The FLUXUS F401 heavy duty portable Ultrasonic Flow Meter is the ideal flow meter for long-term measurement campaigns in the field. Depending on the programmed measurement interval the FLUXUS F401 can operate autonomously for several months. This makes it suitable for leak detection campaigns and hydraulic studies, where regular measurements are needed over a longer period of time.
The clamp-on ultrasonic system has been designed specially to meet the needs of the water and wastewater industries. The FLUXUS F401 is installed without process interruption and the installation can be completed within a few minutes.
Thereafter, it delivers accurate and highly repeatable measurements that are not affected by drift. Due to its excellent low flow capability (down to 0.01 m/s), the FLUXUS F401 is ideally suited for monitoring drinking water networks, in which low flow velocities are common.
The strong signal output and the noise suppression technology make it possible to use the FLUXUS F401 on very large pipes and challenging materials: Old and rusty steel, badly manufactured GRP or even armored concrete pipes (independent of lining and build-up inside the pipe) are not a metering challenge to the FLUXUS F401.
All parts of the FLUXUS F401 have been designed to ensure utmost robustness for regular heavy duty use in rough conditions. The metal sheathing of the transducer cable ends protects them against strong bending or cuts and ensures tangle-free operation.
The six-meter cable length of the IP68 transducers allows for the installation of the transducers even in deep manholes, whereby the transmitter can be placed in the upper part of the manhole. The transmitter is housed in a robust case and has IP67 protection.
All this makes the FLUXUS F401 the ideal companion for the daily work of water suppliers, hydrologists, and engineering offices.
Advantages
Several months operation time
The FLUXUS® F401 is the ideal flow meter for long-term measurement campaigns in the field. Depending on the programmed measurement interval the FLUXUS® F401 can operate autonomously for several months. This makes it suitable for leak detection campaigns and hydraulic studies, where regular measurements are needed over a longer period of time, but it is not planned to install a permanent ultrasound flow meter.
No signal deterioration
As the FLUXUS® F401 is designed for long-term field operation, it is supplied with permanent coupling pads in addition to coupling gel. For short-term measurements coupling gel is suitable, but not for semi-permanent field installations. In the field extreme heat or periodic submersion of the transducers can lead to depletion of the coupling gel, which results in signal deterioration or dropout. The permanent coupling pads of the FLUXUS® F401 guarantee an excellent acoustic coupling no matter what the field conditions are.
Extremely robust design
All parts of the FLUXUS® F401 have been designed to ensure utmost robustness for regular heavy duty use in rough conditions. The metal sheathing of the transducer cable ends protects them against strong bending or cuts and ensures tangle-free operation. The six meter cable length of the IP68 transducers allows for the installation of the transducers even in deep manholes, whereby the transmitter can be placed in the upper part of the manhole. The transmitter is housed in a robust case and has IP67 protection.
