Flow measurement of natural gas
Measurement of the standard volume flow (with DGM functionality) of natural gas on a compressor station
Measuring and calculation of gas standard volume flow at compressor station
Gas transport means transmission from the production sites to the consumption area to feed gas into the distribution networks there. The gas transport network can be compared to a motorway as it is made up of large axes, while the distribution networks are made up of shorter axes that route the gas directly to the consumer. At a national level, long-distance pipelines of the gas transport network efficiently connect the storage caverns or aquifers with the distribution networks. A key requirement for the smooth functioning of the infrastructure is information about the gas volumes that flow from one region to another or from one company to another.
The non-intrusive ultrasonic measuring system measures accurately standard volume flow incorporating Dynamic Gas Meter (DGM) functionality for direct compressibility factor, density and molar weight calculation, bypassing the need for extensive additional instrumentation.

Product Solutions
The Flexim FLUXUS G722 gas flow meter is a high performing ultrasonic clamp-on meter specifically designed for measurement of dynamic flows in the process industry. This sophisticated, versatile, and accurate flow meter has everything you need - faster processing capabilities, advanced diagnostics, bidirectional communication protocols, digital outputs, and process inputs. The G722 offers ease of installation, retrofittable design, accuracy, and outstanding performance. Using the new Synchronized Channel Averaging method (SCA), the G722 ultrasonic flow meter sends signals both in the direction of the flow and against the flow every 1millisecond.
- Accuracy and repeatability - exceptional reliability and accuracy at high and low flows due to matched, calibrated and temperature compensated transducers, advanced signal processing capabilities and diagnostics.
- Easy installation without process interruptions - an externally mounted system means no need for process interruptions or additional engineering costs.
- Maintenance-free - no contact with flowing media results in a completely maintenance-free and durable metering solution to withstand even the harshest environments.
