Research and Production Enterprise Electrotech LLC Izhevsk About company Research and Production Enterprise Electrotech is developer and manufacturer of Well Cementing Process Control System SKCS-01 The company has been operating for fifteen years, while system SKCS-о1 has been supplied for more than ten years. SKCS-01 System SKCS-01 is used in oil and gas industry for the operations as follows: • well cementing, • well major workover, and • cement squeeze. System SKCS-01 may be used for various processes where fluids of different density are pumped. Parameters System SKCS-01 makes measurement, recording, and monitoring of the parameters as follows: • Density from 800 to 2,400kg/cu.m, • Flow rate up to 180cu.m/h, • Pressure up to 40MPa, and • Temperature from -40 to +80°C. Basic package of system SKCS-01 Vibration densitometer Density is measured by means of vibration method. Fluid fills two tubes which execute induced oscillation relative to each other in resonant mode with amplitude of less than 0.5mm. Resonance frequency depends on weight of tubes filled with the fluid. Electromagnetic flow meter Principle of operation: Measurement of electromotive force (EMF) generated during flow of electrically conducting fluid in magnetic field. Vibration flow meter (Coriolis) Advanced device for measurement of flow rate and density of fluid flow. It does not depend on flow electrical conductivity. It is of straight-tube design working based on vibration method. Design of Coriolis flow meter: Two parallel tubes which execute relative transverse oscillations in horizontal plane of less than 0.5mm in amplitude. Thermal box ensures stable operation conditions of the device. Principle of operation: Resonance transverse oscillations are excited in the tube. Fluid flowing along the tube breaks symmetry of oscillations relative to tube center. Displacement transducers, mounted at side areas, record the resulting phase difference. The higher fluid velocity, the more phase difference. Advantages of straight-tube Coriolis flow meter • Straight tubes ensure high resistance to abrasive action of flow of the pumped fluid which provides operational integrity and safe operation in high pressure lines. • Oscillation amplitude is no more than fractions of millimeter. Flow passes through the device with little to no disturbance. • Simultaneous measurement of flow rate and density regardless of electrical conductivity of the fluid. Straight-tube measurement elements inside fluid flow. devices without moving In order to increase sensitivity to change of flow rate of the pumped fluid, Research and Production Enterprise Electrotech has been developing Coriolis flow meters with slightly-bent tubes. Internal design of Coriolis flow meter of increased sensitivity. Features of SKCS-01 devices • • • • Direct flow design, Operation in high pressure line, Pressure-tight, Impact-resistant. System SKCS-01 • Electric power supply: operating voltage of 12V or 24V. Operation from commercial network of 220V. • Power reserve from several voltage sources. • Consumed power of the whole system is no more than 300W. • Protection from short-term power failure by means of smallcapacity battery backup (for example, during car engine start).
