FIELD: measurement equipment.SUBSTANCE: invention relates to an assembly for supply of light oil products for filling in systems for selection and commercial metering of shipment of oil products at racks of railway or automobile filling of gallery or clock type. The assembly for selection and metering of shipment of liquid products includes a manifold connected to at least two supply pipelines for supply of at least one product, a shutoff device of pipelines, which provides opening and closing of supply pipelines for supply of at least one product to the manifold; besides, downstream the manifold there located is at least one device for measurement of product flow rate, which can determine product flow rate; with that, the assembly for selection and metering of shipment of liquid products has a possibility of being emptied by gravity through the main filling line located downstream relative to the manifold. Due to location of the measuring device after the manifold, the amount of necessary measuring devices can be reduced at reliable and uninterrupted operation of the assembly, as well as possibility of necessary redundancy. With such layout, one or minimum number of measuring devices can be used for shipment of the whole list of liquid products, namely light oil products.EFFECT: improving reliability of supply of liquid products, possible redundancy of measurement lines for improvement of uninterrupted operation of the assembly as a whole; simpler design; lower costs for construction, procurement of equipment, operation and control of serviceability of equipment at provision of a compact assembly structure.40 cl, 12 dwg |
