Level Sensor works where other sensors fail.
August 13, 2002 - Phase Tracker® uses an electromagnetic field that senses mass of material in 6 in. diameter area around sensor. It is not affected by signals reflecting off tank sidewalls, cannot be blinded by dust, and can reliably measure product when cross members and irregular structures are present. It works in dust, foam, non-air vapor, fumes, changing and low dielectric constants, abrasives and corrosives, corrugated bins, and tall, narrow silos.

Phase Tracker® Works Where Other Level Instruments Fail
SPARTANBURG, SC, August 2002—While it is often compared to ultrasonic and micro-power impulse radar (MIR), Bindicator's Phase Tracker continuous level sensor differs dramatically because it uses a unique principle of measurement that cannot be duplicated by other technologies. Phase Tracker overcomes common sources of unreliable measurement in silos because it is not affected by signals reflecting off tank sidewalls and cannot be "blinded" by dust as is typical of ultrasonic technologies. Phase Tracker can reliably measure product when cross members and irregular structures interfere with through-air radar and ultrasonic measurement. Unlike radar technologies, Phase Tracker has an inherent immunity to product coating on the sensor. An electromagnetic field senses the mass of material around the sensor, approximately 6" in diameter. Coatings normally do not occupy the entire 6" space and thus are transparent to the signal. In marked contrast to ultrasound, which can be "blinded" by the fill stream, Phase Tracker allows continuous control over the important fill cycle even with pneumatic loading. Phase Tracker has proven to outperform competing technologies in dust, foam, non-air vapor, fumes, changing and low dielectric constants, abrasives and corrosives, corrugated bins and tall, narrow silos.
