The Flexim FLUXUS F401 is the ideal flow meter for long-term measurement campaigns in the field. These heavy-duty flow meters can be 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 0.03 ft/s), the FLUXUS F401 is ideally suited as a drinking water flow meter, in which low flow velocities are common. The strong signal output and the noise suppression technology make it possible to use on very large pipes and challenging materials such as old and rusty steel, badly manufactured GRP or even armored concrete pipes.
