Flexim
From liquids to gases, Emerson’s Flexim non-intrusive, clamp-on ultrasonic flow measurement and refractometer technologies measure virtually anything that flows. Innovative technology and accuracy makes us an industry leader in flow measurement solutions. Clamp-on FLUXUS® flow meters dependably measure the flow of almost all fluids, whether liquid or gas, and excel in measuring steam, without interrupting operations. The WaveInjector® mounting fixture can operate in extreme temperatures, extending the application range of non-intrusive ultrasonic technology to temperatures from -200 to +630 °C (-328 to +1166 °F). And our measuring instruments designed for use in explosive environments, ensure accuracy, safety, and reliability in all conditions.

______________________
The Flexim FLUXUS F601 is measurement ready in 5 minutes and is the portable clamp-on flow meter of choice for servicing and maintenance activities, the control and auditing of measurement points not covered by permanent meters, or even the temporary replacement of permanently installed flow meters. With its Li-Ion battery, the F601 allows for over 14 hours of autonomous measurement. Matched and paired transducers as well as sophisticated algorithms correct for pipe wall echoes and wrong transducer positioning, thus ensuring reliable and highly accurate measurements - even under the most demanding application conditions.
- Rugged for its usage in rough industrial environments - with two flow channels as standard
- Fast measurement: No zero point calibration necessary thanks to Plug & Play transducer recognition (EPROM)
- Maximum flexibility for a broad application range with only two pairs of transducers
- Bi-directional measurement for nearly all pipe materials and nearly all liquid media - huge internal database
- Ideal solution also for thermal energy / BTU metering
- Accurate and reliable measurement even under difficult flow conditions due to the new HybridTrek mode
- High degree of flexibility, e.g. for energy metering, data logging, various In-/Outputs, recording of ext. pressure data

lexim FLUXUS F721 WD Stationary Ultrasonic Water Flow Meter
______________________
The Flexim FLUXUS F721 WD non-intrusive ultrasonic flow meter is the perfect flow measurement solution for drinking water and wastewater applications. It enables a very simple and cost-effective clamp-on installation of flow measurement points within an existing water supply and wastewater infrastructure. The Flexim FLUXUS F721 WD belongs to the most reliable and accurate non-intrusive ultrasonic flow metering systems. It even measures flow velocities as low as 0.01 m/s (0.03 ft/s) – ideal for leak detection and night flow measurements. Thanks to permanent coupling of the transducers onto the pipe and the IP68 protection, it is suitable for installations in chambers and for buried or flooded installations. Compared to the F532 WD, the F721 WD serves pipes with diameters of over 2000 mm (79 in), offers dual channel measurements and comprehensive communication combinations.
- Extremely accurate down to flow velocities as low as 0.01 m/s (0.03 ft/s).
- No zero-calibration needed and permanently drift-free.
- Permanent coupling foil.
- IP68 transducers.
- Transducers can be permanently buried (no chamber required).
- Reliable and accurate flow measurement.
- Low installation costs.
- Built to last.
- Works on challenging pipe material like, for example, PCCP and cement.
