Advanced Sensors for Power Plant Instruments

Mettler Toledo is offering pH and other instruments with advanced digital sensors that go well beyond basic measurement and digital signal conversion within the sensor. Such sensors fully exploit the opportunities available when measurements are made right next to the sensor element. They don’t compromise the measuring circuit design in order to accommodate the resistance and capacitance of long analog signal cables, especially for conductivity measurement. They don’t incur uncertainty when different measuring circuits are used to calibrate the sensor than are used in the final installation because the measuring circuit is inseparable from the sensor elements. In addition, they always utilize correct calibration data for their measurements because on-board memory retains it. Advanced digital sensors include real-time predictive diagnostics. These take the sensor’s cumulative operating exposure into account to forecast in real time when calibration, maintenance and replacement will be needed. Taken together, the sum of these advanced sensor capabilities are designated Intelligent Sensor Management or ISM®. ISM sensors are able to warn of the need for service before loss of accuracy or failure, making the measurements more reliable and increasing the efficiency of maintenance scheduling. They can also eliminate unnecessary servicing

Combined cycle On-Line Measurements - Mettler Toledo presentation by David Gray

Specific conductivity, cation conductivity, dissolved oxygen, redox, pH, sodium, silica and total organic carbon are all measured by MT instruments. Intelligent digital sensors have advantages. Optical DO offers faster measurement and less maintenance but polarographic offers measurement to lowest concentrations

New Approach to On-Line Sodium Measurement, presented by David Gray, Mettler-Toledo Thornton Inc., at Electric Utility Chemistry Workshop, June 7-9, 2011, Champaign, Illinois

A New Approach to On-line Sodium Measurement David Gray, Mettler-Toledo Thornton, Inc. Sodium has been a critical measurement parameter for ensuring water treatment performance and purity for nearly four decades. Monitoring cation exchange performance and the purity of makeup water, steam and condensate has benefitted from measurement of this key parameter. Many refinements have been made to the ion-selective electrode method for on-line sodium measurement for these applications. Described here are yet further improvements to this technology including an unique integrated electrode system that measures both sodium and pH to assure proper reagent delivery. The system design minimizes reagent consumption and reduces maintenance requirements well below current practice. The new sodium system uses a particularly simple automatic calibration method and also provides the ability to measure grab samples easily. Its implementation with an operator interface common to other parameters including conductivity, dissolved oxygen, pH and ORP makes it especially convenient for installation and operator training.

Electric Utility Chemistry Workshop, June 7-9, 2011, Champaign, IL, Exhibitors

Now in its 31st year, this comprehensive program features state-of-the-art information on controlling corrosion, improving operation efficiency, and meeting environmental challenges in fossil- and nuclear-fueled power plants. This year’s program is geared toward improved training and continuing education of personnel responsible for electric utility cycle and environmental chemistry. More than 3,000 chemists, consultants, and power plant administrators have attended the workshop since its inception in 1981. The 2011 program has been developed by a committee of representatives from midwestern electric utilities, the Illinois State Water Survey, the University of Illinois at Urbana-Champaign, and consultants serving the power industry. Some of the most popular features of the workshop are the Utility Experience presentations. Seasoned professionals from utility companies discuss their experiences on a range of topics. The entire workshop has been structured to encourage participation from attendees.
