- the specified signal from the output of the first transceiver path 30 is fed to the first input of the mode controller 20, in which a preliminary classification analysis of the informative parameters of the incoming signal is performed.
- the purpose of the preliminary classification analysis is to roughly classify the flow patterns of the controlled flow as one of the “steady” and “steady” modes, with the subsequent refinement of the choice of the sub-mode of the established mode, for example, one of the sub-modes: “y became - oil”, “y became” - water , “Y becoming - gas”, “stationary - oil-gas”, established - oil-gas ”,“ stationary - gas-water ”, established - oil-gas, or non-oil non-stationary - oil-gas ”, etc.
- the code signal corresponding to the selected submode comes from the output of the mode controller 20 to the input of the delay unit 21; if there is a non-zero delay command at the control input of this unit (“ ⁇ t” ⁇ 0), the signal is delayed in it by the time ⁇ t, after which it is transmitted through one of the inputs of the computing and control unit 15 to the corresponding input of the calculator 16, in which from the group of control algorithms component-wise composition, an algorithm is selected that corresponds to the received submode code.

- the “second output” command is generated in the control unit 17, which comes from one of the outputs of this unit through the corresponding output of the computing and control unit 15 to the control input of the managed switch 19, as a result of which the high-frequency signal generated by the controlled high-frequency generator 18 and transmitted from its output to the input of the managed switch 19, switches to the second output of the given switch, from where it goes to each of the inputs of the second transceiver paths 31, 32 and 3 3.
- a high-frequency signal is transmitted through the corresponding input amplifier 22 to the second input-output 6 of each of the resonators 2, 3, 4.
- the specified signal is fed to the second input of the mode controller 20, in which, based on an analysis of the informative parameters of the incoming signal, the previously established sub-mode of the monitored stream is specified and the code signal corresponding to the specified sub-mode is transmitted through the delay unit 21 (with a time delay ⁇ t) through one of the inputs of the control computer block 15 to the corresponding input of the calculator 16, where based on the analysis of the signal received by the calculator 16 from the additional input-output 6 of the third resonator 4 through the second transceiver path 33, if necessary, the previously selected algorithm is refined and the previously calculated instantaneous values are corrected relative volume fractions of Vi, V 2 and V 3 of each of the three components of the controlled flow.
- the autocorrelation method is selected.
- information on the motion of the natural flow label, or information on the motion of the local inhomogeneity of the flow, or information on the motion of the local flow feature is used.
- the mode controller 20 when the mode controller 20 has established a mode of essentially unsteady movement of the controlled flow, received at the input of the calculator 16 from the first I / O 5 and the second I / O 6 of the first and second resonators 2 and 3, respectively, the previously described informative signals are continuously recorded in the memory of the calculator 16 in the form of temporary implementations of each of these signals.
- informative signals resonators 2 and 3 may be used, for example, depending on the time t amplitudes: I pez i (t), I pez 2 (t), I pe ss (t) close to the previously mentioned first, second and third resonant frequencies Fresi, Fp 632 , Fp ez s, respectively.
- the bias time is determined in the calculator 16, and since this time is equal to the time interval ⁇ running by the natural mark of the flow — its stable fluctuation — some fixed length of the radio wave sensor, taken as the base length L 0 , the speed is calculated W controlled flow in accordance with the expression
- L 0 is the base length equal to the axial distance between the geometric centers of the first and second resonators 2 and 3, respectively.
- the obtained velocity value W is used in calculator 16 to calculate the instantaneous values of the component-wise volumetric flow rates Qi, Qg 5 Qc of each of the three components of the gas-liquid flow, as well as to calculate the delay time ⁇ t and transmit the corresponding ⁇ t command to the control input of the delay unit 21.
- Command " ⁇ t" is designed to synchronize the moment of use in the calculator 16 of the algorithm corresponding to the code on the mode of the controlled flow, with the time t 2 getting into the center of the second resonator 3 of that region th stream, which at the moment t ⁇ was located in the center of the third resonator 4 and was subjected to radio wave sounding in it, while
- L is the axial distance between the geometric centers of the second and third resonators 3, 4, respectively (see Figure 1).
- the mode controller 20 determines the steady-state movement of an almost uniform controlled flow, in which there are no local, pronounced fluctuations in the component composition in the controlled medium, the determination of the velocity W by the above method may turn out to be unreliable.
- a reliably controlled flow feature in the proposed system not a local fluctuation of the component composition of the flow is used, but a local peculiarity of the flow, characterized by a substantially different ratio of the informative signals of the resonators 2 and 3 obtained by mutually orthogonal radio wave sounding of the controlled medium.
- the mutually orthogonal sounding method allows fixing such local features of an almost uniform steady flow, as, for example, local axial flow asymmetry, local helical flow swirling, concentrated helicoidal swirling of the flow, local turbulence and other local features that are not detected in principle with unidirectional sounding.
- the code corresponding to the refined submode is transmitted to the calculator 16, and in this calculator, the algorithm corresponding to the obtained code is selected from the group of algorithms “Speed calculation”.
- the time realizations of the relations of each of the signals generated on the first input-output 5 of the first resonator 2 and on the first input-output 5 of the second resonator 3 are processed, respectively, to the signal generated on the second input-output 6 of the first resonator 2 and to the signal generated at the second input-output 6 of the second resonator 3.
- the mutual correlation function of their time realizations is determined and the shift time of the realizations at which this function experiences a maximum is found.
- this time is equal to the time interval ⁇ running by the natural mark of the flow - its local feature, characterized by a significantly different ratio of the signals received during mutually orthogonal sounding of the controlled medium, the base length L 0 .
- the speed of the controlled flow in this case, as before, is
- V3 of the components of the controlled flow allows calculating the component-wise volumetric flow rate Q 1 Q 2 , Q 3 of each of the three components of the gas-liquid medium:
- the signals about the instantaneous values of pressure and temperature of the controlled medium supplied to the corresponding inputs of the calculator 16 from the sensor output are taken into account pressure 36 and temperature sensor output 37, and stored in the memory of the calculator 16, data about the nominal densities pi, p 2, ps of each of the three komponentov.Informatsiya exploded volume of Flow rate and, if necessary, - a exploded mass flow controlled stream may be transmitted from the calculator 16 to exchange information line 38 to external systems.
- the problem solved by the proposed invention which consists in increasing the reliability and accuracy of measuring the component flow rate at two extreme flow regimes of a controlled environment: substantially unsteady and fully steady flow, is solved by using the following new technical solutions in the proposed system: firstly, - due to the use of preliminary analysis of the flow regime in the mode controller 20 using the resonator 3, and secondly, due to the use of two different directions radio-frequency sounding using two mutually orthogonal I / O 5 and 6 and a controlled switch 19 and, thirdly, due to the identity and mutual symmetry of the resonators 2, 3, 4 and their working elements, such as restrictive and restrictive-separation turns 11 and 12.
