V-Notch Weirs and Tanks

V-Notch Weirs and Tanks from are precision-engineered systems designed for accurate open-channel flow measurement in hydrology, environmental monitoring, mining operations, and geotechnical projects. Built on internationally recognized hydraulic principles, these systems provide consistent and reliable flow calculations for low-flow conditions, making them ideal for performance monitoring, environmental compliance, and long-term water management programs.

Because water flow in many field environments varies significantly over time, a stable and repeatable measurement structure is essential. V-Notch Weirs and Tanks ensure this stability through robust construction, high-quality materials, and calibrated geometries that maintain accuracy even in harsh field conditions. Moreover, they are designed to integrate seamlessly with water level sensors, such as vibrating-wire piezometers or automated dataloggers, enabling real-time monitoring and historical trend analysis.

In addition, the V-notch design provides superior sensitivity to low discharge levels, allowing engineers to detect subtle variations in flow that would otherwise be missed by other measurement structures. This makes them especially useful for groundwater discharge studies, seepage evaluation, dam safety programs, and environmental impact assessments. With straightforward installation and minimal maintenance requirements, V-Notch Weirs and Tanks offer a practical yet highly precise solution for long-term hydrometric monitoring needs.
