Emerson Continues to Enhance Level Measurement Technology

In it's quest to further provide solutions to the challenges of accurately measuring level and volume of bulk solids and powders in large vessels, bins and silos, Emerson Process Management has enhanced its range of level measurement devices. Their new functions and features will help minimize maintenance, enable easy integration and expand the range of suitable applications.

The Enhanced Rosemount Instrumentation

"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 Solid Scanner uses acoustic measurement and 3D mapping technology to provide extremely accurate continuous level and volume measurement now suitable for a broader range of applications. This directly supports manufacturers' need for improved inventory control.

Installation Solutions

The Rosemount Solid Scanner is now ATEX/IECEx certified for installation in areas with potentially explosive atmospheres, often found 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 on the hopper.

Additionally, 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. At locations without existing cable infrastructure, wireless is the answer. Both the solids scanner and the Rosemount 5402 Non-contacting Radar 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.

New Functions

The new functions introduced were designed to eliminate device maintenance requirements as much as possible. The new air purging connection for the Rosemount 5402 prevents clogging of the antenna in applications with very dusty environments. The already present self-cleaning function on the Rosemount 5708 can now be complemented with a new PTFE coated antenna which helps extend maintenance intervals even further, especially where extremely sticky materials are present.
