Small but mighty powerful
Easily install and maintain these cost-effective HyQuant sensors in large numbers to support water-critical operations.
Location-specific insights can inform decisions about equitable access to scarce resources, improve risk management, reduce operating costs, and maximize power generation.
Non-contact continuous monitoring of water level is essential — especially if you operate flood warning systems, forecast water supply, or rely on waterway transport.
HyQuant and its alarm settings quickly detect sudden changes in water level and velocity, helping to triage drainage, emergency or maintenance issues.

HyQuant L: SDI-12 water level radar sensor
Fitted with IP68 rating, FMCW (Frequency Modulated Continuous Wave) technology, and available in two versions of 20m and 50m range, HyQuant L supplies measurements with ultimate precision within a user-defined site-specific validity range.
Key features:
- High data quality under any conditions: ≤ 2 mm accuracy over the entire measurement range
- SDI-12 and Modbus interface.
- No hidden additional costs. Mounting bracket; cable; SDI-12, Modbus and Wi-Fi interface; and configuration software included.
- Option: Upgrade from a level only sensor to a combined level and velocity sensor, or upgrade to a discharge sensor – without technical intervention. Simply upgrade via software.

HyQuant V: Surface velocity radar sensor
The first water velocity radar sensor to use the 60 GHz frequency band, HyQuant V delivers higher resolution, accuracy, IP 68 protection and low power consumption at an attractive price.
Key features:
- Radar on-chip technology simplifies sensor positioning, eliminating the need to manually adjust sensor orientation to find the optimum radar beam angle.
- Small beam width and short wavelength capture continuous surface velocity data in low, normal, and high flow conditions with superior sensitivity.
- SDI-12 and Modbus interface.
- No hidden additional costs. Mounting bracket; cable; SDI-12, Modbus and Wi-Fi interface; and configuration software included.
- Option: Upgrade from a velocity only sensor to a combined level and velocity sensor, or upgrade to a discharge sensor – without technical intervention. Simply upgrade via software.

HyQuant L+V: world’s first water level & surface velocity radar
The IP68-rated HyQuant L + V utilizes innovative Doppler and FMCW (Frequency Modulated Continuous Wave) technologies into the smallest casing. Weighing 1.15 kg or 2.5 lb, this radar sensor is the smallest of its kind – avoiding attention and lessening risk of vandalism.
Key features:
- Radar on-chip technology with special antennas is designed for simultaneous water level and velocity data acquisition. Leverage the stream data to determine discharge.
- Exceptional data quality achieved through high resolution, optimized sensing area and continuous measurement in all stage and flow conditions.
- SDI-12 and Modbus interface.
- No hidden additional costs. Mounting bracket; cable; SDI-12, Modbus and Wi-Fi interface; and configuration software included.
- Option: Upgrade from a combined level and velocity sensor to a discharge sensor without technical intervention. Upgrade software to compute discharge.
