Our Flagship Velocity Meter
Fluvia RC3 - Summary
The FLUVIA RC3 flow meter is a portable electromagnetic device that measures the velocity of water to determine its flow.
Its hydrodynamic shape and small probe size permits measurements close to a fluid surface, channel bed or pipeline wall, and with no moving parts, it does not retain debris - guaranteeing accuracy and reliability.
The FLUVIA RC3 can be tailored to the user’s ideal setup, meaning the units, date and time, language and data logging methods are easily changeable. An optional extra of GPS is also available which would auto set the time as well as provide accurate location information for each data point.
Electromagnetic sensor unaffected by temperature variations, density changes, sediment and water clarity
IP67 Environmental Rating
Rechargeable, 20hrs continuous use battery life
Multilingual – English, French, German, Spanish, Dutch, Danish - other languages on request
GPS, Bluetooth and GSM (Cellular network) support
Two sensor types are available
Recording of up to 12,000 data points
Customisable Set Up
The FLUVIA RC3 can be tailored to the user’s ideal setup, meaning the units, date and time, language and data logging methods are easily changed.
An optional extra of GPS is also available which will auto-set the time as well as provide accurate location information for each data point.
The FLUVIA RC3 is capable of generating a computed river flow profile, allowing more detailed analysis of a river.
Easy to Use
The user interface for the FLUVIA has been designed to be as simple as possible enabling users to quickly and effectively take accurate velocity measurements.
The unit’s IP67 rating and sturdy build means that the FLUVIA can be used in harsh environments, with the added feature of the waterproof encoder allowing easy navigation even with gloves on.
Its hydrodynamic shape and small size probe permits measurements close to fluid surface and channel bed or pipeline wall, and with no moving parts, it does not retain debris, guaranteeing accuracy and reliability.

ISO748:2007 flow calculation
Circular, rectangular and trapezoidal: Option to take 1 point, 3 points or 0.9x Vmax at the centre of the channel. It is possible to accumulate several speed measurements per point. Final calculation of average velocity and flow profile.
River: Verticals at locations of the operator's choosing, specifying position, bank width and depth. At each vertical the user may take a number of point readings (1, 2, 3, 5 or 6). The user has the option of accumulating several speed readings per point. Final calculation of average velocity and flow profile. It is possible to record each vertical and export it.

The wading rod is comprised of 50cm modular cylindrical sections, a disc at the base, a handle and an adjustable attachment point for the probe. This wading rod is best suited for use in sanitation environments because of its variable lengths, owing to its modularity, allows access to difficult-to-reach locations. Available in lengths of 1.5m or 3m, it can be extended in increments of 50cm using additional sections
