The SIPP Node has an integrated sensor for real-time monitoring of the current water level in the catch basin of your transformer station. When the water level you have pre-defined is reached, the discharge begins. The SIPP Node directs the water from the catchment basin to its measuring cell, which detects the oil content in the water. The filter upstream of the measuring cell (filtration degree 10 μm) removes solids and impurities from the water and thus prevents the results from being affected. With a measuring accuracy of +/- 1 ppm, the measuring cell uses infrared light to determine the oil content in the water every second. Subsequently, the control module regulates the discharge or, if necessary, the return of the water into the catch basin. The SIPP Node discharges only unpolluted water into the environment, which does not exceed the maximum permissible oil content (e.g. max. 5 ppm for transformer stations and discharge into the sewer system).
