The MiniWave is a compact, loop-powered ultrasonic level transmitter for continuous measurement of liquids. As a price leader, it does not compromise on good value; and provides effortless and intuitive operation. Easy and flexible mounting combined with high chemical compatibility and 12m (40ft) measuring range makes the MiniWave suitable in multiple applications in all industries.
Gladiator Gen 3 Microwave Switch
The Gladiator Gen 3 Microwave Switch provides reliable non-contact detection for blocked chutes, point level, anti-collision, machinery protection and material presence applications. A high-power microwave beam operates between a sender and receiver to detect material or objects passing between two points.
ACURAGE™ with GWR
The patented ACURAGE™ is the industry's first single chamber sight glass with Guided Wave Radar. Proudly made in the USA, this unique, ASME approved level measuring instrument displays the level of process fluids in real-time via digital display and built-in sight glass tube. The ACURAGE™ features a built-in safety ball check system to protect the operator from accidental spillage of process liquid in the unlikely event of glass breakage.
Gladiator G1 Microwave Switch
The Gladiator G1 (1") Microwave Switch can be used for blockage detection, barrier detection, point level measurement, and detection of objects or material between two points.
Gladiator Acoustic Switch

Gladiator Conductivity Level Switch
The Gladiator Smart Conductivity Switch is a third-generation, state-of-the-art level probe, designed to operate in tough industrial environments. The probe of the Conductivity Switch forms one part of an electric circuit, with the vessel wall or a reference probe making another part. A conductive liquid between the probe and the vessel wall (or between the probe and the reference probe) links the two parts of the circuit and the output will switch in response. The output has adjustable hysteresis and delays for on or off switching. A test function is available to remotely confirm the probe integrity by switching the relay contacts. The Gladiator Smart Switch Series includes communications capability for remote adjustment, control and monitoring.
Gladiator Admittance Level Switch
The Gladiator Admittance Smart Switch is point level switch for liquids, solids and powders. The unit is suitable for a broad range of products and dielectric constants up to high temperature of 450°C (842°F).
ORCA Bed Level System
The ORCA Sonar Bed Level System will measure up to two density interfaces simultaneously. Typically these are bed levels / RAS blanket and floc / fluff layers. The sonar produces a high power concentrated beam, and provides critical plant control to optimize performance.
Gladiator Vibration Smart Switch Series
A stainless steel tuning fork is driven by piezo ceramic elements, causing it to vibrate at its resonant frequency. When the material to be detected covers the fork, vibrations are damped. The changed vibration is sensed electronically, and the processed signal is used to switch a relay for indication or control purposes.
Sultan Acoustic Wave Level Transmitter - Power over Ethernet (PoE) Series
The Sultan Acoustic Wave Level Transmitter with Power over Ethernet (PoE) is ideal for level, flow, positioning and collision protection to a distance of 60m (196ft) or up to 180m (588ft) for extended ranges. HAWK is the only company on the market to offer PoE connectivity for Acoustic Wave Level Measurement. This rugged, self-cleaning sensor requires zero maintenance and is ideal for measuring level of liquids, slurries, and solids. The combination of low frequency, high power, and signal processing (Adaptive Gain Technology) creates one of the world's most reliable level devices available on the market.

In the water, wastewater industry process conditions will vary greatly between a primary sedimentation tank, secondary/final clarifier, and a gravity thickener. Thickener bed levels, secondary RAS blanket, flocculent blanket, etc, all have different densities and the water above these interface levels are subject to different process conditions that change.
Magnetic Level Gauge (MLG)
The HAWK Magnetic Level Gauge (MLG) is widely applied in the monitoring and process control of liquid level and interface for many industries; such as petroleum, chemical, power, paper, metallurgy, water treatment etc.
Frequently Asked Questions About Liquid Level Control
Why are HAWK’s level control solutions better for "problem" materials like foam or dust?
Standard level sensors often fail in high-dust or foamy environments due to signal interference. HAWK is superior because we utilize Adaptive Gain Technology and low-frequency Acoustic Wave sensors that "punch through" dust and foam rather than reflecting off them. This ensures you get a true level reading where other sensors only see surface noise.
Can HAWK's level measurement systems be monitored remotely?
Yes. HAWK is the first and only company to offer Power over Ethernet (PoE) connectivity for Acoustic Wave and Guided Wave Radar sensors. This allows for secure, real-time monitoring, remote diagnostics, and troubleshooting via our HawkEye365 portal, eliminating the need for expensive site visits.
How do I choose between Radar and Ultrasonic level control?
Generally, Radar (like our Senator series) is preferred for high-pressure, high-temperature, or vacuum applications. Ultrasonic/Acoustic Wave (like our Sultan series) is superior for long-range solids where dust is a major factor.
