Flow measurement on a 3.2 m pipe
Non-intrusive flow measurement on a 3.2 m concrete pipe (PCCP) at the inflow to a reservoir
Advanced leak detection cuts non-revenue water by over 50%
Non-revenue water is water that was treated and "lost" in the pipe network because of leaks and pilferage. An important Philippine water and wastewater service provider has been focusing on reducing non-revenue water (NRW) for many years. Due to targeted initiatives in water loss recovery and the application of state-of-the-art leak detection equipment, the company has brought DMA NRW down to an average of 29.78 percent in 2018 from 66 percent in 2006.

Product Solutions
The Flexim FLUXUS F532WD Series non-intrusive ultrasonic flow meter is the ideal solution for metering points in the drinking water network. Due to the use of its clamp-on technology, the FLUXUS F532WD Series enables a very simple and cost-effective installation of flow measurement points within an existing water supply network. The Flexim FLUXUS F532 WD Series belongs to the most reliable and accurate non-intrusive ultrasonic flow metering systems - it even measures flow rates as low as 0.03 ft per sec. The transducers are fixed to the pipe with broad stainless steel straps and secured in robust stainless steel housings. The transducers have IP68 protection and reinforced transducer cables.
- Extremely accurate down to flow velocities as low as 0.01 m/s
- No zero calibration needed and permanently drift-free
- Permanent coupling pads
Fluid Type
Water and water/glycol mixtures
Accuracy
Measurement uncertainty of the measuring system (volumetric flow rate): ±0.3 of reading ±0.005 m/s ( ±0.02 ft/s)
Measurement uncertainty at the measuring point (volumetric flow rate):: ±1 % of reading ±0.005 m/s (±0.02 ft/s)
Measurement uncertainty at the measuring point (volumetric flow rate):: ±1 % of reading ±0.005 m/s (±0.02 ft/s)
Repeatability
0.15 % of reading ±0,005 m/s (±0.02 ft/s)
The Flexim FLUXUS F736 Liquid Flow Meter combines highest precision digital signal processing with the well-known advantages of non-intrusive ultrasonic technology: ease of installation, retrofittable design, high accuracy, and outstanding performance. With 4 ultrasonic transducers operating in reflect mode, 8 independent ultrasonic paths traverse the liquid medium providing superior flow averaging of up to 4 planes of the pipe section. With this configuration, the F736 flow meter averages out crossflow profile effects and achieves optimum non-intrusive flow compensation for undesirable installation locations where insufficient upstream straight pipe proximity to bends, elbows or other adjacent instrumentation creates flow disturbances.
- Temperature compensated transducers - our transducers are automatically compensated for ambient temperature changes according to ANSI/ASME MFC-5.1-2011
- Easy installation without process interruptions - retrofittable and compact design
- Maintenance free - no moving parts, no wear and tear, gel/grease-free permanent transducer coupling pads
