Description

Technical Field

[0001] This utility model relates to the field of flow measurement equipment technology, specifically a multi-interface platform electromagnetic flow meter. Background Technology

[0002] An electromagnetic flowmeter is a flow measurement instrument that works based on Faraday's law of electromagnetic induction. Its core function is to measure the volumetric flow rate of conductive liquids (such as tap water, sewage, acid and alkali solutions, excluding non-conductive media such as oil and gas). It features high measurement accuracy, no moving mechanical parts, and strong anti-interference ability.

[0003] Traditional electromagnetic flowmeters are mostly designed for single flow measurement. If parameters such as temperature and pressure need to be monitored, separate sensors must be installed, resulting in multiple pipe openings, complex installation, and limited expansion. External sensors, on the other hand, need to indirectly contact the liquid being measured through pressure taps or flow guides. This introduces risks such as measurement delays (e.g., temperature sensor response time exceeding 10 seconds) and flow channel contamination. Regular cleaning of the external module is also required. Furthermore, incompatibility between different brands affects their versatility and causes numerous inconveniences.

[0004] Based on the above reasons, this utility model designs a multi-interface platform electromagnetic flowmeter, which can directly connect to the liquid being measured through an open external interface, supports the rapid embedding of various third-party sensors, and thus realizes real-time synchronous measurement of multiple parameters. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a multi-interface platform electromagnetic flowmeter that can directly connect to the liquid being measured through an open external interface, supports the rapid embedding of various third-party sensors, and thus realizes real-time synchronous measurement of multiple parameters.

[0006] To achieve the above objectives, this utility model provides a multi-interface platform electromagnetic flowmeter, including a main body. External interfaces are distributed on the outer wall of the measuring tube at the lower part of the main body. The external interfaces are evenly distributed along the axial direction of the measuring tube. The interior of the external interface is directly connected to the inner cavity of the measuring tube. The external interface is separated from the main magnetic field area of ​​the main body by a certain distance. An elastic sealing element is provided inside the external interface, and a plug is provided at the top of the external interface.

[0007] The external interface has threads on the outside for connecting to external sensors.

[0008] The external interfaces include External Interface 1, External Interface 2, External Interface 3, External Interface 4 and External Interface 5. The model of External Interface 1 is M12×1.5, the models of External Interface 2 and External Interface 5 are M16×1.5, and the models of External Interface 3 and External Interface 4 are M20×1.5.

[0009] The included angle between adjacent external interfaces is 60 degrees.

[0010] The seals are made of polytetrafluoroethylene or O-rings.

[0011] Compared with existing technologies, this invention, by setting external interfaces at equal intervals on the outer wall of the measuring tube of the electromagnetic flowmeter sensor body, which directly communicate with the inner cavity of the measuring tube, allows for the direct connection of various sensors to the external interfaces. This achieves platform expansion with multiple interfaces while ensuring the synchronization of measurement data and reducing latency. Furthermore, the inclusion of elastic seals and plug designs ensures high liquid tightness, enabling the same device to meet the needs of multiple industries and multi-parameter measurements, such as chemical, water, and food, simply by replacing different external sensors.

[0016] The present invention will now be further described with reference to the accompanying drawings.

[0017] See Figures 1-2 This utility model provides a multi-interface platform electromagnetic flowmeter, including a body 1. External interfaces are distributed on the outer wall of the measuring tube 2 at the lower part of the body 1. The external interfaces are evenly distributed along the axial direction of the measuring tube. The interior of the external interface is directly connected to the inner cavity of the measuring tube 2. The external interface is separated from the main magnetic field area 10 of the body 1 by a certain distance. An elastic sealing element 9 is provided inside the external interface. A plug 8 is provided on the top of the external interface.

[0018] The external interface has threads on the outside for connecting to external sensors.

[0019] The external interfaces include external interface 1 (3), external interface 2 (4), external interface 3 (5), external interface 4 (6), and external interface 5 (7). External interface 1 (3) is model M12×1.5, external interface 2 (4) and external interface 5 (7) are model M16×1.5, and external interface 3 (5) and external interface 4 (6) are model M20×1.5.

[0020] The included angle between adjacent external interfaces is 60 degrees.

[0021] Seal 9 is made of polytetrafluoroethylene or an O-ring.

[0022] Working principle:

[0023] See Figures 1-2 This invention requires minimal debugging. Five external interfaces are evenly distributed along the axis of the measuring tube 2, with an angle of 60 degrees between adjacent interfaces. This ensures sufficient space for most external sensors. Installation is completed simply by connecting the external sensor to the threaded portion of the external interface. The external interfaces have three different thread types, accommodating a wide range of sensor types and models on the market for better compatibility. The external connectors are positioned outside the main magnetic field region 10 of the electromagnetic flowmeter body 1. This ensures that the external sensor installation does not affect the magnetic field distribution of the main sensor, avoiding interference that could impact sensing accuracy and efficiency. Since the inward openings of each external interface correspond to the openings at the corresponding positions on the measuring tube 2 and are directly connected to the cavity of the measuring tube 2, relevant data parameters of the internal liquid can be directly obtained. Measurements show that because the external interfaces are directly and in real-time connected to the measured liquid, the external sensors and the main flow sensor share the same flow field, resulting in a measurement delay of less than 1 second. Multiple external connectors can measure multiple parameters simultaneously without interference, which avoids the shortcomings of existing technologies that require additional pressure taps or guide tubes, such as delays and accuracy losses. It also achieves the requirement of efficient operation. In addition, the seals prevent liquid leakage, and the plug design makes sealing more convenient.

[0024] The above are merely preferred embodiments of this utility model, intended only to aid in understanding the method and core concept of this application. The scope of protection of this utility model is not limited to the above embodiments; all technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the scope of protection of this utility model.

[0025] This invention addresses the shortcomings of existing electromagnetic flowmeters, which are mostly limited to single flow measurement and cannot be further expanded, as well as the measurement delay caused by the need for external sensors to indirectly contact the measured liquid through pressure taps or flow guides. By directly setting an external interface on the measuring tube of the electromagnetic flowmeter, various external sensors can be directly connected to the DC channel inside the cavity to directly measure various parameters of the internal liquid, greatly reducing the data acquisition delay. Multiple external interfaces can adapt to the multi-parameter measurement needs of multiple fields, while also ensuring sealing. Overall, it achieves fast, efficient, stable, low-latency, and low-cost real-time parameter measurement.
