The HyQuant difference.

More insight without changing or adding sensors

With a simple software upgrade, customers with a level or velocity HyQuant radar (L or V) can convert to a level AND velocity HyQuant L+V without technical intervention, returning the equipment, purchasing additional sensors or making modifications to the housing.

Seamless integration and configuration

Equipped with highly intuitive interfaces, HyQuant sensors connect fluidly to any KISTERS or third-party device via SDI-12 protocols or Modbus interfaces – making it easy to capture, analyse and share data at highly precise levels.

Ultimate precision and reliability

HyQuant’s innovative user-adjustable filters, paired with 60 GHz radars and specialised antennas, provide accurate data collection. Rigorously field-tested, they ensure reliable and consistent performance across the entire measurement range over the long term. over the long term.

Affordable without compromise

Thanks to their superior longevity and robust flood-resistant design, HyQuant delivers unparalleled value compared to other sensors. Packed with features and delivered with mounting brackets and cables, they provide exceptional price-to-performance ratio.

Simple installation

Lightweight design and included, optional mounting accessories, make HyQuant sensors quick and easy for anyone to install anywhere. Whatever the depth, conditions or existing infrastructure.

Built to last

Compact, fully submersible and manufactured from environmentally-resistant materials, HyQuant sensors are made to stand the test of time. They’re dust, water and shock-proof and are IP68 rated.

Accurate, adaptable and contactless.

Radar sensors remain unaffected by the climatic conditions and other influences between the sensor and the water surface. They can measure right up to the face of the sensor, enabling measurements even during flooding, which is distinct from other non-contact technologies with larger dead zones.

Versatile applications.

Flood forecasting and early warning

Authorities implement mitigation measures to protect communities from flood risks by using HyQuant to actively monitor river flows and levels in near real time.

Environmental balance

Water level, velocity and discharge data provide insight into historical water behaviour during specific events over time, supporting conservation efforts related to aquatic life, water quality and ecosystem health.

Management and use of water resources

Data on water use for drinking, irrigation, hydropower and cooling supports better decision-making on equitable access to scarce resources, increased revenues, reduced costs and improved risk management.

Linking quantity and quality

Understanding water flow and levels is essential to assess the impact of runoff and pollutant flow on water quality, the influence of flow on flooding, stream geomorphology and aquatic life.

Navigation and transport

Assessing the appropriate flow and velocity of a river and its drought helps to keep waterways safe for navigation and shipping, especially for larger vessels and cargo ships.

Engineering

Engineers and infrastructure designers rely on hydrological and hydraulic modelling for the design of bridges, culverts, dams and river-related infrastructure to ensure the structural safety under extreme weather conditions.

Research

Water level and velocity data helps scientists, researchers, hydrologists and climatologists study hydrology, climate patterns, environmental change and river behaviour.

With HyQuant, the challenge was to build a water level radar that would be as close as possible to a perfect match for field technicians, professional hydrographers and automated early warning systems alike. We actively listened, then got to work.
