Gas flowmeters Turbo Flow UFG-F

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. 

Based on temperature range of ambient environment and medium measured:

• configuration М - from minus 30 to plus 70;

• configuration Х - from minus 50 to plus 70.

Based on components and performed functions:

• Configuration С0 – includes an ultrasonic flow transducer, an electronic unit;
• Configuration С1Т - includes an ultrasonic flow transducer, electronic unit, temperature transducer, flow computer integrated in electronic unit;

• Configuration С1ТР - includes an ultrasonic flow transducer, electronic unit, temperature transducer, flow computer integrated in electronic unit, pressure transducer;

• Configuration  С2ТР - includes an ultrasonic flow transducer, electronic unit, temperature transducer, a flow computer remotely installed in a flow-measurement cabinet, pressure transducer;

• Configuration С3ТР - includes an ultrasonic flow transducer, electronic unit, temperature transducer, pressure transducer, a Raskhod-1 flow computer.

• Configuration С4 - includes an ultrasonic flow transducer, electronic unit, temperature transducer, pressure transducer, a Superflow-23 gas volume corrector.

Based on explosion protection:

• 1 Ex dib [ia Ga] IIC T4 Gb;
• 1 Ex d [ia Ga] IIC T4 Gb.

Based on redundant computer aids:

• One computing unit;

• Two computing units;

• Two computing units, redundant flow parameter measuring equipment ("two-in-one" configuration).

A special-purpose removable attachment allows performing the on-site "hot" swapping of ultrasonic sensors without pressurizing the main pipeline and without dismantling the flowmeter.
