Rosemount Analytical Model WQS also performed unattended with no maintenance required during 52 day deployment, demonstrating lowest overall cost of ownership
IRVINE, Calif., June 12, 2006 - Emerson Process Management has announced that during the recent verification of the Rosemount Analytical Model WQS water quality monitoring system by the U.S. Environmental Protection Agency (EPA) Environmental Testing Verification (ETV) program, the Emerson system achieved the highest overall system accuracy of 94 percent, while the next nearest competitor scored an average of 85 percent with others as low as 51 percent. Significantly, this score was achieved while the Emerson system required and received no scheduled operator maintenance unlike other tested systems that were regularly maintained.
According to Richard Baril, director of homeland security products for Emerson Process Management, "The results of the EPA test were gratifying in that they demonstrated the fitness of the WQS for the critical real-world water quality applications in which it's used, as well as its lowest overall cost of ownership."
The Rosemount Analytical Model WQS multiparameter system was evaluated along with four other water monitors. The testing was conducted by Battelle in the advanced monitoring systems center. The testing consisted of three stages. Stage I assessed the accuracy of the measurements during nine, four-hour periods against laboratory grab samples, and the WQS achieved 84 percent system accuracy, while the next nearest competitor rated 68 percent systems accuracy. Stage II reviewed response to changes in water quality by injecting contaminants (nicotine, arsenic trioxide and aldicarb) into the pipe loop. The Model WQS rated at 94 percent system accuracy during 52 days of continuous operation and the nearest competitor ranked 78 percent system accuracy. Stage III consisted of duplicate injections of aldicarb and E. coli. The overall system accuracy score for the Model WQS was 94 percent, while the other devices ranged from 51 percent to 85 percent. According to Dr. Ryan James, ETV verification test coordinator, Battelle, "The report describing its performance during the test is now available on the ETV website: epa.gov/etv/centers/center1.html."
In addition to its accuracy, The Model WQS requires no expensive reagents for operation and demands the lowest levels of scheduled maintenance making it the most cost-effective system available on the market.
The Model WQS multiparameter water quality monitoring system comes as a complete "plug and plumb" panel system designed to withstand the rigors of a real-world distribution environment. Not only are the sensors field-proven for long life and low maintenance requirements, but the system requires no reagents, providing the lowest cost of ownership for any solution available in the industry. The Water Quality System enables plants to establish a baseline for critical measurements including turbidity, conductivity, pH, ORP, free chlorine, monochloramine, dissolved oxygen, ozone and temperature, so that when changes in these measurements are detected, plants are alerted of an event so they can respond accordingly.
The Rosemount Analytical liquid measurement technology is a key component of Emerson's PlantWeb® digital plant architecture that delivers operating efficiency improvement.
