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.

the HyQuant difference

Smarter sensor

Get more insight without adding or replacing sensors at the same site. A simple software upgrade transforms a HyQuant level only or velocity only sensor into a combined level and velocity sensor — without technical intervention. Also choose the option to upgrade a HyQuant level and velocity sensor to calculate discharge. More water monitoring. More data to inform decisions. Less hassle replacing or returning devices.

Compact powerhouse.

Every technical specification is field-tested and proven to ≤2 mm accuracy with consistent and reliable performance over the full measurement range, across various distances and over long periods of time.

It offers one of the most efficient power consumptions available of 15 mA at 12V. It uses the FMCW measurement principle, only seen in a few water level radars.

Meets all necessary criteria for environmental users.

HyQuant L is power-efficient with a IP68 rating and built-in filter algorithms for local adaptation. Its compact, lightweight design allows for easy installations and reduces chances of vandalism. The sensor is specifically designed for use in the field, where conditions require robust housing, low power use and maintenance demands. Get reliability even in harsh and remote deployments.

Integrate, communicate and configure

HyQuant sensors have an intuitive interface and connect to any KISTERS data logger, third-party logger, or other device via SDI-12 or Modbus interface. Configure sensors via Wi-Fi connection and SDI-12, or connect to PCs via SDI-12 using a common USB adapter.

Affordable without compromise

HyQuant delivers unparalleled value in water monitoring by balancing superior performance and cost-effectiveness. The budget-friendly sensor, equipped with special features, requires minimal maintenance. Each device comes complete with a mounting bracket and cable, ensuring an exceptional price-to-performance ratio.

Simple installation, low maintenance

The streamlined, lightweight sensor — along with the included tilt and swivel mounting bracket — facilitates easy installation and proper positioning. Mount on various support structures, ranging from bridges or purpose-built structures to arms and outriggers. Installation with existing infrastructure is simple and can be accomplished by anyone.

Accurate, contactless & radar.

Non-contact radar sensors remain unaffected by the climatic conditions and other influences between the device and the water surface. Measure right up to the face of the sensor, recording measurements even during flooding. Overcome other challenges and larger dead zones experienced with competing non-contact technologies.

Want to learn more about radar technology?

Gain insights from the latest development in water monitoring as experts Stefan Siedschlag, Dr. Anton Felder and Edgar Wetzel explain the opportunities & limitations of radar sensors over open channels.

With HyQuant, the challenge was not to build a water level radar -- but to come as close as possible to a perfect tool for professional hydrographers and flood warning system managers alike. We listened attentively, assessed the wealth of first-hand insights, and only then we got to work.
