It is only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to this application.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0044] Principle of ultrasonic flowmeter: Based on the fact that the propagation speed of ultrasonic waves in a flowing medium is equal to the vector sum of the average flow velocity of the measured medium and the velocity of sound waves in a stationary medium. An ultrasonic flowmeter mainly consists of an ultrasonic transmitting transducer and a receiver. The transducer converts electrical energy into ultrasonic energy and emits it into the measured fluid. The ultrasonic signal received by the receiver is amplified by an electronic circuit and converted into an electrical signal representing the flow rate, which is supplied to a display and integrating instrument for display and integration. With its non-contact measurement method, the ultrasonic flowmeter can be easily installed without cutting off the pipeline, making it particularly suitable for systems that do not allow interruption of operation. And because there are no moving parts or flow obstructing devices inside it, it hardly causes any pressure loss to fluid transportation and will not cause the "cavitation" phenomenon due to pressure drop. This type of flowmeter is not only applicable to a variety of media, including liquids and gases, but also not affected by conductivity, making it an important supplement to electromagnetic flowmeters. In terms of accuracy, ultrasonic flowmeters perform excellently, especially in large-diameter pipelines where they can provide extremely accurate flow data. In addition, some types of ultrasonic flowmeters can also measure other parameters such as temperature and pressure simultaneously, further enhancing their practicality.

[0045] Ultrasonic flowmeters have a wide range of application fields. From monitoring water flow in water treatment plants and sewage treatment plants in the water treatment industry, to accurately measuring oil and gas in the oil and gas industry; from measuring heat energy in district heating systems in energy management, to optimizing the performance of HVAC systems in the construction industry; and then to ensuring accurate measurement of fluids in the chemical and pharmaceutical industries and meeting strict hygiene standards. With its versatility and high reliability, ultrasonic flowmeters play an important role in many industries.

[0046] See Figure 1 , which shows a schematic structural diagram of a flow detection device provided by an embodiment of the present application, including:

[0047] Support rod 6;

[0048] Slide rail 1, which is provided on the support rod 6;

[0049] Slider 2, which is arranged on the slide rail 1;

[0050] Detection component, part of the detection component is arranged on the slide rail 1 and part is arranged on the slider 2;

[0051] Signal transmission module 4, which is connected to the detection component.

[0052] In the above embodiments, the main structure of the flow detection device includes key components such as a support rod 6, a slide rail 1, and a slider 2. These components work together to ensure that the detection component can perform flow measurement flexibly and accurately under different environmental conditions. The support rod 6 serves as the main support structure of the entire device. It not only needs to have sufficient strength to bear the weight of other components but also requires good stability to ensure the accuracy during the measurement process. The design of the support rod 6 usually takes into account the actual usage on-site. For example, for easy carrying and installation, it is made of lightweight but strong materials, such as aluminum alloy or high-strength plastic, so that the operator can quickly set up and adjust the equipment on-site. The slide rail 1 is provided on the support rod 6. The design of the slide rail 1 needs to consider factors such as low friction, high wear resistance, and easy maintenance. The slider 2 is arranged on the slide rail 1. Its main function is to carry and fix some components of the detection component and change the distance from the first flow sensor 33 by moving along the slide rail 1. The design requirements of the slider 2 include good sliding performance to reduce friction, and it should be convenient for disassembly and installation to facilitate daily maintenance and calibration work. The detection component is designed in this application to be partially arranged on the slide rail 1 and partially on the slider 2. This layout allows the sensor to move along the slide rail as needed to adapt to different pipe diameters or measurement requirements. The signal transmission module 4 is one of the core components of the entire system, responsible for receiving data from the detection component and transmitting it to the host for processing. The signal lines connected from all sensors first access the signal transmission module, and then this module uniformly transmits them to the host. This design simplifies the line management and reduces the problem of messy wiring. The signal transmission module 4 is internally provided with a circuit board for processing and optimizing signal transmission to ensure the stability and reliability of data transmission. For easy carrying and on-site deployment, the signal transmission module 4 is designed to be relatively compact and occupy a small space.

[0053] The stability and firmness of the support rod 6 provide a solid foundation for the entire device, ensuring that this application can maintain high-precision measurements even in complex industrial environments. The design of the slide rail 1 ensures that the slider 2 can move smoothly and accurately along a predetermined path, which is crucial for ensuring the accuracy of the measurement. The presence of the slider 2 enables the detection component to flexibly adjust its configuration according to different measurement requirements, greatly expanding the application scope of this application. By installing the detection component on the slider 2, the distance between the detection components can be flexibly adjusted according to actual needs, so as to adapt to pipes of different diameters. This design improves the application scope and flexibility of this application. Moreover, the detection component integrates multiple sensors, enabling multiple parameter measurement tasks to be completed with one installation, reducing the workload of on-site operators, and improving the integrity and reliability of the data. The signal transmission module 4 can receive and process data from multiple sensors in real time and transmit it efficiently to the host computer, ensuring the timeliness and integrity of the data. The design of the built-in circuit board helps to filter out electromagnetic interference in the external environment, ensuring the quality of signal transmission, and thus improving the accuracy of the measurement results. Since all sensors are connected to the host computer 5 through the signal transmission module 4, during maintenance, only the status of this module needs to be checked, without having to check the connection of each sensor one by one, simplifying the maintenance process.

