DETAILED DESCRIPTION
[0027] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
[0028] It should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the utility model described here can be implemented in an order other than those illustrated or described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.
[0029] It should be noted that in actual field applications, the flow of the medium in a container such as a pipe will generate eddies, which move synchronously with the medium. During this process, one or more eddies located on the same cross section of the container will cause the container to vibrate at different points in the container, and the characteristics of these container vibrations are basically the same. Based on this, the non-contact medium flow meter proposed in the utility model can determine the medium flow rate by detecting the speed of change of the container vibration caused by one or more eddies located on a certain cross section of the container, and then analyze the medium flow rate.
[0030] The non-contact medium flow meter proposed in the utility model can be applied to the flow measurement scenario of high-temperature medium. In the flow measurement scenario of high-temperature medium, the non-contact medium flow meter is not affected by the heat conducted by the container, which is beneficial to the working time of the medium flow meter.
[0031] In the utility model, by installing the array measuring component on the container in a non-contact manner, multiple beams of measurement signals can be emitted to multiple cross-sections on the container and / or adjusters arranged at the cross-sections at various times, and analysis signals formed after each beam of measurement signals hits the outer wall of the container and / or the adjuster are received. Then, the control component can detect the container vibration caused by one or more eddy currents at multiple cross-sections on the container at various times according to the corresponding measurement signals and analysis signals, and can calculate the changing speed of the eddy current in the container according to the spacing between the cross-sections where two consistent container vibrations are located and the time interval between the two consistent container vibrations, so as to calculate the medium flow rate of the medium in the container according to the changing speed and the cross-sectional size of the container. In this way, the medium in the container is measured non-contactly by the medium flow meter, so that the medium flow meter is not affected by the medium temperature, which is beneficial to the working time of the medium flow meter.
[0032] The present invention will be described in detail below in conjunction with various embodiments.
[0033] Embodiment 1
[0034] According to an embodiment of the utility model, an embodiment of a non-contact medium flow meter is provided.
[0035] Figure 1 is a schematic diagram of an optional non-contact medium flow meter according to an embodiment of the utility model, such as Figure 1 As shown, the non-contact medium flow meter 1 includes: an array measuring component 10 and a control component 20, and a connection is established between the array measuring component 10 and the control component 20.
[0036] Among them, the array measuring component 10 is non-contact with the medium in the container 2, and is arranged outside the container 2, and is used to transmit multiple beams of measurement signals to multiple cross-sections on the container 2 at various times. Multiple beams of analysis signals formed between each beam of measurement signals and multiple cross-sections on the outer wall of the container 2 and / or between the adjusters 30 arranged at multiple cross-sections on the container 2 are received by the array measuring component 10.
[0037] The control component 20 is connected to the array measurement component 10, and is used to detect the container vibration information at multiple cross sections on the container 2 at each moment based on each beam of measurement signals and the analysis signal corresponding to the measurement signal, and detect the medium flow rate of the medium in the container 2 based on the container vibration information at multiple cross sections at each moment.
[0038] In the embodiment of the utility model, the array measuring component 10 and the control component 20 can establish a wireless communication connection or a wired communication connection.
[0039] In the embodiment of the utility model, the array measuring component 10 in the non-contact medium flow meter 1 can be non-contact mounted with the container 2, and can collect measurement data (e.g., signal data, capacitance data) corresponding to multiple cross sections at various times on the container 2. The control component 20 can establish a communication connection with the array measuring component 10 in advance to receive the measurement data collected by the array measuring component 10 through the communication connection. The control component 20 can detect the container vibration caused by one or more eddies at multiple cross sections on the container at various times based on the received measurement data, and as the medium continues to flow, the control component 20 can detect another recent container vibration that is consistent with the container vibration caused by one or more eddies at a certain cross section of the container at a certain time.
[0040] In the embodiment of the utility model, the control component 20 can also calculate the changing speed of the eddy current in the container by detecting the spacing and time interval between two times of the same container vibration at the container cross section, and the changing speed is the medium flow rate, and then calculate the medium flow rate of the medium in the container according to the medium flow rate and the cross-sectional size of the container.
[0041] In the embodiment of the utility model, an adjuster 30 may be provided in the non-contact medium flow meter 1 and fixed on the container 2 to enhance the strength of the analysis signal, thereby improving the measurement accuracy of the non-contact medium flow meter 1.
[0042] In an optional embodiment, the container vibration information includes at least one of the following: frequency component, amplitude, and phase.
[0043] In another optional embodiment, the medium flow rate includes at least one of the following: volume flow rate, mass flow rate, and weight flow rate.
[0044] In the embodiment of the utility model, the medium flow rate is determined by detecting the change speed of the container vibration caused by one or more eddies located on a certain cross section of the container 2 by the non-contact medium flow meter 1. Assuming that the container vibration detected at the cross section A at the current moment is consistent with the container vibration detected at the cross section A' at the next moment, the medium flow rate (v) can be calculated by the time interval Δt between the current moment and the next moment and the distance x between the cross section A and the cross section A', that is,
[0045] In some optional embodiments, the medium flow rate may be a volume flow rate, a mass flow rate, a weight flow rate, etc. After the medium flow rate is calculated, the medium flow rate may be calculated by the following formula:
[0046] Volume flow rate (Q) = medium flow velocity (v) × pipe cross-sectional area (A);
[0047] Mass flow rate (M) = medium density (ρ) × volume flow rate (Q) = medium density (ρ) × medium flow velocity (v) × pipe cross-sectional area (A);
[0048] Weight flow rate (G) = medium gravity (γ) × volume flow rate (Q) = medium density (ρ) × gravitational acceleration (g) × volume flow rate (Q) = gravitational acceleration (g) × mass flow rate (M).
[0049] In the above formula, the pipe cross-sectional area (A) can be obtained in advance by measuring the cross-sectional dimensions of the container, and the medium density (ρ) can be obtained according to the type of medium. For example, if the medium is water, the density of water can be 1000kg / m 3 (kilograms per cubic meter), the acceleration due to gravity (g) is usually 9.81m / s 2 (meters per square second).

[0058] In the embodiment of the utility model, the array signal measurement component 10a may further include: an adjuster 30, each adjuster 30 corresponds to a measurement unit 10a1, so as to enhance the strength of the analysis signal.
