  • INNOVA 3731 - SF6 leak detection system for enclosed

    2019-8-1leak detection solution capable of monitoring large switchgear rooms. The system verifies that the GIS Equipment operates below the industrial target of 0.5% yearly leakage rate or better. The 3731 system can detect—with a short response time—any excessive increase in the leak rate, enabling to decrease the number of periodic leak checks while

  • Fundamentals of leak detection - Leybold

    2017-1-12The leak rate of a vessel indicates the amount of gas flow which escapes through the walls of the vessel. It must be noted, however, that the leak rate for a leak depends on the type of gas. If the gas temperature T and the molar mass M of a gas G is known, the gas mass flow can be calculated from the leak rate
