Overview
Precise and robust gas flow meter for flare gas or flare stack applications: Our ultrasonic gas flow measuring instrument FLOWSIC100 Flare-XT is designed for flare gas measurement or flare metering. The high-resolution measurement and innovative sensor design is being developed for most efficient uses in petroleum refineries, natural gas processing or offshore and onshore oil and gas plants. Emission control or monitoring, detection of flare gas leaks, steam flow measurement, monitoring of gas losses, monitoring of steam injection in flare gas burning, as well as process optimization and condition monitoring are fields of use for this gas flow meter. The gas flow meter is measuring values such as gas velocity, gas volume and mass, mass flow rate, molecular weight, volumetric flow a. c., volumetric flow s. c. and sound velocity. The flare gas flow meter provides an intelligent device monitoring process and supports predictive maintenance - designed for current and future challenges.
- Reliable measurement even at high gas velocities and with changing gas compositions
- Proprietary measuring range extension for high flow velocities thanks to ASC technology
- Direct mass flow calculation without additional gas analyzers
- Intuitive FLOWgateTM software for commissioning, operation and diagnostics
- I-diagnosticsTM: self monitoring, self testing and predictive maintenance
- Customized measurement performance thanks to individual evaluation of the application
Advantages

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

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


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.

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
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.
