FLOWSIC100 Flare-XT

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.
