FLEXIM - FLUXUS WD Series - Stationary Ultrasonic Water Flow Meter

Stationary Ultrasonic Water Flow Meter

The FLUXUS WD Series non-invasive ultrasonic flow meter is the ideal solution for metering points in the drinking water netork.
Due to the use of its clamp-on technology, the WD Series that does not require any work that affects the integrity of the pipe. 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 - it even measures flow rates as low as 0.01 m/s. The inaccuracy of other meter technologies, such as magnetive inductive meters, can increase so dramatically in the low flow range, that they are unsuitable for monitoring minimum night flows. But 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.

There is no method of zero drift correction for our instruments – because they just don’t drift. This also applies to the WD Series that is installed without zero calibration and remains drift-free, permanently. FLEXIM is the only company that accomplishes this, thanks to its unique combination of matched piezo-transducers and advanced factory calibration.

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.

The WD meter is available with three transducer types and is suitable for inner diameters ranging from 50 ... 6500 mm. The strong signal output and noise suppression technology make it possible to use the WD Series on all pipe materials, even on such challenging ones as fiber-reinforced plastic (FRP) pipes. The outstanding performance of FLEXIM is shown by thousands of references worldwide.
