The seepage monitoring system is mainly composed of field monitoring equipment, remote monitoring equipment and other parts.

On-site detection equipment: consisting of measuring weirs, triangular weirs, etc., responsible for measuring the amount of seepage from the reservoir and monitoring the flow rate at the reservoir site.

Remote monitoring equipment: namely, remote control monitoring terminal, is responsible for collecting the data information detected by the on-site monitoring equipment, and transmitting the on-site information to the monitoring center through wireless transmission.

Introduction

The measuring weir adopts a magnetic expansion sensor for liquid level measurement, which has the characteristics of high resolution, good stability, reliable performance, fast response speed, linear measurement, no wear, and long working life. The measuring weir measures the water head on the weir, and then the flow is calculated according to the empirical formula of the weir slot (triangle weir, trapezoidal weir, rectangular weir, etc.).

Structure and principle

The flow meter consists of a magnetic rod, a floating ball, a measuring circuit, and a stainless steel protective tube. When the water level in the weir changes, it drives the floating ball to produce a liquid level difference. The host computer calculates the actual water level on the weir by subtracting the calibrated baseline value from the current liquid level, and then calculates the flow rate according to the type of the weir.