[0054] Furthermore, the device further includes:

[0055] A host computer 5, and the host computer 5 is connected to the signal transmission module 4.

[0056] In the above embodiment, the device further includes a host computer 5, and the host computer 5 is connected to the signal transmission module 4. This design allows the data collected by the detection component to be efficiently transmitted to the host computer 5 for analysis and processing. As the central processing unit, the host computer 5 is not only responsible for receiving data, but also capable of real-time monitoring and adjustment of various parameters generated during the flow measurement process. In addition, the host computer 5 is also equipped with a user interface, enabling the operator to conveniently view the test results and adjust the settings of the detection component as needed.

[0057] By connecting the host computer 5 to the signal transmission module 4, centralized management and processing of data are achieved, improving the working efficiency of this application and the accuracy of the measured data. The operator can intuitively understand the status of the flow detection through the host computer 5 and make corresponding adjustments quickly, which greatly simplifies the operation process, reduces the possibility of human errors, and at the same time improves the reliability and stability of the system.

[0058] Furthermore, the detection component includes:

[0059] A first sensor 31, and the first sensor 31 is arranged at the end of the slide rail 1;

[0060] The second sensor 32 is provided at the end of the slide rail 1, and the second sensor 32 and the first sensor 31 are located at the same end of the slide rail 1.

[0061] In the above embodiment, the detection assembly includes a first sensor 31 and a second sensor 32. The first sensor 31 is an ultrasonic thickness gauge sensor, and the second sensor 32 is an infrared temperature probe. They are both provided at the end of the slide rail 1 and are located at the same end.

[0062] The first sensor 31 is used to detect the thickness of the pipeline wall, and the second sensor 32 is used to detect the temperature of the fluid in the pipeline. The first sensor 31 and the second sensor 32 can also send the test results to the host through the signal transmission module 4 to provide basic data for subsequent flow calculation. The layout of placing the two sensors at the same end facilitates installation and maintenance and reduces the time cost of equipment debugging.

[0063] Furthermore, the detection assembly further includes:

[0064] A first flow sensor 33, which is provided on the slide rail 1;

[0065] A second flow sensor 34, which is provided on the slider 2.

[0066] In the above embodiment, the detection assembly includes a first flow sensor 33 and a second flow sensor 34. Both of them are ultrasonic flow sensors, which can measure the flow rate of the liquid in the pipeline and are respectively installed on the slide rail 1 and the slider 2 through brackets. This layout design not only ensures the stability and accuracy of the sensors but also allows users to flexibly adjust the distance between the two sensors according to specific measurement requirements. Specifically, the first flow sensor 33 serves as a fixed measurement point, providing a stable reference position, while the second flow sensor 34 moves along the slide rail 1 through the slider 2, enabling the detection assembly to adapt to pipelines of different diameters. Simply adjusting the position of the slider 2 can change the distance between the two sensors, thus meeting the requirements of various complex measurement tasks.

[0067] Adopting this adjustable design greatly enhances the flexibility and adaptability of this application, enabling it to be widely used in pipeline measurement tasks of various sizes. Whether it is a small-diameter fine pipeline or a large-diameter industrial conveying pipeline, this application can achieve accurate flow measurement through simple operations. In addition, this design also significantly simplifies the on-site installation and debugging process, reducing the additional workload and time cost caused by pipeline size changes. Operators can quickly adjust the position of the sensors according to actual needs without reconfiguring the entire measurement system, greatly improving work efficiency.

[0068] Further, the first flow sensor 33 is detachably connected to the slide rail 1, and the slider 2 is detachably connected to the slide rail 1.

[0069] In the above embodiment, the first flow sensor 33 is detachably connected to the slide rail 1, and at the same time, the slider 2 is also detachably connected to the slide rail 1. This design allows users to flexibly adjust the position and configuration of the sensor according to actual measurement requirements. The first flow sensor 33 can be easily detached from the slide rail 1 by fasteners and reinstalled at the desired position. Similarly, the slider 2 can be conveniently moved along the slide rail 1 and fixed at any specified position to adapt to different measurement scenarios and pipe sizes.

