  • (1) - Length without unions.

  • (2) - PN 16 flanged connections.

  • Qn - Nominal flow: Maximum continuous flow measurable by the meter.

  • Qmax - Maximum temporary flow bearable by the meter.

  • Qt - Transition flow: minimum limit with error less than ±3 %.

  • Qmin - Minimum flow limit: minimum limit with error less than ±5 %.

  • Kvs - Flow coefficient: Flow in m³/h with pressure drop of 100 kPa = 10 mWG = 1 bar.

  • ∆p Qn - Pressure drop at nominal flow Qn.
