Description

Technical Field

[0001] This utility model relates to the field of flow meter technology, and in particular to a flow meter with a data collector. Background Technology

[0002] Flow meters are widely used in various industrial scenarios, and with the development of IoT technology in the field of flow metering, remote data acquisition has become an important direction for the intelligent upgrading of flow meters.

[0003] For example, the volume corrector for gas flow meters disclosed in patent number CN202223227321.4 is a comprehensive corrector capable of acquiring flow, pressure, and temperature signals and performing flow correction operations. However, its components and circuit design are complex, and it requires the installation of pressure and temperature sensors within the flow meter, resulting in high production costs for both the flow meter and the corrector. In the actual market, some customers do not require such comprehensive metering correction functions; they only need to collect and transmit flow meter counting information to meet their needs.

[0004] Based on this, the applicant is considering designing a flow meter with a simplified structure and controllable cost, equipped with a data collector. Utility Model Content

[0005] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is: how to provide a flow meter with a simplified structure and controllable cost that includes a data collector.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A flow meter with a data collector includes a flow meter body, a counter structure installed inside the flow meter body, and a data collector. The data collector includes a housing and a data acquisition motherboard installed therein. The data acquisition motherboard is communicatively connected to the counter structure of the flow meter body and is used to collect and send the counting information of the counter structure.

[0008] The working principle and advantages of a flow meter with a data collector in this technical solution are as follows:

[0009] When the flow meter is working, liquid or gas flows through the flow meter body, driving the internal counter structure to count and record relevant flow information. The main board communicates with the counter structure, enabling real-time acquisition of the counter's count information. The acquired data can be transmitted to remote monitoring centers, cloud servers, or local host computers via its own transmission function, allowing staff to remotely monitor and analyze the flow. Compared to previous fully functional correctors, this solution eliminates complex pressure sensors, temperature sensors, and corresponding complex circuit designs for flow correction, retaining only the core functional module for acquiring and transmitting count information. The overall structure is simpler, the cost is lower, and the assembly difficulty and error rate during production are reduced, while also reducing the complexity and cost of later maintenance.

[0010] Furthermore, the counter structure includes a magnetic induction device that is communicatively connected to the acquisition motherboard.

[0011] Furthermore, the flow meter body includes a housing, the counter structure is fixedly installed inside the housing, and a connector is embedded in the side wall of the housing. The connector is connected to the magnetic induction device through a wire.

[0012] Furthermore, the data collector includes a data cable, one end of which extends into the housing and is connected to the data acquisition motherboard, and the other end extends out of the housing and is connected to a connector that is plugged into the connector.

[0013] Furthermore, the connector is an aviation plug.

[0014] Furthermore, the housing includes a detachably connected upper cover and a lower cover, and the acquisition motherboard is installed inside the upper cover and the lower cover.

[0015] Furthermore, the upper cover is provided with a display screen that is communicatively connected to the acquisition motherboard. The display screen is used to display the counting information acquired by the acquisition motherboard. The upper cover is also provided with buttons for controlling the display screen.

[0016] Furthermore, a fixing frame is provided inside the lower cover, and a battery that supplies power to the acquisition motherboard is installed inside the fixing frame.

[0017] Furthermore, the data acquisition unit also includes an external antenna electrically connected to the acquisition motherboard, and the external antenna is fixedly connected to the housing.

[0030] Refer to together Figures 1 to 3This embodiment provides a flow meter with a collector 200, including a flow meter body 100, a counter structure 110 installed inside the flow meter body 100, and a collector 200. The collector 200 includes a housing and a collector motherboard 230 installed therein. The collector motherboard 230 is communicatively connected to the counter structure of the flow meter body 100 and is used to collect and send the counting information of the counter structure 110.

[0031] In this embodiment, when the flow meter is working, liquid or gas flows through the flow meter body 100, driving the internal counter structure 110 to count and record relevant flow information. The acquisition motherboard 230 is connected to the counter structure 110 and can collect the counting information generated by the counter in real time. The collected data can be transmitted to a remote monitoring center, cloud server, or local host computer through its own transmission function, so that staff can remotely monitor the flow and analyze the data. Compared with the previous fully functional correction instrument, this solution directly eliminates the complex pressure sensor, temperature sensor, and corresponding complex circuit design for flow correction, and only retains the core functional module for collecting and transmitting counting information. The overall structure is simpler, reducing the assembly difficulty and error rate in the production process, and reducing the complexity and maintenance cost in the later stage.

[0032] Preferably, such as Figure 3 and Figure 4 As shown, the counter structure 110 includes a magnetic induction device 111 that is communicatively connected to the acquisition motherboard 230. The magnetic induction device 111 can sense the flow rate change within the flow meter body 100 and convert it into an electrical signal, which is then transmitted to the acquisition motherboard 230. This ensures that the counting information can be transmitted to the acquisition motherboard 230 in real time and accurately, thereby realizing the effective acquisition and transmission of flow meter counting information and meeting the needs of remote data monitoring and analysis. Specifically, the counter structure 110 of this solution can adopt the counter structure 110 in the prior art, such as the counter structure 110 with multiple sampling methods disclosed in patent number CN201822009545.5, which describes the working principle of the counter structure 110. The signal generated by the magnetic induction device 111 can be imported into the acquisition motherboard 230 through the communication connection with the acquisition meter.

