Description
Technical Field
[0001] This utility model relates to the technical field of ultrasonic flow meter production equipment, specifically to a rapid pairing device for ultrasonic flow meter sensors. Background Technology
[0002] Ultrasonic flow meters are widely used flow measurement devices in industrial, municipal, and environmental protection fields. They measure flow velocity and flow rate by measuring the propagation time of ultrasonic waves in a fluid. The core components of an ultrasonic flow meter include the flow meter unit and the sensor. The sensor is typically mounted on the pipe to transmit and receive ultrasonic signals, while the flow meter unit is responsible for signal processing and data calculation. In practical applications, the ultrasonic flow meter's sensor and unit require precise pairing and calibration to ensure measurement accuracy and stability.
[0003] Traditional ultrasonic flow meter sensor pairing processes typically rely on manual operation. Operators need to manually connect the sensor to the main unit and perform signal detection and calibration using debugging equipment. This manual pairing method has the following problems: 1. Low efficiency: The manual connection and debugging process is time-consuming, especially when multiple sensors and the main unit need to be paired simultaneously, significantly reducing operational efficiency; 2. Difficulty in guaranteeing accuracy: Manual operation is prone to introducing errors, especially during the connection and fixing of sensor signal lines, which may lead to unstable signal transmission and affect measurement accuracy; 3. Complex operation: Traditional pairing devices have a simple structure and lack precise positioning and fixing functions for the sensor and the main unit. Operators need to repeatedly adjust the position of the sensor and the main unit, increasing the complexity of the operation; 4. Poor compatibility: Different specifications of sensors may require different pairing devices, and traditional devices are difficult to adapt to the rapid switching and pairing needs of multiple sensor specifications.
[0004] To address the aforementioned issues, existing technologies have proposed several improvements, such as employing automated pairing devices or adding positioning structures to enhance pairing efficiency. However, these solutions still have limitations. For instance, automated devices are costly and difficult to adapt to complex field environments; while simple positioning structures cannot meet the compatibility requirements of multiple sensor specifications.
[0005] Therefore, there is an urgent need for a device that can quickly, accurately, and efficiently pair ultrasonic flow meter sensors with the host unit to improve pairing efficiency, ensure measurement accuracy, and adapt to the needs of various sensor specifications. Summary of the Invention
