Non-Intrusive, Clamp-on Ultrasonic Technologies

Emerson’s Flexim Non-Intrusive Ultrasonic flow measurement technologies measure virtually anything that flows, liquids as well as gases. Our proprietary clamp-on ultrasonic flow meters enable operators to simply attach the transducer to the outside of the pipe – without any interruption to operations or any risk of leakage.  As our products meet the highest requirements of industrial production, safety and the highest level of plant availability on the other operators can easily measure flow anywhere.

    Measurement Principles

    FLUXUS® clamp-on ultrasonic systems determine the volume flow according to the transit-time difference method. Since the ultrasonic signal that is irradiated into the pipe is carried by the medium flowing inside, a time delay occurs between the acoustic transit time both with and against the flow of direction. This time delay can be measured very accurately. The measuring transmitter calculates the volume flowrate based on the parameters input for the pipe geometry and the physical properties of the medium stored in the internal database.

    Proven Accuracy

    The reliability and accuracy of measuring systems depend on the quality of their manufacturing and calibration. Consistent quality management according to DIN ISO 9001 is essential for Flexim, which has a calibration laboratory certified to ISO/IEC 17025:2018. Calibration is carried out on individual calibration equipment according to national standards. Flexim calibrates pairs of transducers and measuring transmitters independently of one another so that the narrowly defined measurement uncertainties are always observed, regardless of which transducers are used.

    Non-Intrusive Ultrasonic

    The Flexim FLUXUS® Non-Intrusive Ultrasonic Flow Meters are used wherever something flows. Clamp-on technology opens up an unrivaled wide range of applications as the FLUXUS device reliably measures the flow of virtually any medium, be it liquid or gas, regardless of the flow direction (bidirectional) and over an extremely wide measuring range. Due to its practical advantages, external flow measurement with clamp-on ultrasonic transducers has become a standard measuring technique in a broad range of industries and applications.

    Diagnostic Insight: Advanced Meter Verification

    Advanced Meter Verification (AMV) allows you to check the health of your Flexim flow measurement device directly onsite without the need of process interruption. This flow meter verification solution saves cost while ensuring the performance of your non-invasive flow measurement. The continuous acquisition and permanent storage of diagnostic values by the transmitter enables regular verification. Based on this data, maintenance can be planned, and unexpected failures can be avoided. Operators can automatically generate a flow meter verification report provides the documentation required for your quality management system.
