ABOUT)

The invention relates to a measurement technique and can be used for dispensing a given mass of bone in various sectors of the industry. A device for measuring the discharged mass of a liquid, containing a reservoir of liquid, is known, often with a force sensor mounted on the reservoir, a submersible element / connected to the sensor, and a zero mass recognition unit. The disadvantage of this device is low accuracy and speed when tempering is fixed, i.e. predetermined dose, which is explained by the inertia of the liquid flow cutoff device. The closest in technical essence to the present invention is a device comprising a reservoir with a liquid, a pontoon floating on the surface. Liquids, and a mechanism for grenergling on the pontoon C2. A disadvantage of the known device is the low speed and low accuracy due to the influence of the environment. The purpose of the invention is to improve accuracy by reducing the influence of the environment, as well as increasing reliability while maintaining accuracy. The goal is achieved by the fact that a device for dispensing a given mass of fluid, containing a fluid reservoir, a pontoon floating on the surface of the fluid, and a mechanism for girding on the pontoon is equipped with a two-valve manifold in the lower part of its cavity with pipes to supply fluid to the reservoir and dispensing it into a container, the tank being made airtight with a water inlet in the middle part connected to the collector, a source of compressed gas is connected to the top part of the tank through a pressure regulator and a valve, and enalozheni multiposition formed. In addition, the mechanism of the fire overlap is made in the form of electromagnets connected by poles with permanent magnets and placed on the lid of the reservoir. The drawing shows a device for dispensing a given mass. The device contains a reservoir 1 with a liquid, a pontoon 2, floating on the surface of a liquid, a weight 3 of a given mass, a mechanism 4 of hydroplane, a collector 5 with two valves 6 and 7, in the lower part of the cavity of the collector 5 connected by pipelines 8 and 9 with a reservoir 10 for the main storage of products and containers filled 11, with the tank 1 being provided with an orifice 12 in the middle part. In addition, the device contains additional weights 13, a source of compressed gas with a gearbox 14 and a valve 15 connected to the upper part of the reservoir 1, which is made airtight, and the mechanism of the hyperelance is multi-positioned in the form of electromagnets 16 and permanent magnets 17 connected to each other poles and located on the lid of the tank 1. In addition, the device contains a flexible pit-hose hose and undercarriage J (not shown) to move around the site, of which the empty container is located. The device works as follows. In the initial state (after installation), the tank 1 .. is empty, the pontoon 2 with the weight 3 of a given weight is at the bottom of the tank 1, the valves b and 7 are closed, the mechanism 4 is overlaid. Upon receipt of the application for leave, the valve b opens, the mechanism 4. The heating overlay is prepared for operation, and then the centrifugal pump is turned on, the reservoir 1 is filled in through the pipeline 8 from the primary storage tank of the petroleum product, and the valve 7 is closed. After fixing the weight 3 of a predetermined mass by the mechanism 4 of the hyperelance, i.e. after attachment of the weight .4 to the magnet, the centrifugal pump and the oil product, which creates the pushing force, which, in turn, provides movement of the pontoon 2 before the weight 3 is fixed by the mechanism of the hygroalignment, is discharged through the open valve 6 to the main storage tank of the oil product to the level of the hole and 12 in the collector 15. The pontoon floats in the tank 1 without the weight 3. After closing the valve b and opening the valve 7, the mechanism of the hyperelance works and the fluid displaced by the pontoon 2 with the weight 3 (equal in mass to the weight through the valve 7 through the pipes The cable 9) is poured into the filled container 11. To increase the speed, it is possible to switch on, at the same time, the mechanism of the hyrenalignment, the valve 15, which fills the reservoir 1, sealed to the source of compressed gas with the gearbox 14. After filling the container 11, the valve 15 is closed . The increase in accuracy (at least by 0.4%) and reliability of the device is due to the absence of moving parts, constant mass of the weight and its independence from environmental parameters (temperature, humidity, pressure).
