Water Flow Measurement

We provide clamp on non-invasive water flow measurement and flow meter hire/sales services.

We are excited to bring the FLUXUS® WD to the Irish market. This Flexim water meter is available now.

Alternatively, we offer on-site testing by our engineers.

The FLUXUS WD Series non-invasive ultrasonic flow meter is the ideal solution for metering points in the potable water network and has been specifically designed for customers in the water supply industry. As a FLEXIM flow meter, the WD is part of one of the most reliable and accurate non-invasive ultrasonic flow metering systems - it even accurately measures flows at velocities as low as 0.01 m/s. This makes it particularly suited to precise monitoring of minimum night flows and thus is ideal for use in leakage detection activities.

  • Precise monitoring of district metered areas (DMAs)
  • Exact capturing of even the smallest flow rates e.g. at night time
  • Measurements at buried pipes and in shafts
  • Measurements on large Prestressed Concrete Cylinder Pipes (PCCP)
  • Monitoring of pump performances

Due to the use of its clamp-on technology, the WD Series that does not require any installation 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. Designed to be installed in the field, the WD meters are equipped with IP68 transducers, permanent coupling pads and the extremely robust Variofix C mounting system. This means the transducers are suited to installation in submerged chambers and can even be directly buried.

The WD Series is installed without zero calibration and remains permanently drift-free, as do all FLEXIM flow meters. It is available with three transducer types and is suitable for inner diameters ranging from 50 to 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 such as fibre-reinforced plastic (FRP) pipes.

Your water distribution network needs the WD flow meter - contact us today to arrange a demonstration.

Flexim FLUXUS F401 flow meters - ultrasonic - for water


FLEXIM have specifically designed the F401 for applications in the municipal water and wastewater sectors. The firmware has a user-friendly menu navigation and is specifically adapted to the needs of the water industry. 

As with the F601, the clamp-on transducers mean that there is no need to enter the piping system or to interrupt supply. Measurement is ready in less than 5 minutes. This makes the F401 the ideal tool for service and maintenance activities.


  • Clean measurement process for drinking water system
  • Water loss balancing and leak detection
  • Verification of sewage lift station performance
  • Temporary monitoring of distribution and collection systems
  • Verification of pump and valve performance

The F401 is equipped with water-tight IP68 transducers, with the flow transmitter residing inside a IP67 Pelicase. When its internal battery capacity is combined with an additional external battery suitcase, the F401 offers continuous remote measurements outdoors for up to a week. The rugged water-tight transducers and transmitter mean you can have peace of mind when leaving the F401 in the field to do its work.

 The F401 is highly zero point stable and recognizes even the smallest flow rates, which makes it the ideal measurement tool for leak detection.  High measurement accuracy is offered for flow velocities of 0,01 to 25 m/s.

Pipe sizes from 25 mm to 3 m, solid contents of up to 6% by volume, as well as old and rusty steel, badly manufactured GRP or even armoured concrete pipes are not a measurement challenge to the F401.

All this makes the FLUXUS® F401 the superior companion for the daily work of water suppliers, hydrologists and engineering offices.
