• Usage: portable measurement
• Measurement technology: electromagnetic induction
• Measured parameters: point water velocity
• Key features: compact device with no moving parts, automatic measurement and data recording, easy data export
• Measurement range: from close to 0 m/s

ADVANTAGES

• Compact and lightweight device with no moving parts – virtually maintenance-free system
• Automatic measurement of maximum depth in the hydrometric vertical and the current depth of sensor submersion (optional)
• Automatic recording of all measurement data – the entire measurement can be completed by one person in a short time
• Measured velocity displayed in real-time – allowing control over the measurement
• Flow calculation based on international standards – saving time for post-measurement calculations
• Easy data export from the field computer to a PC via a USB connection – all values, including the LOG file, are copied
• Rugged field computer for work in harsh conditions
• Large, color display – readable even in direct sunlight
• User guide provides step-by-step assistance with device configuration and measurement – even inexperienced users can operate it
• Resistant to harsh working conditions (dust and water), IP67 protection class – the field computer will function even after full immersion
• One field computer can work with multiple MFpro sensors

APPLICATIONS

• Open channels (streams, small rivers, drainage ditches)
• Clean and heavily polluted water, sewage
• Locations with turbulent flow, heavily vegetated areas
• For calibration or control measurements

• Usage: continuous online measurement
• Key features: Accurate surface water velocity measurement, along with metadata informing about adverse conditions (e.g., vibrations, wind, sensor position changes, etc.)
• Application: non-contact water velocity measurement stations
• Built-in data logger: No
• Measurement range: 0.08 … 15 m/s

• Continuous, non-contact flow velocity measurement during low, normal, and high water levels,
• Identification of measurement values affected by sensor movement (e.g., wind, traffic) using metadata from built-in vibration and deviation sensors,
• Automatic flow direction detection,
• Reduces/eliminates interference caused by wind, rain, vibrations, or waves through advanced filtering algorithms,

• Floating objects or suspended sediments do not affect sensor operation, as it is installed above the water surface,
• Universal and movable mounting bracket allows for quick installation on structures,
• The sensor is inconspicuous due to its small size and ability to be mounted in various positions,
• Maintenance-free,

• Easy integration with systems without requiring extensive device knowledge,
• Low energy consumption; ideal for solar-powered installations,
• Easy integration with new and existing systems via SDI-12 or RS-485 interfaces,
• Compatible with OTT Prodis 2 software used for system calibration,

• open channels,
• rivers,
• streams,
• irrigation ditches,
• channels for draining technological waters,
• outlets/inlets.
