Guided wave radar level sensor

The Flexar is a continuous level measurement sensor used for monitoring the amount of material within tanks, silos, bins and many other types of vessels. It is used to measure the level of powders, granular and liquid materials and is a universal technology for use in a wide range of applications and industries. It is capable of operating in environments with process conditions up to 200°C with pressures from -1 bar to +40 bar.

Using guided wave radar TDR (time domain reflectometry) technology, the Flexar continuous level sensor measures the distance to the material surface, or level of the material, and can be utilised in applications to calculate volume. Internal operating conditions are continuously monitored and any sensor failure or trouble is indicated by the fail-safe output condition selected by the user.

The Flexar can measure liquids typically up to 60 m in height and solids up to 30 m. The continuous level measurement sensor is especially suitable for measuring the level of fine powder materials like flour, cement, fly ash and many other materials. Flexar is unaffected by airborne dust like ultrasonic and other technologies are. Flexar technology is uniquely able to reliably measure changing material levels of dusty materials, even during pneumatic filling. No field calibration is required and the unit is easy to install and set up. Output options include 4-20 mA analog (with HART) or RS485 digital communications for use with Monitor’s inventory management software.
