9 Measurement Systems The Perfect System for Your Loop System Selection How to Build a Measurement System Select Your Components For proper operation and optimal performance in your process, each element of your measurement system must be carefully chosen. A complete measurement system requires components including a sensor, housing, process connection, cable and transmitter. 1. Sensor selection METTLER TOLEDO sensors are high performance and long lasting. However, the proper selection should be made according to the application and process environment to which it will be exposed. Basic selection considerations are: Measurement range Operating temperature range Pressure resistance Length Accuracy Cable plug Built-in temperature compensation Hygienic requirements 2. Transmitter selection Transmitters are the component which communicate to the user and translate a sensor s readings into displayed measurements. The transmitter also transfers the data to the process control system. A variety of transmitters are available to suit each application and functional requirement. Basic selection considerations are: Available functionalities e.g. PID control, number of inputs and outputs, data logging etc. Power supply Process environment with waterproof rating and agency certifications Customer conveniences, such as backlit display, multi languages, password protection Area classification 3. Housing selection Housings hold the sensor while providing contact with the process medium. Basic selection considerations are: Sensor compatibility Housing design: Stationary for sensor protection; retractable for safely withdrawing the sensor without process shutdown Immersion depth into the medium Process connection style Appropriate material of construction for process compatibility 8 METTLER TOLEDO US and Canada

10 4. Process connection selection Our process connections fix the housing to the vessel, reactor, pipe or open basin. Basic selection considerations are: Straight or inclined type Sockets, flanges and appropriate thread Appropriate material 6. Other components Handling and maintenance may also be enhanced by adding useful accessories such as sensor simulators or polarization units. 5. Cable (if needed) Various lengths of cable can be selected to provide flexibility in locating the sensor. METTLER TOLEDO US and Canada 9

11 ISM Into the Future of Process Analytics ISM Intelligent Sensor Management Intelligent Sensor Management Intelligence Starts in the Head ISM, a breakthrough technology from METTLER TOLEDO, allows users of process analytical equipment to significantly reduce the maintenance costs of loops, while increasing the safety of the production process. Fast, error-free installation Operation errors at the transmitter are largely excluded, since all relevant status and configuration information is automatically transferred from the sensor to the transmitter during start-up. Sensors are immediately recognized during installation Operational availability of a measuring point is assured within seconds ISM-enabled measuring systems recognize manufacturer, sensor type, serial number, order number and last sensor calibration Calibration history is available for trend analysis Convenient, accurate sensor calibration away from the process Quick and easy replacement of sensors directly at the measurement point, using pre-calibrated units. The sensor can be replaced and is operational within seconds, saving time and increasing operational availability Reduced maintenance costs, greater process reliability On-line diagnostics information allows you to schedule sensor maintenance or replacement and to optimize operating efficiency while reducing maintenance costs. This in turn provides improved process reliability and avoids unscheduled process downtimes. Measurement and diagnostics data are continuously monitored Predictive diagnostics information with the Dynamic Lifetime Indicator (DLI) for ph, DO, and Ozone sensors Operating hours are recorded for each individual sensor The Adaptive Calibration Timer (ACT) monitors the calibration interval according to sensor wear The DLI estimates in real time the remaining lifetime of the electrode 10 METTLER TOLEDO US and Canada

12 The ISM solution Specific to the new line of ph and oxygen ISM sensors is that signal processing is integrated in the sensor head itself. Fully digital communication to the transmitter delivers low impedance signal transmission with a digital IEEE compliant communication protocol. This ensures undisturbed data exchange which is insensitive to spurious interferences, leading to greater process reliability. ph, oxygen, and ozone ISM sensors work with the M300 and M800 transmitter lines.

