Advantages

Ready for the future: ultrasonic gas flow measurement for flare gas systems

The FLOWSIC100 Flare-XT is characterized by a unique flow-optimized sensor design that provides reliable gas flow measurement and monitoring at extremely high speeds and changing gas compositions. The rugged design guarantees uninterrupted availability of measurements even under adverse conditions. The FLOWSIC100 Flare-XT takes into account a wide range of applicable standards worldwide and is suitable for use in new and existing plants. The measurement and diagnostic data can be easily visualized with the FLOWgateTM software. Thanks to the intelligent i-diagnosticsTM function, the system is able to monitor itself and independently report the need for maintenance. For upstream requirements, e.g. in fracking applications, the FLOWSIC100 Flare-XT transmitter is the right choice as it is rugged and reliable without recalibration.


Flow Measurement with Ultrasonic transit time difference measurement:

Thanks to high-resolution sensors, the state-of-the art electronics precisely detects even very small transit time differences.

Flow Measurement with Ultrasonic transit time difference measurement:

The innovative, flow optimized sensor contour allows optimal measurement results even at very high gas velocities.

Flow Measurement with ASC-technology:

If the signal is blown away due to extreme gas velocity, the patented ASC-technology algorithm ensures uninterrupted measurement.

Accurate flare gas measurement in onshore and offshore facilities in the oil and gas, chemicals, petrochemicals, and refinery industries

Highly accurate data under extreme conditions such as gas velocities of 0 to 120 m/s (340 ft/s), rapid changes in the gas velocity and complex gas compositions.
Thanks to its innovative ASC-technology, FLOWSIC100 Flare-XT is now extending previous maximum flow range by up to 30%.

Upstream or downstream: precise flare gas measurement enables exact monitoring of flare gas emissions

Powerful. Reliable. Robust.

FLOWSIC100 Flare-XT is available in three different types. The variants are available as a single or dual path measurement system. Regardless of the path configuration, the system is available in both the cross-duct version and the probe version with single nozzles. The probe version is suitable for compact, one-sided fitting with minimal installation effort. The dual path type achieves high measurement accuracy even under difficult flow conditions.

Thanks to the device changing unit, fast and simple sensor changes are possible during ongoing system operation. The powerful interface unit can be easily connected to a wide variety of control systems and networks thanks to its numerous interfaces.

The interface unit processes incoming signals and calculates parameters, such as the molecular weight, mass flow and gas volume, as well as standardized reference values.

Upstream and downstream: ready for any situation thanks to leading ultrasonic technology

Sensors made of titanium and optimized for flare flow: The flow-optimized sensor design minimized turbulences and signal dispersion.
Thanks to interference-free, digital communication, the interface unit can be installed up to 1,000 m away from the measuring point. There is therefore no longer any need for a local, pressure encapsulated and potentially expensive control unit.

The sensor signal can be amplified automatically and provides reliable results even if the sensors are contaminated. This is an advantage over other measurement principles, such as thermal mass measurement.

The powerful ultrasonic technology delivers reliable measurement also under extreme conditions during flaring.

Intelligent device monitoring and predictive maintenance

i-diagnosticsTM intelligently links software and firmware: The self-monitoring system delivers valuable data regarding the device status and highlights all changes. Application faults are immediately detected and documented, thereby time-consuming troubleshooting can be omitted. On request, the system verifies itself and records its current status. In this way, users have a very straightforward means of creating documents that prove that all emission regulations are fulfilled.

Simple maintenance. One-click verification. Self-diagnostics.

Predictive maintenance

Flexible service intervals The system continuously monitors performance parameters and generates reliable forecasts and maintenance recommendations based on this data.

1-click verification report

A report can be generated with one click for complete functional verification. This makes it easy to ensure and document compliance with legal requirements.

Self-diagnosis

The intuitive FLOWgate software makes measurement, diagnostic and device data easier to handle, thereby permitting quick and uncomplicated system analysis.

The automatic verification of the measurement system and failure diagnostic reduces the number of service intervals and by that reduces maintenance costs.
