Description

Technical Field

[0001] This invention relates to the field of testing equipment, and more specifically to an electromagnetic network flow measurement system. Background Technology

[0002] Currently, open channel flow monitoring mainly relies on technologies such as radar flow meters, ultrasonic time-of-flight flow meters, and individual ultrasonic flow meters. However, existing technologies have significant drawbacks. Radar flow meters rely on reflections from water surface ripples, making them susceptible to wind interference, leading to false alarms in static water or inaccurate dynamic data. Ultrasonic time-of-flight flow meters are complex to install and debug, and the mechanical acoustic waves are easily affected by water impurities, density, and probe impact, resulting in large data deviations. Individual ultrasonic flow meters often require bottom mounting, also facing acoustic interference problems, making it difficult to guarantee accuracy.

[0003] This invention addresses the technical problems of low accuracy, poor anti-interference, and cumbersome deployment in traditional methods by using multi-sensor networking and electromagnetic fluid induction technology, thereby improving flow measurement efficiency and reliability. Summary of the Invention

[0004] The purpose of this invention is to provide an electromagnetic network flow measurement system.

[0005] To achieve the above objectives, the present invention provides the following technical solution: Preferably, an electromagnetic network flow measurement system includes a radar level gauge, an electromagnetic flow meter main unit, connecting cables, and electromagnetic velocity sensors, as well as a pole and a water storage structure. The electromagnetic flow meter main unit is located on the upper part of the pole, and a crossbar is fixed to the upper part of the pole. One end of the crossbar is fixedly connected to the pole, and the other end is fixedly connected to the radar level gauge. The end of the crossbar that holds the radar level gauge is located on the upper part of the water storage structure. Three electromagnetic velocity sensors are installed inside the water storage structure. One end of the connecting cable is electrically connected to the electromagnetic velocity sensors, and the other end is electrically connected to the electromagnetic flow meter main unit.

[0006] Preferably, the radar level gauge is located 2 to 5 meters above the water storage structure and does not directly contact the water.

[0007] Preferably, the electromagnetic flowmeter host is equipped with a host model algorithm.

[0008] Preferably, the electromagnetic flow velocity sensors are respectively installed on one side of the side wall and one at the bottom of the water storage structure.

[0009] Preferably, the flow rate sensor and the water storage structure are connected in a base-type or wall-mounted manner. Beneficial effects

[0010] This invention effectively solves the problems of radar flow meters, which only measure surface velocity and are susceptible to wind interference leading to inaccurate data, and ultrasonic flow meters, which are difficult to install and debug and are easily affected by water impurities and impacts, resulting in invalid data. Using a network of multiple electromagnetic sensors as its core, combined with a radar level gauge and a host computer for rapid calculation, it can accurately collect and output multiple parameters such as channel velocity, water level, and flow rate. Furthermore, the electromagnetic sensors have a fluid-like shape with low resistance, which does not affect the flow measurement accuracy. The system is also highly waterproof and easy to install and disassemble.

[0011] It also boasts advantages such as small size and low cost, providing a high-precision and high-reliability solution for flow measurement in medium and large channels, significantly improving flow measurement efficiency and practicality.

Detailed Implementation

[0014] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0017] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0018] like Figures 1-2 As shown, an electromagnetic network flow measurement system includes a radar level gauge 1, an electromagnetic flow meter main unit 2, a connecting cable 3, and electromagnetic velocity sensors 4. It also includes a pole and a water storage structure. The electromagnetic flow meter main unit 2 is mounted on the upper part of the pole, and a crossbar is fixed to the upper part of the pole. One end of the crossbar is fixedly connected to the pole, and the other end is fixedly connected to the radar level gauge 1. The end of the crossbar that holds the radar level gauge 1 is located on the upper part of the water storage structure. The water level is determined by the distance between the rise and fall of the water level, and the water depth in the channel is measured in real time. Three electromagnetic velocity sensors 4 are installed inside the water storage structure. One end of the connecting cable 3 is electrically connected to the electromagnetic velocity sensors 4, and the other end is electrically connected to the electromagnetic flow meter main unit, for transmitting the data measured by the electromagnetic velocity sensors.

[0019] Preferably, the radar level gauge 1 is located 2 to 5 meters above the water storage structure and does not directly contact the water.

[0020] Preferably, the electromagnetic flowmeter host 2 is equipped with a host model algorithm.

[0021] Preferably, one electromagnetic flow velocity sensor 4 is installed on one side of the side wall and one at the bottom of the water storage structure.

[0022] Preferably, the electromagnetic flow rate sensor 4 is connected to the water storage structure via a base-type connection or a wall-mounted connection.

[0023] Working principle First, three electromagnetic flow velocity sensors 4 are placed inside the water storage structure to monitor the water flow velocity using the principle of electromagnetic field fluid induction. At the same time, a radar level gauge 1 is installed on the crossbar at the top of the water storage structure to monitor the water depth in the channel in real time. The electromagnetic flow meter host 2 collects water flow velocity data from the electromagnetic flow velocity sensors 4 and water depth data from the radar level gauge 1 every 10 seconds at the fastest. After receiving the data, the electromagnetic flow meter host 2 calls the internally preset calculation model to calculate parameters such as flow velocity, flow rate, and water level at the channel cross-section. Finally, the calculated flow measurement data is displayed on the screen, completing one flow measurement cycle. This process is then repeated to achieve continuous flow measurement.

[0024] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0025] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
