Microwave Non-Contact/Non-Invasive
Solids Flow Detector Indicates Material Flow Problems
Elburn, IL -- The Model SFD-2 and
SFI solids flow detectors use microwave technology
to detect the flow and no-flow condition of powders
and bulk solids as they discharge from bins and silos. The
SFD-2 and SFI can be used in in chutes, pipes and other
conduits that these materials may flow through. The
sensor transmits microwave energy into a flow conduit
and detects the material flow as the energy is reflected
off the material. The transceiver detects a Doppler
shift in the microwave indicate material movement or
flow.
Both units are easily installed and setup. The use of microwave technology
means that the transceiver can be mounted so that it is non-invasive into the
flow stream and even non-contact if mounted on the outside of a non-metallic
window or pipe/chute. The Model SFD-2 provides relay contact closures in
response to change sin flow and no-flow conditions. The Model SFI provides
an analog output. When the SFD/SFI output is monitored, material stoppage
(flow to no-flow) can be detected and flow-aid devices, such as aerators, vibrators
or air cannons, can be initiated.

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.
