To preserve and manage a precious coastal underground water area in Australia, the local water authority has developed unique mechanisms to supply river water directly to irrigators and continue to improve and conserve groundwater. At pump stations, surface water is pumped from the local river and supplied to farmers. To reduce the overall consumption at the pump stations, one of the plants underwent an upgrade project which entailed the installation of the pumps with variable speed drives (VSDs) and clamp-on flow meters on the rising mains. The operators investigated methods to retrofit old pipes with reliable and accurate measuring instrumentation. Flow measurement would need to be possible even on old pipes which were buried for the most part and only partially accessible.
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.
The Flexim FLUXUS F401 is the ideal flow meter for long-term measurement campaigns in the field. These heavy-duty flow meters can be installed without process interruption and the installation can be completed within a few minutes. Thereafter, it delivers accurate and highly repeatable measurements that are not affected by drift. Due to its excellent low flow capability (down to 0.03 ft/s), the FLUXUS F401 is ideally suited as a drinking water flow meter, in which low flow velocities are common. The strong signal output and the noise suppression technology make it possible to use on very large pipes and challenging materials such as old and rusty steel, badly manufactured GRP or even armored concrete pipes.
