High precision ultrasonic flow meter for liquid and LNG

Applications

  • Custody and process measurement of petroleum and petroleum oil products
  • Custody and process measurement of liquefied natural gas (LNG)
  • Liquid measurement and control for gas reforming process
  • Liquid measurement for petroleum oil processing companies
  • Liquid measurement for food processing companies
  • Liquid measurement for chemical production plants
  • Custody and process heat energy measurement

Your benefit

  • Measurement flow rate error limit 0.3%
  • Wide flow rate range from 0.03 m/s to 25 m/s
  • Operating pressure up to 50 MPa
  • Operating temperature range from -200 °С to + 300 °С
  • Viscosity limit of the fliud up to 1000 cSt
  • Mass flow measurement
  • Measurement of chemicals
  • Weld free meter body is designed for extreme operation pressures from 10 MPa to 50 MPa
  • High-tech titanium and stainless steel ultrasonic transducers ensure stable signal even in harsh process conditions
  • High level of measured ultrasonic signal allows to use transducers on pipe diameters up to 3000 mm
  • Self-diagnostics while working with status recording in the archive
  • Applicable in heat energy measurement systems without external solvers
  • Up to two pressure sensors and up to two temperature sensors can be connected
  • Can operate air temperatures down to -60 °C using external heating cover
  • Less need for metrological verification: once every 4 years
  • Lifetime of the device is not less than 15 years
