dBR Radar series
Pulsar dBR Radar series – Non-contacting Radar level sensors
The Pulsar dBR radar series of transducers is a range of Radar level sensors that are ideal for difficult applications such as high temperatures, applications subject to foam or atmospheric changes, or applications with harsh chemicals that give off vapors.
Radar level sensors from Pulsar Measurement are complimentary to the Ultrasonic range of sensors and gives end users a complete choice of technology based on the needs of their application.
Linear Frequency Modulation (LFM) processing enables our radar level sensors to have a strong signal-to-noise ratio and excellent resolution, giving the sensors significant advantages over pulsed radar systems. Featuring unique digital echo processing technology from Pulsar Measurement, our range of radar level sensors are able to ‘zone in’ on the true level, and keep focused on the correct echo – even when there is competing noise in the measurement path.
The dBR radar series of level sensors are suitable for chemical level measurement, tank level measurement, industrial level monitoring, hazardous applications, applications with high atmospheric changes, high-temperature applications, or applications subject to foam.

When Should You Consider Radar Technology?
There isn’t a lot of difference between ultrasonic and radar technology,
however, there are some applications where radar is better suited.
- Longer Range Open Channel Flow
- High-Temperature Applications
Where the surface of the substance being measured is hot, it can create a
temperature gradient above the surface. This will affect the speed of sound
and creates an inconsistent ultrasonic signal. - Acoustic Noise Interface
Electrical noise interference can be ignored but sometimes acoustic noise can interfere with the signal. By using a radar sensor for these applications, it can eliminate this rare
occurrence. - Foamy Applications
Radar measurement will produce more stable results than ultrasonic sensors with limited acoustic power on foamy applications. - Dosing Plants & IBC’s
One clear advantage of radar is that it can read through the container wall. - Digester’s
Ultrasonic measurement has struggled with the inability to measure reliably within the methane-rich, elevated temperature, and pressurized environment of a sludge digester; radar measurement offers an easy way to measure levels within the digester’s and with a standard set of communications
and protocols that communicate with the rest of the site.