[0033] Preferably, such as Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, the flow meter body 100 includes a cover 120, and a counter structure 110 is fixedly installed inside the cover 120. A connector 251 is embedded in the side wall of the cover 120. The connector 251 is connected to the magnetic induction device 111 through a wire (not shown in the figure). The cover 120 on the flow meter body 100 can protect the counter structure 110 from the influence of external environmental factors. The connector 251 is embedded in the side wall of the cover 120. The connector 251 is connected to the magnetic induction device 111 through a wire, so that the signal generated by the magnetic induction device 111 can be stably transmitted to the connector 251 through the wire. The connector 251 facilitates connection with the external data acquisition device 200 and facilitates the maintenance and replacement of the equipment.

[0034] Preferably, such as Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the data collector 200 includes a data cable 250. One end of the data cable 250 extends into the housing and connects to the data acquisition motherboard 230, while the other end extends out of the housing and connects to a connector 251 that plugs into the connector 251. The data cable 250 connects to the connector 251 on the cover 120 via the connector 251, enabling the data acquisition motherboard 230 to connect to the counter structure 110, ensuring the stability and reliability of data transmission. The data acquisition motherboard 230 can receive counting information from the magnetic induction device 111 in real time and transmit the information to the inside of the data collector 200 for processing and transmission via the data cable 250, simplifying the connection and disassembly process of the device and improving the maintainability and scalability of the flow meter.

[0035] Preferably, such as Figure 6 As shown, the aforementioned connector 251 is an aviation connector 121. The aviation connector 121 has good reliability, stability, sealing, and vibration resistance, and can effectively prevent the influence of external factors such as dust and moisture on the connection part. At the same time, the standardized design of the aviation connector 121 makes it have good compatibility and versatility, which facilitates integration and docking with other devices. In the connection between the flow meter body 100 and the data collector 200, the use of the aviation connector 121 can ensure the stability and reliability of data transmission and improve the overall performance and stability of the equipment.

[0036] Preferably, such as Figure 5As shown, the housing includes a detachably connected upper cover 210 and a lower cover 220, and the acquisition motherboard 230 is installed inside the upper cover 210 and the lower cover 220. By removing the upper cover 210 and the lower cover 220, the acquisition motherboard 230 can be easily installed, debugged or replaced, which not only improves the maintainability of the equipment, but also facilitates modular assembly during the production process and improves production efficiency. Specifically, a sealing structure is provided between the detachable upper cover 210 and the lower cover 220 to prevent the external environment from adversely affecting the acquisition motherboard 230 and improve the stability and service life of the data collector 200.

[0037] Preferably, such as Figure 5 As shown, the upper cover 210 is equipped with a display screen 211 that is communicatively connected to the acquisition motherboard 230. The display screen 211 is used to display the counting information acquired by the acquisition motherboard 230. The upper cover 210 is also equipped with a button 212 for controlling the display screen 211. The display screen 211 allows users to intuitively view the flow meter's counting data on-site without relying on remote devices or complex software interfaces. Users can also easily operate the display screen 211 through the control button 212, such as turning on the display screen 211, switching display modes, and adjusting display parameters, thereby improving operational convenience.

[0038] Preferably, such as Figure 5 As shown, a mounting bracket 241 is provided inside the lower cover 220, and a battery 242 that powers the acquisition motherboard 230 is installed inside the mounting bracket 241. Installing the battery 242 inside the mounting bracket 241 can effectively prevent poor contact or damage to the battery 242 due to vibration or movement during use, thereby improving the stability and safety of the battery 242. By powering the acquisition motherboard 230 with the battery 242, the acquisition device 200 is not limited by an external power source during use, thus improving the flexibility and applicability of the device.

[0039] Preferably, such as Figure 2 and Figure 5 As shown, the data collector 200 also includes an external antenna 221 electrically connected to the data acquisition motherboard 230. The external antenna 221 is fixedly connected to the housing. The design of the external antenna 221 can effectively enhance the transmission capability of wireless signals, ensuring that the collected counting information can be stably and remotely transmitted to the remote monitoring center or receiving device. By placing the antenna outside the housing, the shielding effect of the housing on the signal can be avoided, improving the signal transmission and reception efficiency. The external antenna 221 can be adjusted and optimized according to the actual use environment and needs, such as selecting antennas with different gains or directions to adapt to various complex industrial environments and ensure the reliability of data transmission.

[0040] Preferably, such as Figures 1 to 3As shown, the housing is detachably connected to the flow meter body 100, and the housing and the flow meter body 100 are detachably connected via mounting bracket 260. When maintenance, upgrades, or replacements of the collector 200 are required, operators can easily remove the housing from the flow meter body 100 to perform the necessary operations, and then reinstall it to ensure the normal operation of the equipment. Through the detachable connection method, the collector 200 can be flexibly installed on different types of flow meter bodies 100 according to actual needs, improving the versatility and adaptability of the equipment. During transportation or storage, the collector 200 can be separated from the flow meter body 100, reducing space occupation and the risk of damage.

[0041] Specifically, the aforementioned acquisition motherboard 230 can perform the functions of acquisition, transmission, and display screen connection. The specific circuit diagram is shown below. Figure 7 As shown, the acquisition motherboard 230 uses the BC28 wireless communication module, which has the advantages of being compact, high-performance, and low-power.
