Mass Flow Meter For recording gas quantities from and to the circuit breaker. B152R41/51. SF 6 Mass Flow Meter. The SF 6 Mass Flow Meter can be used to accurately measure the quantity of SF 6 (in lbs/mass) as it is either filling equipment, or during gas recovery. Because the measurement is based on the volume of gas passing through the device, traditional cylinder weighing is not required.

    SF6 gas leakage - SF6 breakers (live and dead tank) typically have a combination of static seals (O-rings and gaskets) as well as dynamic seal assemblies where the mechanism energy is transferred through to the interrupter assembly. Over time, seals degrade due to environmental conditions and exposure and will need to be replaced.
