Model 4675LV Weir = Monitor
The Model 4675LV water level monitoring system = uses a=20 vibrating wire force transducer to provide a highly stable and = sensitive=20 means of monitoring water levels. The main component is a = cylindrical=20 weight suspended from the force transducer. The cylinder hangs = partially=20 submerged in the water whose level is to be monitored. As the = water level=20 changes the changing buoyancy force on the cylinder acts directly = on the=20 vibrating wire transducer and alters its tension and hence its = resonant=20 frequency. The frequency is measured either by the GK-403 portable = readout, the MICRO-10 Datalogger or the Model 8001 Single Channel=20 Datalogger.
