Ductile iron pipes are relatively inexpensive and long lasting, so they are quite common in waste water installations, but they are not a problem for Fluxus clamp-on ultrasonic meters.

Ductile iron pipes are quite common in waste water installations: they are relatively inexpensive and last a long time. For ultrasonic flow measurement, such pipes can present quite a problem. Clamp-on ultrasonic flow meters are the ideal solution in cases where the flow disruption is impossible, or very expensive.

Unfortunately, ductile iron tends to attenuate sonic energy, and it can be a problem for clamp-on ultrasonic flowmeters..

If such pipes are furthermore lined with cement, the attenuation becomes even stronger, thus presenting a considerable problem.

Recently, a dual channel Fluxus ADM 7407 was successfully installed in a waste water treatment plant in New Jersey, where the facility operator needed to measure the influent and effluent of the primary treatment portion of the plant.

Thanks to its high output voltage and power, Fluxus succeeded where all other tested ultrasonic clamp-on meters had failed.

After a series of tests, Fluxus meters were permanently installed on both wastewater lines.

The installation went flawlessly - with no flow interruptions, because the unit was installed onto fully operational pipework.
