Seawater Flow Measurement
Flow Measurement of Seawater Pipelines at Desalination Plants
Flow control of seawater pipelines
Many mining operations, especially in areas with limited freshwater sources, turn to seawater as an abundant source of water. However, seawater is salty and not directly usable for most mining processes. To make seawater usable for ore processing, cooling machinery, dust suppression, and other essential functions, mining companies install desalination plants. It is essential to have control over these pipelines, but large pipe sizes, intensive scaling, and constant corrosion make it impossible for most of the flow metering solutions to succeed in these conditions, but not for low maintenance clamp-on ultrasonic flow meters, which are designed to target these kind of applications.

Product Solutions
The Flexim FLUXUS F731 is a technological breakthrough in the ultrasonic clamp-on volume and mass flow measurement of liquids. Highly sophisticated signal filters, faster than ever processing capacities and advanced measurement algorithms make the FLUXUS F731 ultrasonic clamp-on liquid flow meter the standard-setting measuring solution for any industrial application. With the new Synchronised Channel Averaging (SCA) method and flow profile correction, the F731 ultrasonic flowmeter is ready for the most challenging conditions.
- Accuracy and repeatability - exceptional reliability and accuracy at high and low flows due to matched, calibrated and temperature compensated transducers, advanced signal processing capabilities and diagnostics.
- Easy installation without process interruptions - an externally mounted system means no need for process interruptions or additional engineering costs.
- Maintenance-free - no contact with flowing media results in a completely maintenance- free and durable metering solution to withstand even the harshest environments.

The Flexim FLUXUS F731 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 F731 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 F731 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.

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 up to 25 hours of autonomous measurement. Matched and paired transducers, as well as sophisticated algorithms to correctly identify pipe wall echoes and wrong transducer positioning, ensure reliable and highly accurate measurements - even under the most demanding application conditions.
