The model ESM-10 V-notch weir is an integral part of the seepage monitoring system. It is designed to measure seepage of water through, around, or under a dam in earth as well as concrete. It is one of the oldest, simplest, and most reliable devices used to measure the quantity of flow of water.
The weir is available in different sizes and angles, depending on application (rate of flow) and project requirement. It is made of high-quality stainless steel material.

Readings from the weir can be taken manually using a staff gauge or stainless steel scale, which is fixed to the side wall (for reading the head above the vortex of the notch). The readings can also be taken in near real time/online with the model ESM-12S/1 digital seepage monitoring sensor and model ESDL-30 datalogger.
