FLUXUS F532 WD – FLEXIM Technology at the Right Price

Non-Invasive Ultrasonic Flow and Temperature Measurement without having to cut pipe

Permanently installed clamp-on measuring system for water and wastewater processes.


  • All water applications from the reservoir to the tap, and everything in-between
  • All chemical addition applications for water treatment, Sodium Bisulfite, Sodium Hypo, Hydrofluorosilicic Acid, Sodium Hydroxide, Ferric Chloride

With the innovative FLUXUS F532 WD, FLEXIM introduces a flowmeter specifically designed for applications in water treatment. The compact measuring system is able to record flow rates non-invasively with clamp-on ultrasonic transducers mounted on the outside of the pipe, making it possible to set up flow measuring points on existing pipes, without interruption to operations.

Making these measurement is not new for FLEXIM, what is new is the F532 WD, designed specifically for this market and at a price point below most competing technologies. Traditional chemical feed meters, require exotic alloys which are expensive, with FLEXIM we just clamp onto your proven pipe material. Moreover, the F532 WD can measure very low flow rates, which magnetic meters cannot even detect.

The installation does not require any modification of the pipe and no supply interruption whatsoever. Ultrasonic transducers are NEMA 6P rated, stainless steel mounting rails and durable permanent coupling pads, allow the transducers to be installed below grade, and even permanently buried.

The FLUXUS F532WD ultrasonic system offers the additional benefit of being able to accurately determine the temperature in the water. Temperature determination is based on the measurement of the speed of sound and is also carried out non-invasively with the same ultrasonic transducers as used for flow measurement. This offers water suppliers the opportunity to monitor the increasing risk of bacterial contamination associated with higher temperatures without any extra effort or cost.

The FLUXUS WD Series is the most reliable and accurate non-invasive ultrasonic flow metering systems on the market.


  • Highly accurate, non-invasive flow and temperature measurement, irrespective of the flow direction (bidirectional), with outstanding measurement dynamics, excellent zero-point stability and high repeatability of the measurement results.
  • Easy to implement solutions for wireless remote data transmission (i.e. LoRaWAN, etc.).
  • Measures flow rates as low as 0.03 feet per second.
  • No zero calibration needed and permanently drift-free.
  • Suitable for outer diameters ranging from 3/8″ up to 80″.
  • The WD Series can be used on all pipe materials, even on challenging fiber-reinforced plastic (FRP) pipes.
