Features
- Certified for operation within hazardous areas (ATEX/IECEx Zone 2 and FMc Class I, Division 2 certified).
- High sampling rates (output of measurement data every 10 ms), capturing pulsating flows.
- Reliable measurements of slurries or liquids with gaseous entrainments.
- High operational safety with no risk of leaks.
- Independent of pipe material, diameter, wall thickness and internal pressure and temperature.
- Accurate and repeatable measurement readings - even at extremely low flow rates (high turndown ratio).
- Highly cost-efficient in comparison to wetted instrumentation.
- Every measurement system is pre-calibrated in-house (traceable to national standards) and delivered with a calibration certificate.
- Matched transducers, integrated temperature compensation (according to ANSI/ASME MFC-5.1-2011 regulations) and advanced digital signal processing guarantee a high zero-point stability, drift-free and accurate measurement readings.
- Permanent coupling ensures long-term reliable non-intrusive flow measurement even under harsh environmental conditions, such as submersion.
- Bi-directional communication as well as remote parameterization and diagnostic capabilities.
