  • Patent number: 10738789
    Abstract: A turbomachine has a casing where liquid may accumulate; at least one liquid level detector is located inside the casing for automatically detecting liquid accumulated inside the casing during operation of the turbomachine; the liquid level detector may be arranged for detecting one or two or three or four liquid levels inside the casing; the liquid level detector is typically connected to an electronic unit at least for automatically signaling the liquid level. The electronic unit controls at least one valve for automatically discharging the accumulated liquid from the casing; in this way, the status of the turbomachine is not only monitored but also managed.
