The FLEXIM transit-time difference method exploits the fact that the transmission speed of an ultrasonic signal depends on the flow velocity of the carrier medium.
An ultrasonic signal moves slower against the flow direction of the medium than when with the flow direction. For the measurement, ultrasonic pulses are sent through the medium in both directions. The transit-time difference is measured and allows an accurate determination of the volume flow.
The FLUXUS® range of ultrasonic clamp-on flow meters are the most advanced in the world.
They are available with a range of certification options from ATEX zones 1 and 2, FM Class I Div II, IECEx, IP66/67/68 and are capable of withstanding pipe temperatures in excess of 400°C. FLEXIM´s Oil & Gas Division provides a comprehensive service and full support over the full product range wherever it is located.
FLEXIM ultrasonic flow meters
come with a host of unique features:
All FLEXIM flow meters are compliant to ANSI/ASME MFC-5M-1985 (R2001) requirements by temperature compensating the transducers to prevent drift
Every set of transducers leaving the manufacturing facility is calibrated, ensuring both accuracy and zero stability
The digital signal processor calculates up to 1000 flow measurements per second, providing the basis for continual precision measurement
The FLUXUS® clamp-on flow meters are the only systems in the world to use two different transducer technologies to cover the widest range of applications
Solid transducer coupling makes these meters a virtually maintenance free flow measurement solution
FLEXIM flow meters are capable of both liquid and gas measurement (including wet gas)
