Water Quality Monitoring: Emerson Introduces Turbidity Measurement In Model 1056 Instrument

Single- or Dual-Input Instrument Simplifies Operation and Maintenance and Reduces Total Cost of Ownership for Turbidity Analysis in Potable Water Plants

Irvine, CA - Emerson Process Management announced that the Rosemount Analytical Model 1056 instrument, featuring enhancements, reduced maintenance requirements and advanced diagnostics, is now available with turbidity measurement making it the optimum choice for potable water plants. The Model 1056 is the new intelligent line-powered analyzer for the Rosemount Analytical Clarity II Turbidimeter, which also includes an optical turbidity sensor and debubbler assembly.

The new Model 1056 turbidity analyzer is now available with two new power supply options – universal AC-driven and 24VDC. The AC-driven power supply supports 85-265VAC 50/60Hz line conditions and provides auto-switching capabilities for use both in the U.S. and Europe. The new AC switching power supply and the 24VDC power supply include alarm relays with programmable timers to allow alarms to be triggered when programmed thresholds are reached or process events occur.

The Model 1056 is designed to significantly simplify operation and maintenance making it ideal in water plants where tight budgets often increase workloads on personnel. It is offered as a single- or dual-input analyzer that reduces the cost per loop and saves space by offering an unrestricted choice of measurements, including turbidity, pH/ORP/ISE, conductivity, oxygen, chlorine, ozone and many other combinations. It is easy to use and features the largest high-contrast LCD display available on a line-operated instrument, making the display exceptionally easy to read even from a distance. The instrument also offers; intuitive menu screens; and seven programmed languages, including the new addition of Chinese language user menus. Four process variables, or diagnostic parameters, are displayed simultaneously from every screen, giving operators useful process information at a glance. The placement of variables on the screen is easily customized based on the user's requirements. When changing screens, the simple, intuitive, plain-English menus and help-screens make operation easy without need for manuals or instructions. No more than three button pushes are required for any operation. In addition, the modular design of the instrument allows signal input boards to be field-replaced making configuration changes easy.

Featuring advanced embedded advanced diagnostics, the Model 1056 analyzer continuously monitors itself and the sensor(s) for problematic conditions and alerts operators to problems that may occur. A push of the diagnostics button reveals PlantWeb alert troubleshooting and maintenance messages and help screens guide the user in troubleshooting.

"The addition of turbidity analysis to our Model 1056 product line is significant and enables Emerson to continue to be the single-source provider of the most advanced and easy-to-use analysis technologies for potable water plants, as well as a broad range of industrial processing applications," said John Wright, vice president of marketing, Rosemount Analytical Liquid Division of Emerson Process Management. "We built the new 1056 instrument based on the real-world demands of plant operators for ease of use, reduced maintenance and improved total cost of ownership in today's environment of declining budgets, staffing and resources."

The Emerson Model 1056 turbidity analyzer can be ordered starting in July 2007.
