the indication and control unit (Fig. 2, pos. 18) based on data on the density of the released oil from the densitometer (Fig. 2, pos. 9), the temperature value from the densitometer (Fig. .2 pos. 9) and (or) a temperature sensor (Fig. 2 pos. 19), the value of the volume from the measuring chamber of the liquid meter through a pulse sensor (Fig. 2, pos. 3).

When you leave 5% of the dose of oil from the remote control (Figure 4 pos.7) or (computer Figure 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 the release of oil continues at maximum flow rate.

5% before the end of the dose of the petroleum product, the valve with electromagnetic control and hydraulic lock (Fig. 2 pos. 4), by command from the remote control (Fig. 4 pos. 7) or (computer Fig. 4 pos. 6), switches to a low flow rate, as a result, there is a reduction in consumption 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 (Figure 2, item 5), when the shut-off valve (Figure 2, item 12) is manually turned off on the filling console (Figure 2, item 11), when capacitive overflow sensors are activated (Figure 2) pos. 14), in the absence of oil at the inlet of the electric pump unit (Fig. 2, pos. 1), when the STOP lever is pressed at the local control station (Fig. 2, pos. 7) and when the power supply is cut off.
