Description

The invention relates to devices designed for automated measurement of mass, volume, density parameters, temperature and pressure of oil, petroleum products and other liquids during tempering from tanks to road or rail tanks, upper, lower or combined method, as well as for receiving from road or rail tanks in tanks and transfers between tanks.

The closest to the proposed solution is the measuring complex (Patent No. 2357915, B65G 65/30), which contains a pump with a pipeline installed in series, a filter gas separator, a flow meter, a shut-off valve, a loading riser, a liquid filling tip with a conical sealing lid for the hatch of the tank , pipeline for vapor removal, personal computer, control controller, sensor for monitoring the upper concentration limit, sensor for monitoring the lower concentration limit.

The present invention is to improve the reliability of the system and simplify its design. This is achieved by:

- horizontal arrangement of the filter-gas separator;

- maintenance of the filter-gas separator without spills;

- reducing the service time of the filter gas separator (cleaning and replacement of the filter element) due to the use of the quick-release cover;

- changes in the direction of the scheme of movement of the product - bottom-up, which leads to more accurate accounting;

- the tip of the filling, made in the form of two telescopic tubes interconnected by a winch to lift the telescopic tube, having a convenient handle for manipulating the tip, a cover with clips for fastening to the neck of the tank, providing hermetic filling;

- vapor removal pipe made of metal pipes;

- the location of the electric pump inside the frame ACH;

- combining the sensor monitoring the upper concentration limit and the sensor monitoring the lower concentration limit in one product - the sensor of the maximum concentration of gas.

The proposed measurement system for dispensing product to tankers in the lower and combined method of loading, as well as for dispensing product to rail tank cars. The measuring system is designed for receiving and dispensing product from tank trucks to tanks and tank trucks and for receiving and transferring product from rail tank cars to tanks and between tanks.

FIG. 1 shows the structural hydraulic diagram of the measuring system.

FIG. 2 shows the layout of the measuring system.

The measuring complex consists of pump 1, filter gas separator 2, check valve 3, flow meter 4, shut-off valve 5, bulk riser 6, bulk nozzle 7, gate valve 8, pipeline for vapor removal 9, controller 10, grounding pliers 11, personal computer 12, the air valve 13, the sensor of the maximum concentration of gas 14, the temperature sensor 15, the pressure sensor 16.

The measuring system works as follows.

After the operator has set the required dose and the driver has completed all the preparatory operations, the controller issues a command to turn on the pump and open the valve for low productivity. After the programmed amount of the dispensed product has expired, the controller issues a command to the valve for the nominal capacity, and at the end of the dose for low flow and for closing the valve and turning off the pump.