[0070] The design of the detachable connection significantly improves the flexibility and adaptability of the device, enabling the operator to quickly adjust the arrangement of the sensors according to specific measurement tasks. For example, when facing pipes of different diameters, the distance between the first flow sensor 33 and the second flow sensor 34 can be quickly changed to ensure measurement accuracy. In addition, this design also simplifies the maintenance and calibration process of the equipment because the sensor and the slider 2 can be detached separately for inspection, repair or replacement without moving the entire device. This not only reduces the downtime but also lowers the maintenance cost and improves the overall working efficiency. In this way, users can enjoy higher operation convenience and system reliability while maintaining high measurement accuracy.

[0071] Further, the device further includes:

[0072] A limit block 11, which is provided on the slide rail 1 and is used to limit the movement of the slider 2.

[0073] In the above embodiment, the device further includes a limit block 11 for limiting the movement range of the slider 2 to prevent the slider from exceeding the safe movement range due to misoperation or mechanical failure, thereby protecting the equipment from damage.

[0074] The presence of the limit block 11 provides physical safety protection for the slider 2, avoids hardware damage caused by excessive movement, extends the service life of the equipment, and ensures the safety of the operator.

[0075] Further, the device further includes:

[0076] A scale, which is provided on the slide rail 1.

[0077] In the above embodiment, this application is equipped with a scale directly provided on the slide rail 1 to facilitate the operator to accurately adjust the position of the slider 2 to ensure that the distance between the two flow sensors meets the measurement requirements.

[0078] The addition of the ruler improves positioning accuracy, allowing operators to quickly and accurately adjust the sensor position according to specific needs, thereby improving the efficiency and accuracy of the entire measurement process.

[0079] Furthermore, the device also includes:

[0080] A first signal line, one end of which is connected to the detection component, and the other end of which is connected to the signal transmission module 4;

[0081] A second signal line, one end of the second signal line is connected to the signal transmission module 4 , and the other end of the second signal line is connected to the host 5 .

[0082] In the above embodiment, in order to realize effective data transmission, a first signal line and a second signal line are also included, the former connecting the detection component with the signal transmission module 4, and the latter connecting the signal transmission module 4 with the host 5. These two groups of signal lines ensure that the data obtained from the detection component can be transmitted to the host 5 for processing without loss.

[0083] Data transmission is carried out through a dedicated signal line, ensuring the stability and accuracy of data transmission, avoiding possible interference problems in wireless transmission, and providing strong support for high-precision flow measurement.

[0084] The following preparations are required before using this application to perform flow testing:

[0085] Step 1: Before starting the flow meter host 5, check whether the flow meter sensor is fully connected to the host 5 to avoid a false connection.

[0086] Step 2: Check whether the first flow sensor 33 and the second flow sensor 34 are stably and firmly fixed on the support rod 6; check whether the positions of the first flow sensor 33 and the second flow sensor 34 are at the initial positions (the initial position of the first flow sensor 33 is the 0 scale of the ruler, and the initial position of the second flow sensor 34 is that the sliding slider 2 is close to the lower end of the bracket of the first flow sensor 33); check whether there is dirt and attachments on the surface of the flow meter sensor, and wipe the sensor surface.

[0087] Step 3: Check whether the first sensor 31 and the second sensor 32 are firmly fixed on the scale; check whether there is dirt and attachment on the surface of the first sensor 31 and the second sensor 32, and wipe the sensor surface.

[0088] Step 4: Check whether the joints between the sensor, signal transmission module 4 and the signal line are intact.

[0089] Step 5: Apply a proper amount of coupling agent on the contact surfaces of the first flow sensor 33, the second flow sensor 34 and the first sensor 31 along the longitudinal direction. No air or bubbles should be allowed between the sensor surface and the pipe wall.

[0090] Step 6: Inspect the outer wall of the pipeline where the flowmeter is to be installed, remove rust and other coatings to ensure optimal acoustic coupling with the sensor.

[0091] See Figure 2 , which shows a schematic flow chart of a flow detection method provided by an embodiment of the present application, including:

[0092] Bring the detection component into contact with the outer wall of the pipeline to be measured, start the basic information test through the host, and the detection component sends the basic information test result to the host through the signal transmission module. The basic information test result includes the wall thickness of the pipeline and the fluid temperature inside the pipeline, and input the preset pipeline information into the host;

[0093] Select the acoustic path factor on the host. The acoustic path factor includes the diagonal mode and the reflection mode, and determine the layout method of the detection component according to the acoustic path factor and perform flow detection.

