Selection of
Point Level Measurement Technology Made Easy

Elburn, IL. — Never before has finding the right point level instrument for solids, liquids or slurries been so easy.

Monitor Technologies Point Level Interactive Product Guide is a useful reference tool not to be missed. This six CD multi-media guide assists you in selecting the most suitable point level instrument for a specific application, and avoid the cost and wasted man hours associated with misapplication.

The first CD features a unique question and answer software program that allows users to describe a specific level measurement application. This software uses your answers to compute and display the point level product(s) suited for your specific application need. The user is then directed to the applicable product guide for further examination of the technology selected.

The interactive product guides, CD2-CD5, are devoted to Rotary Paddle, RF Capacitance, Vibratory and Mechanical point level instruments. To learn more about a product simply insert the appropriate CD and you will be able to view information such as how the device works, typical applications, features, installation tips, and key specifications. All interactive product guides contain product literature, contact information, and a link to the Monitor website.

All the information contained on the first 5 CDs will be condensed and included on the final sixth CD. CD6 will include new features, such as the ability to create a product code and email a “Request For Quotation” to Monitor.

The Interactive Product Guide is a part of Monitor’s SecureCareSM customer service. SecureCare is unequaled education, service, and support that provide durable instrumentation having the lowest total cost of ownership. Each interactive product guide contains a presentation on SecureCare and the philosophy behind our excellent customer service.

You can obtain your free copy of the Point Level Interactive Product Guide by contacting Monitor directly, or contacting any local Monitor sales representative. Initial shipments will include a jewel case of four CDs for convenient storage. User registration in required to ensure delivery of CD5 and CD6.

Model SFD-2
Reliable Continuous Level Monitoring

Elburn, IL. — Monitor’s Flo-Pad bin aerator promotes the flow of any dry bulk powder or granular material from bins, hoppers and silos. Such materials are highly aerated when entering the storage vessels, and flow quite easily entering the vessel by pneumatic or gravity feed. After being in storage for a time, the air escapes and allows the material to pack, and behave more like a solid mass than a fluid mixture. Flo-Pad uses multiple Evassers mounted on a single air plenum chamber to create multi-directional air release and re-fluidize stored material.

Flo-Pad is virtually maintenance free and does not create noise or damaging vibration, like pneumatic or electric actuated vibrating devices. The Evassers have a standard neoprene boot that is designed to prevent material backflow. In addition, the Evassers are less likely to become clogged due to moisture, as are aerators that use cotton or canvas to diffuse the air.

Flo-Pads can be used for virtually any application. They are available in 18 in. (457 mm) and 60 in. (1524 mm) sizes, having 8 and 28 Evassers respectively. The most effective aeration of dry bulk materials is typically achieved by use of multiple rows of Flo-Pads, one row located in each quadrant of the sloping vessel bottom. Flo-Pad maintains a constant 2 to 5 psi (0.14 to 0.35 bar) supply of air. Units are also available for higher pressures of up to 80 psi (5.5 bar), to dislodge and move highly settled materials, and for high temperature applications.

Spotlight: RF Capacitance Level Sensor

TrueCap® MK-2
Advanced RF Capacitance Level Probe

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.
