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
