ABSTRACT
Water quality monitoring systems provide the means of measuring the condition of the water. These systems range from single-parameter measurements to complex systems integrating multiple sensors with data manipulation and recording capabilities, and, in many cases, means for remote communications and data transfer. The design of a water quality monitoring system may consist of a sampling sensor and a data transmission/logging section. A water quality analyzer may be as simple as a probe inserted into the water and connected to a conveniently located recorder—or as complex as a data collection system with multiple sensors distributed in several locations with centralized data recording and compiling. When the purpose of an installation is the monitoring of the water quality of lakes and rivers, the monitoring package must be so designed that it will operate unattended for 30 to 60 days at a time. The submersible assembly is anchored directly in stream and is ideal for monitoring water quality parameters in protected areas.
