Laboratory Levels of Precision in the Field
Measurement is the first step to control
Featuring dual ultrasound measurement modes in the form of a “continuous wave” which uses a signal of constant frequency and amplitude and the advanced “chirp” signal processing mode in which time varying signals are used, to ensure that the high measurement accuracy is maintained over a wide range of flow velocities.
The TFS ultrasonic transducers may be Fluenta’s most basic offering, but they do not fall short when it comes to performance. Working on the time-of-flight principle, they offer a non-intrusive method of measurement designed to be used in difficult and rapidly changing conditions. Fluenta is able to offer laboratory levels of precision in the field by featuring dual ultrasound measurement modes, one of them being the advanced “chirp” signal processing mode in which time varying signals are used, to ensure that the high measurement accuracy (as high as ±1%) is maintained over a wide range of flow velocities.
Fluenta transducers help the user to future-proof their installation, as although current regulations typically ask for 5% accuracy, with greater control over flaring being the long-term goal, regulations will inevitably tighten. And measurement is the first step to control!
With ultrasonic measurement being less affected by the composition and cleanliness of the gas flow, which enables it to deliver good repeatability regardless of turndown ratio or temperature range, it is the ideal solution for measuring flaring
Onshore and Offshore Installations
Having an operating temperature range of -110 to +145°C makes the TFS transducers suitable for most standard flaring applications, both in onshore and offshore installations.
Features and Highlights
The TFS can be installed in either a single path or a dual path configuration. The dual path can be configured to either provide heightened security in terms of redundancy, when data continuity is of utmost importance or a more accurate measurement as with a dual path accuracy as high as ±0.1% can be achieved.
To achieve accurate readings, the TFS only requires 15 pipe diameters worth of straight piping (10 diameters upstream and 5 diameters downstream)
While the TFS transducer is constructed from SS316/Titanium as a standard, it may be available in other custom materials as well such as Incomel, Hastelloy, Duplex, 6Mo etc.
