Water and WastewaterManaging an extensive water supply network, involves dealing with various checks and flow measurements of different pipe sizes. Our ultrasonic clamp-on flowmeters help you getting the job done without interrupting the water supply.

When building a new water treatment plant, a pumping station or section of pipelines, in-line flowmeters – such as electromagnetic – can be the obvious choice. However, on existing pipelines that are not equipped with measuring instruments, and in situations that existing in-line meters are not functioning, ultrasonic clamp-on flowmeters are often a cost-effective alternative.


  • For any application containing the entire water flow : From clean to dirty water
  • For measurements of industrial waste water, water management, water supply networks and flow measurements as a result of environmental and health and safety legislation
  • Simple and fast installation
  • Non-invasive : Measuring from the outside, No process interruptions
  • Cost-saving
  • On-site measurement service

The sensors of our ultrasonic flowmeters are clamped on the exterior of the pipe. It is therefore not necessary to open up the pipe and shut down the system. This means that an interruption of your flow or production process is not necessary (anymore).

Our ultrasonic clamp-on flowmeters can be retrofitted to pipes made of various materials and with a diameter range from 3 mm to 6500 mm. This can be achieved without costly modifications to the device’s specifications. In addition, calibrations, zero flow measurements and specific pipe sizes are a thing of the past when you choose the ultrasound measurement technique.

Because the tube or pipe remains intact when installing a flowmeter, direct contact with the hazardous content of waste water is prevented. Also there is no risk of leakage.

The purchase cost is your only investment when you choose for an ultrasonic clamp-on flowmeter. While in-line flowmeters entail additional costs for engineering, process stoppages, trained personnel and all additional accessories (bolts, gaskets, washers, etc.)

Concrete applications include : monitoring water pipes and supply lines, capacity measurements, control of chemical dosing, valve and pump testing and controlling, (waste)water quality monitoring, sludge measurements, inspection and verification of in-line flowmeters, detection of leakage and blockage, comparison of feed / return, discharge measurements , flow surveys etc.
