Gas flowmeters Turbo Flow UFG-F

Our dealers

 

Purpose:

Ultrasonic gas flowmeters are intended for high-accuracy measurement (0.3%):

  • Volumetric gas flow rate;

  • Mass gas flow rate

in operating and standard conditions in pipelines DN 50...500 mm.

The electronic computing unit:

  • Takes measurement of gas flow parameters: temperature, pressure.

  • Makes computation of accumulated gas volume.

  • Archives measured parameters.

  • Optional: data transfer via mobile communication or Ethernet links.

For Class A meters - backing up of computer aids (Corporate Standard of Gazprom OJSC).

Field of application:

The Turbo Flow UFG-F gas flowmeters are used for commercial and technological metering of natural, oil and other kinds of gas at production facilities of various industries.

Advantages of method:

  • High accuracy of measurements: measurement error up to 0.3%;

  • Wide dynamic range: 1:200;

  • Flow measurement in both directions;

  • No pressure losses due to full bore diamete. 

 
 Our engineers together with the researchers from the South Federal University carried out a series of studies in the ultrasonic flow measurement field. The twoyear effort has resulted in a unique measuring system based on the special-purpose piezoelectric transducers that are not sensitive to contaminating deposits up to 1 mm thick. This offers the possibility to successfully use our flowmeters for metering
so-called "dirty gas".
