What FLOW-TRONIC does

FLOW-TRONIC S.A./N.V. is a privately-held Belgian manufacturer founded in 1989 and headquartered in Welkenraedt that designs, produces, and distributes liquid flow measurement instruments for water and wastewater applications. Its product portfolio covers open-channel and full-pipe measurement through three proprietary sensor families: RAVEN-EYE (non-contact radar area/velocity flowmeter with velocity distribution analysis and self-learning averaging), BELUGA (digital Doppler ultrasonic area/velocity sensor with real-time DSP spectral analysis), and TORPEE-MAG (hot-tap multi-electrode electromagnetic insertion flowmeter delivering 0.5% full-bore-class accuracy). Supporting products include the HYBRID system (combined radar and Doppler on one converter), ULS ultrasonic level sensors, the RLS-C21 80 GHz radar level sensor, and the IFQ Monitor 2 / IFQ Logger 2 multi-function converters with Modbus RTU and 32 GB data logging.

The company sells primarily to municipal water utilities, wastewater and sewer network operators, and industrial process-water users (cooling water, pulp and paper, chemical applications, hydropower, irrigation). Differentiators center on hot-tap installation that avoids pipe shutdown, non-contact radar and ultrasonic sensing that minimizes maintenance, multi-electrode full-profile measurement, and open-protocol integration with existing SCADA, telemetry, and GIS systems. Credentials include ISO 9001:2015 quality certification and ATEX Directive 2014/34/EU conformity for hazardous-area equipment, with documented case-study outcomes such as reducing real water loss from 32.8% to 7.6% in a Clarksville, Tennessee distribution zone.

Commercially, FLOW-TRONIC operates a direct enterprise field-sales model with technical consultation, quote-based pricing, and multi-year service contracts, supported by a global network of trained flow experts and an equipment-rental and on-site measurement-campaign service line (including the 123Flow data platform). The company is not externally funded, has no disclosed parent or institutional shareholders, and reports projects in more than 50 countries, with active go-to-market emphasis on North America (AWWA partnership, regional manager) and German-speaking Europe (DWA membership).

Products and services

• RAVEN-EYE 2+ Radar Area/Velocity Flowmeter Non-contact radar area/velocity flowmeter for open channel flow measurement. Measures flow from above the water surface without sensor contact, using velocity distribution analysis and self-learning technology to calculate average velocity. Targeted at water utilities, wastewater operators and environmental monitoring applications.
• BELUGA A/V Digital Doppler Ultrasonic Area/Velocity Flowmeter Digital acoustic area/velocity flow meter sensor using Doppler ultrasonic velocity sensing with a powerful DSP processor for real-time spectral analysis of velocity distribution across the cross-section. Used for open channel and sewer flow measurement in water and wastewater applications.
• TORPEE-MAG Multi-Electrode Electromagnetic Insertion Flowmeter Hot tap full-profile electromagnetic insertion flowmeter for full pipe applications. Multiple electrodes span the sensor body at equal area to measure and report average flow rate across the full pipe diameter, compensating for swirl and turbulent flow profiles with 0.5% accuracy. Installed without shutting down the water main. Targeted at municipal water distribution and industrial process water applications.
• IFQ Monitor 2 Multi-Function Monitor / Data Logger / Converter User-friendly monitor, data logger and converter designed for environmental and wastewater monitoring. Provides RS485 digital communication, 4-20 mA inputs/outputs, Modbus RTU communication, and 32 GB flash memory for comprehensive flow monitoring. Pairs with Flow-Tronic sensors for open channel and full pipe installations.
• IFQ Logger 2 Portable Data Logger / Converter Portable data logger and converter for environmental and wastewater flow monitoring campaigns. Provides approximately 3 months of battery autonomy at a 5-minute measurement interval. Used as the field-deployable complement to the IFQ Monitor 2 for temporary measurement campaigns.
• ULS Ultrasonic Level Sensors Ultrasonic level sensor using pulse-echo technology for continuous level monitoring of liquids in closed conduit or open channel applications. Self-contained transducer and electronic module. Used as a complementary measurement to area/velocity flowmeters and for stand-alone level monitoring.
• RLS-C21 80 GHz Radar Level Sensor 80 GHz FMCW radar level sensor for continuous level measurement of liquids and bulk solids. Maintenance-free operation with Bluetooth configuration. Used for non-contact level monitoring in water, wastewater and industrial process applications.
