Centurion Guided Radar Level Transmitter

The Award-Winning Centurion Guided Radar (CGR) Level Transmitter is ideal for the measurement of liquids, sludge, powders and granules to a range of 38m (124ft) for level and interface measurement. This technology is not affected by pressure, temperature, viscosity, vacuum, foam, dust, changes in dielectric constant or coating of the probe. HAWK’s CGR won the prestigious Chemical Processing 2021 Vaaleer Awards. HAWK's CGR is the first and only guided wave radar on the market to feature Power over Ethernet (PoE) communications. The advantages to PoE connectivity are secure in-plant and remote monitoring, as well as remote sensor setup, diagnostics and troubleshooting abilities.

Customer Testimonial

“Our family oil and gas exploration and production company has been using Hawk CGR guided wave radar tank level sensors for over six years now, and the devices are highly reliable and accurate. The setup on the latest version is incredibly simple and fast with the LCD screen and on-device menu navigation buttons—it took less than 10 minutes per device to configure. The LCD screens with tank level readouts have been extremely helpful as we no longer have to rely on manual tank gauging. These readouts make it easy for the pumper to monitor tank levels in real time while circulating bottoms off of oil tanks, or otherwise moving fluid from one tank to another. The low power consumption allows us to run multiple sensors off of solar panels. Technical support has been very responsive and helpful. We would highly recommend the Hawk CGR tank level sensors to anyone looking for a stable, accurate, and easy-to-use tank level monitoring solution.” -Adam, Midland, TX [Oil & Gas Industry]

Principle of Operation

Guided-wave technology sends the radar pulse down a probe to measure either liquids, solids or a low dielectric to high dielectric Interface level. The pulse hits the surface and / or Interface and is reflected back up the probe to the sensor, where the transit time is translated into a distance using time of fight and time expansion. The amplitude of the reflection depends on the dielectric constant of the product.
