  • Sulfur hexafluoride (SF6) Frequently Asked Questions

    2013-12-17There are many instruments available that can detect SF6 concentrations in the parts per billion (ppb) range, and some which are reported to be in the parts per trillion (ppt) range. Because you can detect SF6 at very low levels tracer gas applications do not need very much SF6 to be released.

  • DILO Mass Flow Meter: Accurate Measurements of SF6 volume

    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.
