Dam seepage monitoring system - efficiently obtaining seepage information to assist in the safety management of water conservancy projects.

The seepage monitoring system mainly consists of on-site detection equipment, remote monitoring equipment, and other components.

On site testing equipment: composed of measuring weirs, triangular weirs, etc., responsible for measuring the seepage flow data of the reservoir and monitoring the flow rate on site.

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

Introduction

The water measuring weir adopts magnetostrictive sensors for liquid level measurement, which have the characteristics of high resolution, good stability, reliable performance, fast response speed, linear measurement, no wear, and long working life. The water head on the weir is measured by a measuring weir, and the flow rate is calculated based on empirical formulas for weir channels (triangular weir, trapezoidal weir, rectangular weir, etc.).

Structure and Principle

The water measuring weir is composed of a magnetic rod, a floating ball, a measuring circuit, and a stainless steel casing. When the water level in the weir tank changes, it will drive the floating ball to produce a liquid level difference. The upper computer uses the current liquid level to subtract the calibrated base value to obtain the actual water level on the weir, and then calculates the flow rate based on the type of weir tank.
