Description

Technical Field

[0001] This application belongs to the field of hydrological measurement instrument technology, and in particular relates to an intelligent remote measurement and control integrated weir meter. Background Technology

[0002] Magnetostrictive weir gauges are suitable for long-term measurement of water levels in rivers, lakes, reservoirs, dams, and other weir channels. They are effective monitoring devices for monitoring water level and flow changes. Using a magnetostrictive level gauge as the sensor, the weir gauge offers advantages such as high resolution, high precision, high stability, high reliability, fast response, and long service life. The main functions of the magnetostrictive weir gauge include linear measurement, absolute position output, non-contact continuous measurement, and wear-free operation. It requires no recalibration or periodic maintenance and offers multiple output signal options. Traditional water level monitoring equipment generally suffers from the following problems: insufficient accuracy: mechanical float level gauges are easily affected by contaminants, leading to large measurement errors; high maintenance costs: periodic calibration or component replacement is required, making it difficult to adapt to unattended environments; isolated data: most devices lack real-time data transmission capabilities, preventing remote monitoring; and limited functionality: relying on a single sensor and lacking multi-dimensional data verification capabilities.

[0003] Although magnetostrictive level gauges have advantages such as high precision and non-contact measurement, they still face challenges in water conservancy applications, including waterproofing, long-term power supply, and data fusion. Summary of the Invention
