An Electronic Transducer for Continuous Water Level Monitoring

ABSTRACT THE trend of recent hydrologic research has been to increase the detail of physical observations while reducing the spatial extent of the system being studied. This increase in the volume of data, together with the corresponding decrease in the separation between data sources, has encouraged the use of centrally located data acquisition systems. The lack of suitable sensing devices, however, has severaly limited the application of modern data logging techniques to field research in hydrology. This is particularly true where multiple water level measurements are necessary.
