Weir or V-Notch is a simple system by which the leakage volume of a dam is measured.  This device is an important part of a monitoring system at dams, which is manufactured in different sizes and forms.  The device is composed of a non ferrous metal (Aluminum or stainless steel) which is manufactured and calibrated so that the hight of the passing water is associated with a volume of water.

We manufacture these heavy pieces in our factory and calibrate them with accurate pumps.
