Vibrating Wire Weir Monitor

Commonly installed in V-Notch Weirs, the Vibrating Wire Weir Monitor 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 a vibrating wire transducer, this is housed in a cylinder made of slotted PVC pipe. The weight hangs partially submerged in water, as the water level changes the buoyant weight acts on the transducer. This water level change is read in frequency at the instrument, which can be manually read or automated with a datalogger.