13 Introduction Control Your Process Regardless of Your Application Conductivity / Resistivity Inner electrode rod Conductivity / Resistivity Systems When Optimal Performance Is Essential Electrolytic conductivity is a widely used analytical parameter for water purity analysis, monitoring of reverse osmosis, cleaning procedures, control of chemical processes, and in industrial wastewater. Commonly used techniques Electrolytic conductivity is a measure of the total ionic content of a solution. Two main methodologies to measure conductivity are: 2-electrode sensors are for measurements in high purity water and relatively low conductivity ranges 4-electrode sensors are for mid to high ranges. They are more resistant to fouling than two-electrode designs METTLER TOLEDO offers both methodologies. Outer electrode cylinder Fig. 1: Concentric 2-electrode design 2-electrode sensor design (Fig.1) An AC voltage is applied across the 2 electrodes, and the resistance between them is measured. The built-in temperature sensor provides fast accurate measurement. The cell geometry and the high solution resistance allow for very accurate and precise conductivity determination. Sensors are used for water conditioning and purification stages where they are capable of detecting minute levels of impurities in ultrapure water. 4-electrode sensor design (Fig.2) An AC voltage is applied across the 2 outside electrodes. The principle is to measure the voltage drop across the 2 inner electrodes. Therefore, polarization errors are eliminated. Since this technique measures potential drop, the measurement remains accurate. It permits easier in-line cleaning and it can be installed in smaller piping than inductive sensors. UniCond Conductivity/Restivity Sensors with ISM (Fig.3) The UniCond conductivity/resistivity sensor advancement integrates the measuring circuit and the physical sensor into a single unit. UniCond conductivity/resistivity sensors provide exceptionally wide measurement ranges due to their advanced built-in measuring circuit. The on-board measuring circuit eliminates interference from lead wire resistance and capacitance. Only digital signals go back to the transmitter. The UniCond design mitigates the effects of polarization enabling the upper range of the conductivity sensor to be greatly expanded. UniCond sensors provide the ability to accurately measure from ultrapure water to brackish water (up to 50,000 µs / cm) with a single integrated sensor, greatly simplifying water treatment instrumentation. AC voltage source These sensors are used for concentration measurement of acids, alkalis, and salt process streams.

25 Pure Light Simple Water Quality Indication Water Quality 656 Pure Light Water Quality Indicator with Timer The Pure Light is a go/no-go indicator for the quality of pure water from purification systems including service deionization, reverse osmosis, and distillation. Under normal conditions, the green light is illuminated, indicating that the water is in the acceptable purity range. When the purity falls below the user selected set point, the indicator light switches from green to red. The user can activate the time function to also alarm based on time and prevent organic or biological fouling of the system. This easy to interpret, go/no-go, signal alerts the user to take appropriate action. Features/Benefits: - Low voltage operation - the indicator operates on 6 VAC. - Five ranges, user-selectable - jumper permits the user to select the acceptable purity level threshold to meet the application. Threshold limit can be re-set as needed to one of the following five settings. Restivity Conductivity 50 kω-cm 20 μs/cm 200 kω-cm 5 μs/cm 500 kω-cm 2 μs/cm 1 MΩ-cm 1 μs/cm 2 MΩ-cm 0.05 MΩ-cm - BioFouling timer - includes selectable timer that indicates the elapse of 90 or 180 days since the last servicing. - Dual mounting threads - supplied with two mounting threads 1/2" NPT and 9/16" - 12 for convenience and reduced inventory. - Multiple lights, one transformer - up to three Pure Lights can be operated from one 120V transformer which has screw terminals. Only one electrical outlet is required to monitor multiple points. Each light for 120V is supplied with a 10 ft (3 m) connecting wire. - Red & green LED's - for reliability, two bright Light Emitting Diodes (LED's) are used to indicate above or below threshold status, representing the need for regeneration or replacement of ion exchange resin. / Thornton 24 METTLER TOLEDO US and Canada

27 Introduction Increased Safety for Your Production Process ph ph and ORP Systems Reliable in Pure Water Treatment Applications With many decades of experience in designing ph / ORP electrodes METTLER TOLEDO offers a state-of the-art solution for practically any type of process analytical application. Functional definition ph can be described as a measurement of the relative acidity of a solution. Oxidation reduction potential (ORP) as measured with an ORP electrode, provides an indication of the oxidative state of the solution. It is important to measure, and often to control the ph and/or ORP of a solution for several reasons: To produce products with consistent well defined properties To efficiently produce products at optimal cost To avoid health risks To protect the environment To prevent physical/ chemical damage to materials To meet regulatory requirements To expand scientific knowledge The accurate measurement of ph/ ORP is critical in most industries. Each application has unique physical requirements of chemical, temperature, and pressure resistance and possibly hygienic design. Another factor is what is to be done with the measurement: monitoring only, data logging or process control. ph electrode selection It is important to understand the details of the application before selecting a ph electrode. The table gives an initial glance at the various electrodes available and typical applications. Selection of a ph electrode requires a thorough knowledge of the process. Once the requirements are known, comparison of the electrode specifications detailed in this catalog will identify the appropriate sensor. 26 METTLER TOLEDO US and Canada

