The GWR-101 provides sophisticated monitoring and logging of essential Ground Water Level conditions. This instruction manual takes you step-by-step through the process of assembling, testing, and installing your Ground Water Level Recorder so you can begin collecting data as soon as possible The purpose of this manual is to provide basic operating knowledge of the components of the automated recorder used for periodic water level measurement.

Much more than just a supplement to the broader water level program, these automated recorders provide a means to India that cannot be discerned from annual level readings. The design of document day-to-day changes and seasonal patterns in the aquifers of these units also allows for remote satellite transmission of collected data, so that aside from installation and occasional maintenance, no additional work is required to obtain these measurements. This manual will primarily discuss the 3 major technical components of the automated recorder— the sensors, loggers & transmitters— for automated water level monitoring.
