Ultrasonic
Continuous Level Gets “Smart”
Elburn,
IL. —Monitor Technology offers their BulkSonics® smart
transmitters to provide continuous level measurement for
both solids and liquids in storage tanks, bins, silos and
other vessels. The non-contact nature of ultrasonic technology
makes these products ideal for use with powders, granular
materials, corrosives, sticky materials, or other applications
that make contacting level sensors impractical.
BulkSonics® solids
smart transmitters are available in three models for ranges
from 2 to 200 feet. The liquid smart transmitters are available
in four models that cover distances from 0.8 to 82 feet. BulkSonics
smart transmitters for solids applications are equipped with
a joystick to allow easy aiming of the device.
All
BulkSonics® smart transmitters combine state-of-the-art “narrow
beam” transducers with advanced echo suppression software
techniques. This results in unequaled, time-proven reliability.
BulkSonics smart transmitters also offer:
• 4-20 mA, relay and HART Communications protocol output options.
• Local keypad/display module.
• EView-Light PC software (HART option) for remote programming of BulkSonics
transmitters. Monitor also offers an optional EView software package to allow
remote programming of from two to fifteen units.
• Messenger Remote Inventory Monitoring equipment for use with BulkSonics
smart transmitters installed for vendor managed inventory.
BulkSonics® smart
transmitters are backed by Monitor’s industry leading
SecureCareSM customer service and carry a full two-year warranty.

The
Answer is on
ONE Simple-to-Use CD
Elburn,
IL. —Monitor Technology’s unique Interactive
Point Level Product Guide is NOW available on a single CD!
The Interactive Guide is a useful reference tool for anyone
who specifies or buys level instruments for liquid, solids
or slurries. This extensive multi-media Guide assists you
in selecting the most suitable point level device for any
application. There is nothing else like it!
The
Interactive Point Level Guide includes the following:
• “Review My Application” software. Answer questions about
your application by selecting options from on-screen lists. The software uses
your answers to compute and display the point level products best suited to the
process.
• Interactive Product Presentations. The CD contains multi-media presentations
for rotary paddle, RF capacitance, vibrating and mechanical point level sensors.
The presentations are displayed on a viewer that has on screen controls similar
to a VCR or DVD player for simple operation. Each product presentation is broken
into discrete modules for easy viewing. The modules are entitled: “Benefits”, “How
It Works”, “Typical Applications”, “Features”, “Installation
Tips”; and “Key Specifications”.
• Product literature for viewing or printing on all products.
• Information on Monitor’s SecureCare customer service program.
• Monitor Contact Information, a direct link to Monitor’s web site
and “How To Use This Guide” instructions.
Monitor
offers this unique application tool free of charge and believes
it is as important to produce tools that help eliminate the
cost and wasted man-hours associated with misapplications,
as it is to provide durable and reliable instrumentation.

representative.
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,
etc.
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
level indication.
Principle of Operation for the TrueCap RF Capacitance Level
Probe:
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.
