Technical Specification
FLUXUS® F401 H2O
Ultrasonic Measurement of Water Flow
Portable, high accuracy, non-intrusive flow measurement
Features
• Non-intrusive flow measurement with high measuring
accuracy for portable use
• Precise bi-directional, highly dynamic flow measurement
• Water-tight transducers (IP68) are characterised by
their high robustness
• User-friendly menu navigation - the firmware is specifically adapted to the needs of the water industry
For nominal diameters of 25 to 3100 mm and for flow
velocities of 0.01 to 25 m/s
• Digital signal processor (DSP) and signal processing
ensure stable and reliable results even under difficult
measurement conditions
• High measuring accuracy, even at low flow velocities
• Adherence to AWWA manual M36
FLUXUS F401 H2O
Applications
• Water and wastewater applications
• Clean measurement process for drinking water
systems
• Leak detection
• Water loss balancing
• Verification of sewage lift station performance
• Temporary monitoring of distribution and collection
systems
• Verification of pump and valve performance
