Enhanced Level Measurement Technology to Meet the Tough Demands of Bulk Solids Applications

Emerson Process Management has introduced a number of new function and certifications to its enhanced level measurement devices in an effort to address the challenges present in accurately measuring level and volume of bulk solids and powders in large vessels, bins and silos.

The new features will help to minimize maintenance, enable easy integration and expand the range of suitable applications.



The Solution to Measurement Challenges

"Uneven surfaces, irregular build-up and harsh, dusty and potentially explosive environments make measuring the level of solids in large vessels problematic, impacting inventory control decisions," said Asael Sharabi, technical director at Emerson Process Management. "Emerson's enhanced Rosemount instrumentation meets these challenges to provide users with greater control of inventories and entire manufacturing processes, with significant financial benefits."



The Rosemount 5708 Series 3D Solids Scanner uses acoustic measurement and 3D mapping technology to provide extremely accurate continuous level and volume measurement in order to support manufacturers' need for better inventory control. The device is now also suitable for a wider range of applications. It is now ATEX/IECEx certified for installation in areas with potentially explosive atmospheres, something that is found often in solids measurement applications. A new mounting adaptor also allows the device to be installed within electrostatic precipitator (ESP) hoppers. By using its 3D visualization capability to map out the surface of the fly ash that builds up in the hopper, operators can optimize the process, reducing cost, risk and wear and tear.


Seamless Integration and Service

In order to combat any difficulties that may come up during installation and integration, Emerson has introduced full SCADA integration support for the solids scanner. Users can now seamlessly integrate 3D visualization of the surface level into Emerson's OvationTM or DeltaVTM distributed control systems, delivered directly to control room operators. The installation process couldn't be easier!

And for those areas where there is no existing cable infrastructure, wireless is the key to a successful project. Both the solids scanner and the Rosemount 5402 Non-contacting Radar, which provides bulk solids level measurement for applications with smaller sized vessels, can now be connected to a WirelessHART network using a Smart Wireless THUMTM Adapter. This enables easy integration to the automation architecture, reducing installation cost and time.

Low Maintenance to No Maintenance

The new functions introduced in the solids scanners were designed to reduce and even eliminate the need for maintenance. The new air purging connection for the Rosemount 5402 prevents clogging of the antenna in applications with very dusty environments. The existing self-cleaning function on the Rosemount 5708 can now also be complemented with a new PTFE coated antenna which helps extend maintenance intervals even further, especially where very sticky materials are present.
