摘要

A utility model may be used in the oil industry, for example to control flow rate of oil wells. The structure of the proposed system includes a high frequency probe comprising two coaxially arranged on an insulating tube high frequency resonator, each of which represents a short-circuited zigzag conductor is provided with two mutually orthogonal inputs-pin, limiting coil and narrowly-separating coil, the Coriolis flowmeter with electronic flow converters and the density, pressure and temperature sensors, the evaluating and control unit, with high gene Rathore, controlled switch, the controller of flow regimes of gas-liquid stream, the first and second controllers calibration of the Coriolis flowmeter, the two inputs of the amplifier, and four and eight transmit path dividing capacitors. Utility model allows using the method of radiowave RF sensing controllable flow in two mutually orthogonal directions to measure the relative volume content of its components, based on the method autocorrelation measurement speed to determine the speed of the controlled flow and using a Coriolis flowmeter electronic flow transducers and density and calibration controller , to measure the mass flow and density controlled environment. The obtained data about the relative volume fraction of flow components of its velocity, mass flow rate and density of the controlled environment allows to obtain a computationally complex control block proposed exploded reliable information about a mass flow rate of gas-liquid flow. To improve the accuracy of the information obtained in the mode of the controller analyzes the actual flow regime controlled environment, which makes it possible to reliably determine the exploded mass flow even at a substantially unsteady flow, and applied in a complex method of mutually orthogonal sensing flow improves accuracy; measurements. Controllers calibrations proposed complex allow considering the received mode information from the controller about the actual flow controlled mode select from arrays calibrations stored in the memory of each of these controllers, the calibration of the Coriolis flowmeter, which corresponds to the given mode. Selection reliable calibration enables to make accurate measurements of mass flow and density controlled environment at substantially even during transient inhomogeneous liquid flow. Obtained in the evaluating and control unit of the proposed complex collection of reliable data on the mode of flow, velocity, mass flow rate, density, pressure and temperature of gas-liquid flow accurately and reliably calculate an exploded mass flow of the controlled medium, and to transmit the received information to external systems interacting.
