LTR51 Self-Adjusting “Smart” Radar Level Sensor

The LTR51 Series radar level sensors are designed for applications requiring non-contact level measurement, in which ultrasonic level measurement is not acceptable. 

The LTR51 Series radar technology can be adjusted for variables such as materials to be measured, vessel configuration, and system interface. 

These sensors are ideal when vapor, dust, or a foaming surface prevents ultrasonic-wave measurements. 

The LTR51 Series radar sensors can detect the level under a layer of light dust or airy foam, but if the dust particle size increases, or if the foam or dust gets thick, they will no longer detect the liquid level. 

Instead, the level of the dust or foam will be measured. Internal piping, deposits on the antenna, multiple reflections, or reflections from the wall can interfere with the proper operation of the radar sensor. 

Other sources of interference are rat-holing and bridging of solids, as well as angled process material surfaces that can reflect the radar beam away from the receiver.
