Systems for measuring the quantity and quality indicators of oil SIKN (analogue of KUUN)

Purpose The system for measuring the quantity and quality of oil (SIKN) and the system for measuring the quantity and quality of crude oil (SIKNS) are intended for: measuring the mass (volume) of oil and oil products by the method of direct or indirect dynamic measurements; measuring technological and quality parameters of oil and oil products (density, viscosity , moisture content, pressure, temperature); display (indication), processing and registration of measurement results. Composition of the system for measuring the quantity and quality of oil In the general case, SIKN (SIKNS) consists of a technological part and a system for collecting and processing information. The main composition of the technological part: filter block (BF); block of measuring lines (BIL); block for measuring the quality of oil (BIK); block of a calibration facility (BPU); information processing system (SOI). The technological part may also include: a flow and pressure control unit; a mobile connection unit ; technological and drainage pipelines. Variants of execution of the oil metering system: At the request of the Customer, SIKN can be: open design – the basis is a frame structure for installation in an open area or in a room; closed design – the equipment is placed in a block-box, which has a welded metal frame with thermal insulation. Filter block (BF) serves for cleaning from mechanical impurities and prevent clogging of working units. The unit includes two filters (working and backup) with a quick-detachable cover, inlet and outlet manifolds, shut-off valves, differential pressure sensors and pressure gauges. A block of measuring lines (LIL) is used to measure the flow rate and control oil parameters. The number and diameter of the measuring lines are determined by calculation, depending on the maximum flow rate and the type of flow transducer used. The block of measuring lines includes: measuring lines, mass and volumetric flow transducers, pressure and temperature sensors, flow controllers, a connection unit to a calibration rig, inlet and outlet manifolds, shut-off valves, devices for a leakage control system. serves to control and measure the quality parameters of the pumped oil and oil products. The main equipment of the BIK: circulation pumps (main and standby), fine filters (main and standby), in-line density converters, in-line moisture content converters, in-line viscosity converters, flow transducers, temperature and pressure sensors, manometers and thermometers, automatic samplers, flow controllers oil, flushing systems, shut-off valves; a calibration unit (BPU), the main element of which is a pipe-piston calibration unit (TPU), which is used to monitor metrological characteristics and verify volume and mass measuring instruments at the site of operation. A flow and pressure control unit is being developed and, if necessary, a system for measuring the quantity and quality of oil is designed and installed at the output. The information processing system (IDS) provides automated performance of the functions of collecting, processing, displaying, recording information on oil accounting and control of operating modes C IQN (SIKNS).
