Automatic storm water monitoring systems

Automatic storm water monitoring systems t)rpically consist of a rain gauge, flowmeter, automatic sampler, and power source. The rain gauge measures on-site rainfall. The flowmeter measures the runoff water level and converts this level to a flow rate. In many systems, the flowmeter activates the sampler when user-specified conditions of rainfall and water level have been reached. Once activated, the sampler collects water samples by pumping the runoff water into bottles inside the sampler. 

Automatic storm water monitoring systems can form fhe flow-weighted composite sample automatically during the storm event, if there is sufficient storage capacity to accommodate variations in the runoff amount. Such automatic samplers are described in Refs. [8,16,17].
