Summary

The findings presented here are the continuation of a series of studies begun in 1998 to test water level sensors under a variety of hydraulic conditions.  This report is intended as a supplement to the original 1999 report, entitled "Water Level Sensor and Datalogger Testing and Demonstration" (ITRC Report No. R 99-002), which describes the testing processes in detail and presents detailed results for the first 17 sensors tested.  The 2003 research, summarized in this report, includes the testing of five new sensors.
