Gas flowmeters Turbo Flow UFG-F compact version (up to 1.6MPa)

Purpose:

Ultrasonic gas flowmeters are intended for high-accuracy measurement (1%):

• Volumetric gas flow rate;

• Mass gas flow rate

in operating and standard conditions in pipelines DN 50...100 mm PN16.

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.

Field of application :

• The unit of gas metering stations in gas distribution networks with pressure up to 1.6 MPa.
• Modernization and re-equipment of metering units with measurement systems based on the turbine and rotary meters with electronic correctors.
• Gas metering device nodes in the absence of power.

Specific features of flowmeter:

• Specially selected distance between the flanges of the frame size of turbine and rotary meters;
• Accuracy of measurements 1%;
• Autonomous operation of the device at least 5 years;
• Wide measurement range 1:200;
• No pressure losses;
• No sensitivity to vibration and acoustic noise;
• Intelligent self-diagnostics system;
• Reliability due to absence of moving parts;
• Double-beam system without using the reflection of the beam.

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 S1TR includes an ultrasonic flow transducer, electronic unit, temperature transducer, flow computer integrated in electronic unit, pressure transducer;

• Configuration S2TR includes an ultrasonic flow transducer, electronic unit, temperature transducer, a flow computer remotely installed in a flow-measurement cabinet, pressure transducer;

Based on explosion protection:

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

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.