38 Thornton Ozone Measurement Systems Provide Accurate Response and Excellent Sensitivity Thornton s dissolved ozone measurement systems show rapid and accurate response to ozone concentrations. The excellent sensitivity gives positive detection of zero ozone after destruction by UV light. Measuring principles Ozone passes through a gas-permeable reinforced membrane of exceptional durability producing an electrochemical reaction and current flow in direct proportion. Behind the membrane is the platinum cathode where ozone reacts to produce the measurement signal. The electrochemical reaction is completed at the silver anode. Full temperature compensation accounts for effects of both membrane permeability and solubility of ozone in water. Important features of an ozone sensor Rapid, accurate response Positive zero detection Low maintenance with drop-in modular membrane Ozone sanitization of pharmaceutical water systems Complete sanitization is achieved by controlling ozonation downstream of the storage tank. A second ozone measurement guarantees the removal of all ozone downstream of UV destruction. Ozone sanitization of semiconductor ultrapure water Ozone sanitization can be controlled by monitoring the ozone concentration downstream of the ozonator and UPW storage tank. To be sure all ozone has been decomposed after UV lights a second ozone measurement can confirm a zero level. Ozone sanitation of bottled water Continuous measurement and control to proper ozone levels of bottled water is a required quality practice that promotes consistent good taste and long shelf life. Ozone sanitization of beverage systems Ozonated water is used in place of chemicals for CIP operations when changing between flavors. Ozone provides cleaning and disinfection without risk of objectionable residuals or byproducts. Transmitter selection Thornton sensors are commonly used together with the M800 multiparameter transmitter and the M300 transmitter. Thornton Dissolved Ozone Sensor METTLER TOLEDO US and Canada 37

The M800 instrument will allow up to two or four 5000TOCi Sensors to be connected to any of the four input channels. Any remaining channels are available for use with any other ISM Sensors. The M800 also provides two pulse input channels for additional flow measurements. The Sensor connects directly to the M800 instrument using standard patch cables. The 5000TOCi Sensor is designed to meet the requirements of today s industrial facilities with its UL rating. Combined with the M800 instrument it provides the most versatile and flexible TOC measurement platform available. Measurement technology UV Oxidation / Differential Conductivity The 5000TOCi Sensor uses proven ultraviolet oxidation with differential conductivity (see Figure 1) as the method to effectively determine TOC concentrations. High performance digital conductivity sensors provide continuous conductivity measurement before and after sample oxidation. This is accomplished using a continuous flow-through spiral quartz tube design that allows the sample to flow continuously through the sensor. This design maximizes exposure to the 185 nanometer UV light, while minimizing measurement response time and providing complete oxidation. This simple and effective design requires no reagents or chemicals and has no moving mechanical components. The formation of hydroxyl radicals in the water during UV exposure produces a mechanism through which bonds in non-ionic organic compounds are broken and oxidization occurs to form products such as carbon dioxide and water. The carbon dioxide dissolves in the water and forms carbonic acid which dissociates into ionic-conductive species. This change in conductivity is associated with TOC (see Figure 2). USP/EP and SST In the Pharmaceutical Water production process, System Suitability Testing (SST) is an essential activity to verify the performance of a Total Organic Carbon monitoring system and to ensure its adequacy for TOC analysis. USP and EP Requirements In the requirements for TOC measurement, the United States Pharmacopoeia and European Pharmacopoeia have established specific Total Organic Carbon (TOC) tests as described in USP General Chapter <643> and EP Chapter , respectively.

52 These chapters provide: Guidance on the methodology for TOC testing Criteria for establishing instrument acceptance TOC limits for the sample to be tested Challenges of System Suitability Testing Because organic carbon appears in various forms in nature and subsequently in water treatment processes, a wide variety of oxidation states and chemical forms are found in these systems. The goal of System Suitability Testing is to challenge the TOC measurement technique by verifying that two chemicals of very different chemical properties respond equally. In this case, the two chemicals specified in the pharmacopoeial chapters are sucrose and 1,4-benzoquinone. Because of their unique and different chemical structure, sucrose and 1,4-benzoquinone challenge the bondbreaking and oxidation capability of the TOC measurement technology. These solutions are commonly referred to as easy to oxidize and hard to oxidize chemicals, respectively. In addition to sucrose and 1,4-benzoquinone, reagent water (the water used to manufacture the sucrose and 1,4-benzoquinone solutions) is analyzed during the suitability testing. How is TOC System Suitability Verified? Once the measurements of sucrose, 1,4-benzoquinone and reagent water are complete, a simple calculation is applied: 1. Calculate the limit response by subtracting the Reagent Water (RW) TOC response from the response of the Sucrose (RS) Standard Solution. This is RS RW. 2. Calculate the corrected System Suitability Solution response by subtracting the Reagent Water TOC response from the 1,4-benzoquinone TOC response. This is RSS RW. 3. Fill in the responses to the following formula: Feature Response Efficiency (%) = 100 RSS RW RS RW Response efficiency must fall within the limits as established in the table below: System Suitability Acceptance: 85 % to 115 % The TOC measurement system passes system suitability testing if the response efficiency is greater than or equal to 85 % and less than or equal to 115 %. 5000TOCi Number of TOC sensors per transmitter 4 Measurement Range Transmitter Multi-parameter Plug and Measure USP, EP, JP and Ch.

