Weir Monitor (VW)

Weir Monitor (VW)



The Model 4675LV is a water level monitoring system that uses a vibrating wire force transducer to provide a highly stable and sensitive means of monitoring water levels. The main component is a cylindrical weight suspended from the force transducer. The cylinder hangs partially submerged in the water whose level is to be monitored. As the water level changes, the changing buoyancy force on the cylinder acts directly on the vibrating wire transducer and alters its tension, and hence its resonant frequency.
