The 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 is also suitable for use with a multiplicity of liquids. It is used in a wide assortment of vessels and industries for measuring levels up to 200 ft (61 m) in height.
Bringing the Pieces Together: Manufactured at our facility in Elburn, IL, we uniquely combine this proven and strategically-acquired technology with almost five decades of expertise and focus in powder and bulk solids applications, and with our SiloTrack™ inventory management software interface. Monitor Technologies uniquely provides the best solutions in level measurement and inventory management of powders and bulk solids.
The Flexar™ guided, wave radar level sensor and/or transmitter requires no field calibration or re-calibration and can be set up easily by customer personnel without the use of special tools or training. Flexar™ units are suited for almost any application, can operate with process temperatures up to 392º F (200ºC), can be provided with a variety of process connections and work reliably with materials having a wide range of bulk densities and dielectric constants.
Flexar™ is available with a choice of two outputs. The standard output is a "smart" interface for use with SiloTrack™ Version 3.5 PC-based inventory management software. This network-ready software provides a flexible graphical interface for up to 128 "smart" output sensors. In lieu of this "smart" output, an optional analog output is also available.

Principle of Operation
N/A
Flexar® smart guided wave radar level sensors and transmitters operate using TDR (time domain reflectometry) principles that were first developed in the middle part of the 20th century for use in the geological field. Further development of TDR led to its use in the telecommunication industry for detecting breaks in cables. Flexar technology was pioneered in the mid-late 1990’s when TDR was applied to level measuring applications within the process measurement industry. |
Applications
N/A
The Flexar® smart guided wave radar continuous level measuring system can be used in a wide variety of applications, including powders, coarse/fine granular solids, liquids, foodstuffs and even some corrosive substances. Flexar sensor technology is proven in many difficult applications including those where dust levels make it difficult for other technologies to perform reliably, especially at long ranges. |
Remote Inventory Monitoring
N/A If material levels need to be monitored at one or many locations (i.e. your facility, a location down the street, or a plant on the other side of the world) the Flexar system can provide continuous, reliable and accurate measurements. Using SiloTrack™ Version 3.5 software, inventory monitoring from remote locations has never been easier. |
