What Is Mettler Toledo Intelligent Sensor Management (ISM)?

Mettler Toledo Process Analytics Intelligent Sensor Management (ISM) is an innovative digital technology for analytical process parameters that combines many features into a unique solution. The foundation of the technology is built from a microprocessor embedded in all ISM sensors. This allows a wealth of valuable features that analog sensors cannot compete with, including a robust digital signal fast error-free measurement, point startup, and advanced diagnostics that clearly inform operators when calibration maintenance or replacement will be required. 

The critical diagnostics tool in ISM is the dynamic lifetime indicator (DLI). The DLI provides technicians with a clear indication of how much the exposure to a process has altered a sensor's condition. In the case of ph sensors by continuously analyzing the process conditions and other factors. The DLI constantly calculates how many days are remaining in the reliable lifetime of the sensor. There is no estimating based on a percentage of remaining life. You receive a precise number of days of life remaining, making it easy to plan maintenance and replacement. If process conditions become more or less harsh, the DLI rapidly responds appropriately. In addition the DLI actually adapts to process conditions to ensure diagnostics are always reliable.

Another important feature of ISM technology is "plug and measure" when connected to an ISM transmitter. The pre-calibrated sensor is instantly recognized and the transmitter configures itself appropriately without any operator intervention. When an exchange of sensor is needed this plug and measure functionality means a pre-calibrated sensor can be installed and be ready to measure in under a minute. This substantially reduces the amount of time that maintenance staff need to spend at measurement points. With its highly informative diagnostics that adapt rapidly to process conditions and its robust digital signal, ISM offers efficiencies in maintenance planning, plant safety and productivity while also reducing production costs.

Continuous, Real-time Measurement for Full Visibility of Total Organic Carbon (TOC) in Pure and Ultra-Pure Water Systems

At-line batch method of monitoring total organic carbon (TOC), which takes measurements at set intervals, is the equivalent of taking snapshots of information. The gaps between measurement intervals could easily miss a critical event, whereas on-line, continuous TOC monitoring done by the Mettler Toledo 6000TOCi total organic carbon analyzer captures any-and-all excursions in real-time.

Monitoring total organic carbon levels is critical to meeting internal water quality specifications and global pharmacopeia regulatory requirements. Missing an increase in TOC levels can put you at risk of contaminating your water system, which in turn could affect production and potentially lead to an out-of-spec event or product recall.

Most TOC analyzers on the market offer at-line batch or non-continuous methods of total organic carbon measurement, which limits TOC data collection to every 6-12 minutes. But much can happen in six minutes.  When you are subject to an audit or have a quality problem, how are you sure that you did not experience a problematic TOC excursion between batch samples?

The 6000TOCi analyzer’s true continuous measurement along with its comprehensive record keeping and advanced diagnostics provide audit-ready TOC compliance and complete control of your water system.

Validating Water Cycle pH Requirements Using Conductivity and Calculated pH

In thermal power plants, pH measurement and control in the water steam cycle are critical to minimizing corrosion. Cycle chemistry guidelines specifically target narrow pH ranges.

However, in high purity water and steam, there are not enough ions in the water to generate a pH response, causing the pH reading to be unstable. Fortunately, conductivity has a direct relationship with pH when the sample contains only pure water with the typical alkaline treatments, such as ammonia and amines. In fact, cycle chemistry in many plants relies primarily on the related specific conductivity values. However, correction for minor contaminants by measuring the cation conductivity of the sample is needed to provide accurate results. The specific and the cation conductivity values are used in an industry accepted calculation that provides the highest accurate conversion to pH. Under normal operating conditions, this calculation provides more accurate and reliable results than pH electrodes can provide, for two reasons:

1. Conductivity is linear, with concentration which provides much higher resolution than pH sensors all of which give nonlinear response to concentration.
2. Conductivity sensors can be directly calibrated with minimal introduction of error. 

All pH reference electrodes have a variable junction or diaphragm potential that can change between buffer calibration and process measurement, introducing some uncertainty to subsequent measurements.

This makes calculated pH based on conductivity significantly more accurate. However, with major contamination, such as when a condensate exchange polisher's resin is exhausted, and an acid leak occurs, the pH would drop below 7, which is outside the ideal range for using calculated pH and would generate errors. Thus, to avoid contamination, it is recommended that both traditional pH measurement, and calculated pH based on conductivity, be used for optimal pH control.

METTLER TOLEDO Thornton's M800 multi-parameter transmitter can provide traditional pH measurement, calculated pH, as well as specific and cation conductivity to ensure accurate and reliable pH control. The M800 even has a built-in alarm to alert you if the pH measurement deviates from the calculated pH measurement for extra security and peace of mind.
