Flexim FLUXUS WD Meter Series

Non-invasive ultrasonic flow meter is the ideal solution for various applications in the water industry.


The WD Series does not affect the integrity of the pipe due to the use of its clamp-on technology. This enables a very simple and cost-effective installation of flow measurement points within an existing water supply network.

The FLUXUS WD Series belongs to the most reliable and accurate non-invasive ultrasonic flow metering systems and measures flow rates as low as 0.01 m/s. The inaccuracy of other meter technologies, such as magnetic meters, can increase so dramatically in the low flow range, that they are unsuitable for monitoring minimum night flows. For water suppliers the precise monitoring of minimum night flows is an essential part of their leakage detection activities, and the WD Series is the ideal tool for this task.

FLEXIM supplies the WD Series with the most robust mounting system on the market. The transducers are fixed to the pipe with broad stainless steel straps and secured in robust stainless steel housings. The transducers themselves have IP68 protection and reinforced transducer cables. A further unique feature of FLEXIM is that the transducers are connected with permanent coupling pads, instead of coupling gel that can deteriorate or be washed away. All this ensures the durability of the system and makes it suitable for both installations in chambers and buried installations.