[0094] In the above embodiment, the flow detection method first requires the operator to bring the detection component into contact with the outer wall of the pipeline to be measured and start the basic information test through the host. This step involves measuring the basic physical parameters of the pipeline, including the wall thickness of the pipeline and the fluid temperature inside the pipeline. The basic information test result will be sent to the host through the signal transmission module. Subsequently, the operator directly inputs key information such as the outer diameter, material, test medium type, lining material, and surface roughness of the pipeline into the host. These data are crucial for subsequent flow calculations because they directly affect the propagation characteristics of sound waves in the fluid and the optimal layout method of the sensor. The host then performs further data processing and analysis based on this information.

[0095] This host-based basic information test process ensures that the wall thickness of the pipeline and the fluid temperature inside the pipeline can be accurately obtained, reduces the workload of the operator, and lays a solid foundation for subsequent accurate flow measurement. The host's centralized data processing ability enables complex calculations to be executed efficiently, reducing the possibility of human error. In addition, the automated data acquisition process simplifies the operation steps, improves work efficiency, and also ensures the consistency and reliability of the data.

[0096] Further, the method further includes:

[0097] The layout method of the detection component corresponding to the diagonal mode is: Remove the second flow sensor from the slider, and arrange the second flow sensor on the opposite side of the outer wall of the pipeline to be measured according to the layout distance between the second flow sensor and the first flow sensor calculated by the host;

[0098] The arrangement method of the detection component corresponding to the reflection mode is as follows: The host computer calculates the arrangement distance between the second flow sensor and the first flow sensor, and the slider drives the second flow sensor to move along the slide rail to a predetermined position.

[0099] In the above embodiment, a further method includes selecting an acoustic path factor to determine the specific arrangement method of the detection component. The acoustic path factor includes a diagonal mode or a reflection mode. In the diagonal mode, the second flow sensor needs to be removed from the slider and installed at the opposite position of the pipeline under test according to the distance calculated by the host computer; while in the reflection mode, the sensor spacing calculated by the host computer determines the position where the slider should move so that the second flow sensor can reach the predetermined location along the slide rail. The selection of these two modes depends on the specific pipeline conditions and the required measurement accuracy.

[0100] The flexible selection mechanism of using the diagonal mode or the reflection mode greatly enhances the adaptability of this application, enabling it to cope with various complex on-site environments and different pipeline specifications. The diagonal mode is suitable for pipelines with a larger diameter and can provide a wider coverage range, while the reflection mode is more suitable for small-diameter pipelines, and it can optimize the measurement accuracy by adjusting the sensor spacing. Such a design not only improves the flexibility and accuracy of the measurement but also enables the smooth completion of even challenging measurement tasks. In this way, users can select the most suitable detection scheme according to the actual situation, thereby obtaining more reliable and accurate flow data.

[0101] The specific steps for applying this application to perform a flow test are as follows:

[0102] The first step: Press the contact surfaces of the sensors tightly against the outer wall of the pipeline under test, select the measurement channel on the instrument host and start the test. The first sensor and the second sensor start to work, and send the test results to the host through the signal transmission module. Set the outer diameter of the pipeline, pipeline material, test medium, pipeline lining, and pipeline roughness on the instrument host.

[0103] The second step: Select the acoustic path factor on the instrument host. The two acoustic path factors of the reflection mode and the diagonal mode can be selected. Different acoustic path factors correspond to two different arrangement methods of the ultrasonic flowmeter sensors. The two flow sensors in the reflection mode are arranged on the same side of the pipeline, and the two flow sensors in the diagonal mode are arranged on the opposite sides of the pipeline.

[0104] The third step: After confirming the acoustic path factor, click continue on the host. If the diagonal mode was selected in the previous step, the sensor needs to be removed from the bracket of the second flow sensor, manually measure the arrangement distance from the first flow sensor, and place the second flow sensor at the correct position on the opposite side of the pipeline; if the reflection mode was selected in the previous step, the slider will automatically move along the slide rail to the calculated position.

[0105] Other precautions for testing: (1) An arrow mark is engraved on each sensor. If the arrow directions on the two ultrasonic flow sensors are the same, it indicates that the sensors are correctly installed, and the first signal line should show the opposite direction. (2) A certain pressure is required to fix the installation of the ultrasonic sensor. (3) When the sensor is installed on a vertical pipe and the position of the main unit is lower than the measured pipeline, it is recommended to move the cable above the sensor to below the main unit to protect it from mechanical stress.

The present application integrates an ultrasonic flow sensor, an ultrasonic thickness measurement sensor, and an infrared temperature measurement probe, and can simultaneously measure multiple parameters such as liquid flow rate, pipeline wall thickness, and fluid temperature in one installation, which not only reduces the workload of on-site operators, but also improves the integrity of data and the reliability of measurement results. The slider and the sensor bracket adopt a quick-release design, which is convenient for users to quickly replace or adjust the position of the sensor, greatly improving the convenience and flexibility of operation.
