Free Solids Flow Indicator
IL - Using microwave technology,
Monitor's Solids Flow Indicator (SFI) detects flow in solid
material applications including gravity chutes and pneumatic
pipelines. The SFI features an analog output relative to
the magnitude of flow. This provides more information for
the user than a on-off flow detector.
design provides long-term reliability and elimination of process
contamination. Intrusive probes might wear out, break off or
inhibit material flow. The non-contact/non-intrusive design
is just one of the many reasons that the SFI is maintenance
The SFI is
equipped with a rugged housing that is rated for Class II dust-ignition
proof environments and meets NEMA 4 water-tight and dust-tight
include a built-in averaging adjustment for application customization
and LED indicators for visual indication of material activity
and verification of operation. The SFI also has an excellent
The TrueCap® Model MK-2
RF Capacitance point level probe is designed to provide a superior
and stable sensitivity threshold making it suitable for a variety
of powder / bulk solids and some liquid or slurry applications.
Advanced features of the Model MK-2 include: > Automatic immunity to material build-up on
the probe by its driven shield design > Push-button calibration > Enhanced temperature compensation > Maximized reliability via smart sensing algorithms
like “self-validating” fail-safe protection > Visible status LED on ordinary location units > Versatility through a variety of configuration
options including: hazardous location version, split architecture
design, quick-connect process connection, stub probe, cable extensions,
solid extensions, Nylon® probes, Ryton® - equiv. probes,
A practical application for the TrueCap would be to use this level sensor where
a residual material build-up on a different sensor would cause a false material
Principle of Operation for the TrueCap RF Capacitance Level
The vessel wall and the active probe element establish an impedance reference
between each other when exposed to air which has a dielectric constant of 1.
When materials with a dielectric constant greater than 1 are in close proximity
to the probe, the impedance of the sensing field between the sensor and the vessel
wall will change. Once the amount of change exceeds a threshold that was electronically
determined during the calibration process, an output relay will either be energized
or de-energized depending upon the position of the fail-safe selector on the
probe’s electronic circuit board. A change of as little as .5 pico-farad
is all that is necessary for the probe to sense the presence of material.
