Flexar® Guided Wave Radar Instrumental at New Ethanol Facility
The latest generation of an Ethanol producing plant is just about to go on-line in Wisconsin. The news story and video can be found at the link here. In addition, Monitor’s Flexar® guided wave radar level sensors are instrumental at this facility and used to measure changing levels of corn in various conditions. A total of seventeen Flexar sensors are installed. The benefit of guided wave radar is its continuous measurement capability, moderate cost, ease of installation and start-up. Guided wave radar technology is used in a wide variety of applications in many different industries. Its universal appeal is another reason for the fact that it is growing in popularity and use by some 21% per year (according to a recent market study).
Guided wave radar continuous level measurement sensors operate using TDR technology. TDR, or time domain reflectometry, has been in use measuring process levels since the early 1990's and is well proven in all types of liquid and bulk solids applications. The sensor electronics initiates microwave (radar) energy pulses continuously and these are focused and sent down a wave-guide (probe). The wave-guide is used to guide the energy to the material surface. This is advantageous and superior to open-air devices as you can imagine. The energy pulses reflect off the material surface and the time-of-flight is measured and related directly to the distance from the sensor to the material surface. Flexar level sensors are proven very reliable and accurate.
Flexar guided wave radar units work in a wide range of applications like corn in multiple Ethanol plant applications, plastic pellets, PVC resin and compound, calcium carbonate, clays, sand, cement, flyash and even seed. Monitor Technologies has been providing innovation level monitoring and measurement solutions for bulk solids and liquids for five decades.

Why Use Solids Flow Monitors?
Assist in detecting problems & increasing automation
From complex automated systems with pneumatic lines
to straight-forward gravity chutes, solids flow monitors can help
to improve process performance. They are effective in detecting flow
problems, as well as enhancing the level of automation at a facility.
Solids flow monitors can assist in detecting problems in flow caused
by equipment failures, plugged lines, leaks, material bridges upstream,
low or no material, etc. They can also be used to add automation
to a process like opening or closing valves, turning a conveyor on
or off, and initiating a process function (spraying of a product
additive).
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 and extremely reliable and rugged to
withstand the rigors of the installation and your process extremes.
Since there are no moving parts, these monitors can provide dependable,
low-maintenance service for many years.
Solids flow detectors like the Model SFI and SFD-2 can be used
in applications for a
variety of industries including construction materials (cement, sand,
gypsum, etc.), wood chips / sawdust, feed mills & grain processing,
consumer foods (cereal, coffee, sugar, cocoa, powdered milk, barley),
plastics, chemicals & pesticides, pharmaceuticals, and more.
One customer uses the analog signal from a Model SFI unit to monitor
the flow of carbon black in toner cartridge manufacturing to ensure
positive flow before further processing and to detect no-flow and
possible plugged conditions. Another company uses the Model SFD-2
solids flow detector to monitor the flow of coal into the burner
of a coal-fired power plant to detect no-flow conditions and ensure
safety.
Whether a solids flow monitor is used to detect problems, increase
automation or both,
the end result is a substantial long term cost
savings through: eliminating product waste,
cutting “downtime”, reducing employee time spent on watching
the processes or cleaning up spills/messes, increasing product quality
(reducing defective product), and decreasing maintenance time / replacement
costs on other methods of flow detection.
