V-Notch Weir (Mechanical)

V-Notch weir are meant for the measurement of changes in water level behind a V-Notch weir drainage/leakage monitoring system. The main componets are a  calibrated V-Notch weir, made of stainless steel with proper marking eith 90 or 30 degrees, Cylindrical weight suspended from a vibrating wire force transducer. As the water level changes, the changing buoyancy forceon the cylinder acts directly on the vibrating wire force transducer. This system is callibrated in the engineering units.