65 Introduction Trace Contamination Measurement Sodium/Silica Sodium and Silica Measurements Reduce Corrosion and Deposition Long-term efficient power generation requires careful surveillance to guard against corrosive and depositing conditions and to assure conformance with EPRI, VGB or other guidelines. Our sodium and silica analyzers provide highly sensitive monitoring of steam quality to prevent corrosion and deposition on turbines. These analyzers are also excellent for detecting condenser leaks and condensate polisher breakthroughs. Sodium Analyzers The Thornton 2300Na and 2301Na Sodium Analyzers offer a new design for a traditional measurement for pure water treatment and power cycle chemistry monitoring, providing assurance of water purity to minimize corrosion. Early detection of trace contamination is enabled with minimal operator supervision. The sample passes through an overflow assembly that assures precise pressure and flow regulation. The flowrate is set by a needle valve and rotameter at only 40 ml/min, saving pure water and reagent. DIPA vapor diffuses into the sample without contamination through gas-permeable tubing. The reagent raises the ph of the sample to approximately 11 ph to enable the ion-selective electrode to respond only to sodium ion concentration. The 2301Na Analyzer enables use of either DIPA or Ammonium hydroxide for this purpose. The sample passes through the sodium sensor flow tube and into the larger flow chamber containing a combination probe including the reference electrode, a ph electrode and temperature compensator. The ph measurement is always displayed, providing in-process confirmation that the correct amount of reagent has been added to the sample. The reference and temperature compensator are shared with the sodium measurement. The sample then passes to drain. Electrodes incorporate Intelligent Sensor Management capability which stores all identification, calibration, and real-time predictive maintenance data within the sensor. 2300Na Sodium Analyzer 2301Na Sodium Analyzer Measurement Range ,000 ppb ,000 ppb Grab Sample Yes Add-on Option Calibration Unattended, Automatic Manual Automatic Na Sensor Conditioning Yes No ph Check* Yes Yes Low Electrode Etching Frequency Yes Yes Low Reagent Consumption Yes Yes Reagent Used DIPA DIPA or NH4OH Accuracy Enclosure ±10% of reading; ±0.05ppb DIPA Fully enclosed, Full or Half Door models *ph Check assures reagent addition is taking place for interference- free measurement ±10% of reading; ±0.1ppb DIPA ±10% of reading; ±0.1ppb NH4OH Full enclosure or Panel assembly models 2300Na Sodium Analyzer The 2300Na provides automatic, walkaway calibration with automatic sensor conditioning which saves time and assures reliable operation. A choice of enclosures are available to keep controls protected in dirty environments or conveniently accessible in clean areas. 2301Na Sodium Analyzer The 2301Na Sodium Analyzer offers a panel-mounted design with available feature options such as grab sample, filtration, and analyzer enclosure allowing the user to select those that best fit their need. The 2301Na also allows for either DIPA or ammonium hydroxide to be used as a reagent to comply with your plant operations and safety needs. 64 METTLER TOLEDO US and Canada

66 2800Si Silica Analyzer The Thornton 2800Si Silica Anaylzer is a reliable on-line instrument designed specifically for pure water treatment and power cycle chemistry monitoring. This Analyzer provides assurance of water purity to optimize ion exchange production of pure water and to minimize silica deposition in turbines. Early detection of trace contamination is enabled with minimal operator supervision. The analyzer allows sample to pass through an overflow assembly ensuring that a fresh sample is available to start each measurement cycle. A rinse period purges the previous sample from the reaction/ measurement chamber and fills it with the fresh sample. The measurement is zeroed. Then, reagents are metered in and reaction time allowed to produce a color change proportional to silica concentration. Where phosphates are present, an additional reagent is included to minimize interference. The measurement is made, the display and outputs are updated and the cycle repeats.

Typical Applications Ultrapure water monitoring at ppb silica levels can assure the highest quality water is being delivered. Silica breakthrough of polisher anion resin is detected at very low ppb levels and contaminated water can be diverted before it reaches critical areas. Pure water treatment anion exchange monitoring detects the first breakthrough of silica to trigger regeneration before contamination reaches subsequent treatment stages. Power steam quality monitoring protects turbines from silica deposition and resulting imbalance, loss of capacity and efficiency. Silica measurement an control may also be needed to meet turbine manufacturer warranty requirements. Power condensate polisher monitoring can detect the need for regeneration at low ppb levels before feedwater is significantly contaminated.
