Hawk sensors provide multispectral detection of hydrocarbons, harmful algal blooms (HABs), and colored dissolved organic matter (CDOM) using ultraviolet and visible fluorescence measurements. Multiple excitation wavelengths enable the sensor family to support a broad range of hydrocarbon, algal, and organic monitoring applications.

Most hydrocarbon monitoring applications use ultraviolet A (UVA) excitation, providing high sensitivity across a broad range of crude oils, refined fuels, lubricants, and produced water. For specialized applications involving light refined hydrocarbons such as gasoline and naphtha, ultraviolet B (UVB) configurations can provide enhanced sensitivity to trace surface contamination.

UVA excitation also enables continuous monitoring of CDOM, supporting earlier detection of organic surges that may influence treatment processes or disinfection by-product (DBP) formation. Multiple visible wavelengths are used to optimize detection of chlorophyll, phycocyanin, phycoerythrin, and other targeted algal pigments for real-time HAB monitoring.

Depending on the application, Hawk sensors may also detect other fluorescent substances, including certain condensates, solvents, coolants, or products containing UV tracers or dyes, subject to verification for the specific application.

BlueHawk™ sensors continuously monitor harmful algal blooms (HABs) by measuring chlorophyll and selected accessory pigments using non-contact fluorescence. Applications include freshwater and marine cyanobacteria (blue-green algae), green algae, and selected other microalgae.

Each sensor is configured for the target application and corresponding pigments. Chlorophyll provides an overall indication of algal activity, while phycocyanin and phycoerythrin enable more specific monitoring of cyanobacteria in freshwater and marine environments. Using multiple pigments provides greater specificity than chlorophyll-only monitoring.

BlueHawk sensors can also continuously monitor colored dissolved organic matter (CDOM), providing earlier visibility of organic surges that may influence source water quality or treatment processes.

Because the sensors operate without physical contact with the water, they eliminate biofouling and measurement drift while providing reliable, low-maintenance monitoring for long-term deployment.

BlueHawk sensors use patented CFRS™ technology to provide reliable non-contact monitoring across water, ground, and solid surfaces, including concrete, metal, soil, ice, and equipment surfaces with varied shapes and orientations. This enables deployment across municipal infrastructure, industrial facilities, natural water systems, and other challenging monitoring environments.

The patented coaxial optical design, large-aperture optics, and high signal-to-noise performance maximize sensitivity to trace surface contamination while helping reduce false alarms under appropriate operating conditions.

Continuous self-diagnostics, light source monitoring, and automatic excitation power compensation help maintain consistent measurement performance across changing environmental conditions.

High pulse rates enable rapid sampling, making BlueHawk sensors well suited for monitoring choppy, turbulent, and fast-moving waters where conventional monitoring methods may have limitations.

Hawk sensors combine advanced optics and electronics in a compact, lightweight, and energy-efficient design. Their compact size and low power consumption make them well suited for space-constrained or power-limited installations, including remote monitoring stations, buoys, mobile platforms, sumps, and battery- or solar-powered applications.

Standard IP68-rated enclosures provide reliable protection in demanding outdoor and industrial environments, including resistance to temporary submersion.

Optional HazLoc (Class I/II/III, ATEX) enclosures support deployment in hazardous locations where flammable gases, vapors, liquids, or combustible dust may be present, including oil and gas, petrochemical, chemical, and mining applications.

Built for long-term operation, Hawk sensors deliver reliable, low-maintenance monitoring across a wide range of environmental and industrial conditions.

BlueHawk sensors provide a detection range exceeding 33 ft (10 m), enabling non-contact monitoring from nearby or elevated structures such as intake towers, embankments, dams, bridges, piers, deep sumps, loading racks, storage tanks, and other industrial infrastructure. They can also be deployed on vessels, vehicles, and aerial drones for mobile monitoring applications.

Patented CFRS technology adapts to varying surface distances, making BlueHawk sensors well suited for monitoring reservoirs, canals, tidal zones, intake structures, and other environments with changing water levels or challenging installation conditions.

A wide detection angle (±45°) further expands installation flexibility where perpendicular mounting is impractical. It also supports pan-tilt systems for continuous scanning of large areas and surfaces up to 1,600 sq ft (150 m²) from a single monitoring location.

The broad detection angle also improves monitoring coverage across complex equipment surfaces and dynamic environments such as choppy, turbulent, or fast-moving waters.

Hawk sensors continuously monitor changing conditions and provide real-time data and alerts for hydrocarbons, harmful algal blooms (HABs), and other contamination events. Continuous monitoring supports earlier awareness, timely operational response, and informed decision-making across municipal, industrial, and environmental applications.

Built-in edge intelligence processes data directly at the sensor, enabling local alarm generation, relay activation, and other automated responses without relying on cloud or remote communications. Local processing also reduces bandwidth requirements while supporting reliable operation in remote or communication-limited environments.

Flexible wired and wireless connectivity—including RS-485 (Modbus RTU), USB, 4–20 mA, relay outputs, cellular, satellite, and low-power wide-area network (LPWAN) communications—supports integration with SCADA, PLCs, cloud platforms, and existing monitoring systems. Hawk sensors can operate independently or as part of scalable multi-sensor networks.

Optional features allow sensors to be tailored for specific applications. BlueHawk sensors can be equipped with surface distance measurement to maintain optimal detection performance across changing water levels and surface distances, while optional onboard data logging supports historical data collection even when communication with the primary monitoring network is unavailable.
