Steam/water interfaces in the various high pressure and high temperature steam drums operated inelectricity-generating power plants, glass, cement, petro-chemical, steel, and paper making plants requireclose monitoring and controlling for safe, efficient and reliable operation. Since most of these steamdrums normally operate at very high pressure and temperatures, any malfunction of  the level measuringand controlling instruments must be prevented so that serious interruptions and costly damages to theprocess or equipment can be precluded. 

In spite of the importance of close monitoring and controlling of the drum levels, industries in the pasthave relied on such devices as glass and float-type level switches. But they often malfunctioned, andrequired service or replacement interrupting the normal operation and processes. Based on many years ofexperience as the leading supplier of level and flow sensing instruments and in-company technologicalinnovation, Seojin Instech has succeeded in developing this electrode-type steam drum interfacemonitoring system that operates reliably in the extremely high pressure and temperature environment ofup to 300 kg/cm² and 560°C .
