Flexar® Guided Wave Radar Level Sensor
Available from Monitor Technologies LLC
Monitor Technologies' Flexar® continuous level measurement system is a smart guided wave radar device used for monitoring the level of powders, granules and other bulk solids. It has proven to reliably work in dusty conditions. It is also suitable for use with a variety of liquids.
Flexar® smart guided wave radar level sensors and transmitters operate using TDR (time domain reflectometry) principles. In the application of TDR for process level measurement, micro-pulses are continuously transmitted along a probe or “wave guide” at the speed of light. As soon as the pulses reach the material surface they reflect back to the sensor electronics unit. The time-of-flight of the pulses is calculated and directly related to the distance from the point at which the sensor is mounted on the top of the vessel to the material surface (level). The output from the electronics is continuously updated as the level of the material surface changes.
Flexar is available with a choice of two outputs. The standard output is a “smart” RS-485 interface for use with SiloTrack™ PC-based inventory management software or the HMI2 operator interface control console. The second choice is the optional analog output.
