Solids Flow Monitors Improve Process Performance

The Model SFI and SFD-2 line of solids flow detectors 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.

Solids Flow Monitors like the Model SFI and SFD-2 can be used in a wide variety of applications. 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 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. These two applications illustrate the potential for use in improving your process efficiency and maintaining process safety.

The Model SFI and SFD-2 solids flow monitors are brought to you by Monitor Technologies LLC. Monitor Technologies has pioneered level measurement for powders and bulk solids for five decades. The experience and market knowledge gained has earned Monitor a reputation for providing high quality and reliable product solutions.

SafePoint^®
"True" Fail-Safe Level Switch

The SafePoint rotary paddle level switch with a self-validating design detects material presence plus continuously monitors its own ability to function. The analysis includes sensor health and system power failure, which makes the SafePoint truly “fail-safe”. The SafePoint incorporates patented use of Hall-Effect technology, dual outputs to indicate both material presence and unit health, and microcontroller technology to continuously protect bulk solids processing and storage from the consequences of unknown sensor failure by providing immediate indication of a sensor failure and confirmation of proper operation.

Other practical features of the SafePoint include rugged construction, motor shut-off when paddle becomes impeded to maximize motor life, twist On/Off cover for bolt free removal, and local status indicating light (except hazardous location models)

A practical application for the SafePoint would be to use this "true" fail-safe product if undetected sensor failure could result in a catastrophic process problem.
