Abstract There is provided a water pollution monitoring system which may be coupled with data handling and processing equipment while the water pollution monitoring system is functioning. Varying levels of pollutents are detented by means of a variety of sensors and an electrical signal corresponding to the pollutant level is processed for recording and/or transmission. Means are provided for automatic periodic cleaning of the sensors so that a high level of accuracy can be maintained for an extended period of time. Additional means are provided for data reduction within the system to reduce massive volumes of detected information to that which is specifically of interest to the equipment operator. Still further means are provided for controlled suspension of the system in aqueous media to maximize system operation.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
91 words
A fluid analyzing apparatus for in situ analysis of fluids comprising: a container which is open at one end, a plurality of sensors fixedly mounted within said container for sensing characteristics of said fluid and producing electrical signals, data recording means for receiving said electrical signals from said sensors, means within said container for periodically inducing oscillatory displacement of said fluid thereby cleaning said sensors, means for selective excitation of said means for inducing oscillatory displacement, and means for sequentially switching individual ones of said sensors and said data recording means.
