Ultrasonic Gas Flow Meters Energoflow GFE-211 and Energoflow GFE-212 are a brilliant example of genial engineering for achieving an optimal solution for gas flow measurement in large pipes and in cases where installation of inline meters is technically or commercially not viable.The meter comprises of electro-acoustic transducers hot tapped into the existing pipeline and connected to a remote electronics block. Of great importance is the exact positioning of the transducers. This is achieved by our engineers by using special methods and technologies and using a special tool for hot-tapping without the need to stop the flow in the pipeline.

Besides the reduction of cost, especially in the case of large pipelines where the flow meter body constitutes a major part of the cost of the device and installation calls for a capital effort, Energoflow GFE-211 and Energoflow GFE-212 gas flow meters provide all the traditional advantages of pulse-time ultrasonic technology – no pressure loss, no moving parts, reliable and accurate measurement, and easy servicing. They can be installed on pipeline 100 mm up to 1600 mm in size and can be used for a wide range of media like petroleum gas, flue gas coal gas, etc.

The standard version of these flow meters can measure flow velocities in the range of 0.1 m/s …35 m/s. A special version of these flow meters is available for the measurement of flare gas where flow velocity can be as high as 70 m/s.

Some Specific Applications

Volumetric flow measurement of impure gases for technical purposes

Since there are no moving or protruding parts, the GF flow meters can easily handle gases with liquid droplets and suspended particles like soot. Generally flow meters GFE 211, GFE 212 with embedded sensors are recommended for such applications – the sensors can be taken out once in a while for cleaning without stopping the technical process.

Monitoring systems for pipelines, including applications where bidirectional or reverse flow may occur, eg., at pipeline junctions.

In case of complex pipelines with more than one feeder, there are cases of reverse or bidirectional flow due to pressure topography. Monitoring such flow requires highly sensitive flow meters. The GFE 212 series flow meters are capable of recording flow velocities as low as 0.1 m/s which makes them ideal for such applications.

  • Accuracy better than 1%;
  • Pipeline diameter 50 mm upto 400 mm;
  • Range not less than 1:160;
  • Working pressure from 1 to 100

Energoflow AG has recently completed the turn-key installation of a natural gas flow measurement complex comprising of four GFE 212 ultrasonic flow meters – three DN300 and one DN800 for Intergas Central Asia in Kazakhstan.

For measuring gas flow in flares at compressor stations where the flow velocities can be in the range of 0.1 m/s upto 70 m/s.

We can provide specially designed low cost flow meters GFE 201 with very wide range ability (1:160) which can accurately and reliably measure flow velocities from 0.1 m/s upto 70 m/s. The fast reaction of the electronics unit paired with this huge range ability provides the best solution to flare gas measurement.
