June 2009: FLEXAR^®

FLEXAR^®Guided Wave Radar Offered in a Split Architecture Version For More Extreme Environments

Flexar^® guided wave radar (GWR) sensor is a continuous level measurement system using TDR (time domain reflectometry) principles where radar pulses are focused down to the material surface by the unit's wave guide (a heavy duty cable) and the time-of-flight of the pulse reflection back to the instrument electronics is directly related to the empty distance in the vessel and the material level. Guided wave radar technology has proven successful and an excellent choice for most powder and bulk solids applications as well as a multitude of liquids applications. With the optional split architecture design, the electronics are separated from the sensor so that Flexar can be used in more extreme environmental conditions where elevated temperatures or excessive vibration might be involved.

Other benefits of Flexar^® include no moving parts for less wear and tear; the employed technology allows the sensor / transmitter to be virtually unaffected by and reliable in dusty conditions; no field calibration is required to provide easy installation; and setup and a universal power supply for high or low voltage options. The Flexar sensor can also be supplied with a choice of outputs. The analog 4-20mA output version can be interfaced to your existing PLC or DCS and the “Smart” RS-485 output version is compatible with the PC-based SiloTrackTM Inventory Management Software. The SiloTrack software automates level monitoring and report generation, sends email notifications to suppliers or corporate locations and allows remote viewing of material level inventory.  Please visit www.flexar.info for more details.

Solids Flow Detection

Microwave solids flow detectors can be used in a variety of applications including feed mills & grain processing, consumer foods (cereal, sugar, cocoa, coffee), chemicals & pesticides and more. For example, one company uses Monitor’s Model SFD-2 solids flow detector to verify the flow of feed pellets through their various transport lines which involves a process where a horizontal screw auger is conveying pellets over to a vertical gravity chute.  The chute then directs the pellets to a process down below. They have carefully placed the SFD-2 so that it detects the pellets as they fall directly across the sensor face. (See Below)

The Model SFI and SFD-2 line of solids flow detectors from Monitor Technologies, LLC provide analog or relay outputs to indicate the flow / no-flow condition of powder and bulk solids materials in chutes and pneumatic conveying lines.  Using microwave Doppler radar technology these units are non-invasive plus extremely reliable and rugged to withstand the rigors of the installation and your process extremes. From automated systems with pneumatic lines to gravity chutes, solids flow monitors can help to improve process performance. They can assist in detecting flow problems, as well as, enhance the level of automation at a facility like turning a conveyor on or off.
