Product Feature: Flexim FLUXUS F401 Ultrasonic Flow Meter 1

FLEXIM, the leader in clamp-on ultrasonic flow measurement, has a new portable flow meter designed for long-term field measurement situations.

Depending on programming, the FLUXUS F401 can operate autonomously for long periods, up to several months. This makes it perfect for leak detection investigations and hydraulic studies – anywhere regular, long-term measurements are needed.

Built with the water and wastewater industries in mind, the clamp-on ultrasonic flow meter system has is installed without process interruption and installation only takes a few minutes. From then on, the FLUXUS F401 delivers highly accurate and highly repeatable measurements that are not affected by drift. Its low flow capability (down to 0.01 m/s) makes the FLUXUS F401 perfectly suited for monitoring drinking water networks, where low flow velocities are common. The combination of strong signal output and internal noise suppression technology allows the FLUXUS F401 to be used confidently on very large pipes and challenging materials such as rusty steel, badly manufactured GRP, or even armored concrete pipes. These situations are not a metering challenge to the FLUXUS F401.

The product is designed from the ground up for regular heavy duty use in very rough conditions. All parts of the FLUXUS F401 are built to last. Metal sheathing of  protects the the transducer cable ends from tight bending as well as cuts, and ensures tangle-free operation. A six meter cable length of the IP68 transducer accommodates installation of the transducers in deep manholes, with the transmitter being safely located in the upper part of the manhole. The transmitter itself is housed in a robust case with IP67 protection.

The new FLEXIM FLUXUS F401 is ideal for the daily needs of water suppliers, hydrologists and engineering offices. For more information or to request a quote, contact our flow and safety technologies team!
