  • Custody transfer measurement of LNG

  • On- and offshore applications

  • Liquefaction, transport and storage of LNG

Device properties:

  • Intrinsically safe and reliable ultrasonic transducers

  • Conform to OIML R117 Cl. 0.3 and API MPMS Ch. 5.8

  • Real time measurement and diagnostics

  • Full bore design without pressure drop or need for flow conditioner

  • Factory thermal pre-insulation

  • Remote Signal Processing Unit

Benefits

  • Low measurement uncertainty directly at custody transfer point reducing financial risks during LNG-transaction

  • Increased transparency during LNG transaction by dynamic & real-time measurement &
    diagnostics

  • Operational expenditure savings by reduced boil-off gas losses and efficient LNG transfer due to minimized pressure drop

  • Capital expenditure savings by simpliefied meter integration and installation due to compact design and factory pre-insulation

  • Easy and fast access during commissioning and regular checks with remote SPU
