Revision 3 OneWireless XYR 6000 SmartCET Corrosion Transmitter User's Manual iii 6/24/08 About This Document This document describes preparation, operation and maintenance of the XYR 6000 Wireless Corrosion Transmitters. Mounting, installation and wiring are covered in other documents. Honeywell does not recommend using devices for critical control where there is a single point of failure or where single points of failure result in unsafe conditions. OneWireless is targeted at open loop control, supervisory control, and controls that do not have environmental or safety consequences. As with any process control solution, the end-user must weigh the risks and benefits to determine if the products used are the right match for the application based on security, safety, and performance. Additionally, it is up to the end-user to ensure that the control strategy sheds to a safe operating condition if any crucial segment of the control solution fails.

1. Introduction 1.1. Purpose Revision 3 OneWireless XYR 6000 SmartCET Corrosion Transmitter User's Manual 1 6/24/08 1. Introduction 1.1 Purpose This manual describes the Honeywell OneWireless XYR 6000 SmartCET Corrosion Transmitter function, operation and maintenance. 1.2 Scope The manual includes: • Details of topics that relate uniquely to the Honeywell XYR 6000 Corrosion Transmitter, • This manual does not cover installation, mounting, or wiring. See XYR 6000 Transmitter Quick Start Guide (document 34-XY-25-21). 1.3 OneWireless network overview OneWireless is an all digital, serial, two-way communication mesh network that interconnects industrial field sensors to a central system. OneWireless has defined standards to which field devices and operator stations communicate with one another. The communications protocol is built as an "open system" to allow all field devices and equipment that are built to OneWireless standard to be integrated into a system, regardless of the device manufacturer. This interoperability of devices using OneWireless technology is to become an industry standard for automation systems. 1.4 About the transmitter The XYR 6000 SmartCET Corrosion Transmitter is furnished with OneWireless interface to operate in a compatible distributed OneWireless system. The transmitter will interoperate with any OneWireless-registered device. The transmitter includes OneWireless electronics for operating in a 2.4GHz network. It features function block architecture. The transmitter measures the process corrosion and transmits a digital output signal proportional to the measured variable. Its major components are an electronics housing as shown in Figure 1. The XYR 6000 transmits its output in a digital OneWireless protocol format for direct digital communications with systems. The Process Variable (PV) is available for monitoring and alarm purposes. The sample time can be configured to calculate the corrosion variables every 30 seconds, or every 1, 2, 3, 4, 5 minutes. This parameter is independent of the publish rate, which has a configuration time of 30 seconds. If the sample time and publish rate are both set to 30 seconds, the corrosion transmitter will continuously calculate corrosion measurements and publish a new measurement (all four variables) at each publish rate interval (every 30 seconds). This configuration will result in minimal battery life but provides almost real time corrosion information. If the sample time is set for five minutes, all four corrosion variables will be calculated and published within the next 30 second publish rate interval, however the transmitter corrosion measurement will then go to sleep for 4.5 minutes, until it is time to start the next sample. This configuration will result in maximum battery life and is the default configuration. Figure 1 shows a block diagram of the XYR 6000 SmartCET Corrosion transmitter’s operating functions.

6. Troubleshooting 6.1. Diagnosis of Transmitter Health from Measurement Data 34 OneWireless XYR 6000 SmartCET Corrosion Transmitter User's Manual Revision 3 6/24/08 6. Troubleshooting 6.1 Diagnosis of Transmitter Health from Measurement Data The output from the corrosion transmitter can provide insight into the health of the transmitter operation. Table 12 shows the output expected for each variable when the transmitter is operating properly and the table also shows an indication when a probe short condition exists and when no probe is connected. Table 12 Diagnosis of Transmitter Health Description Transmitter output variable General Corrosion Pitting / Localized Corrosion Probe short No probe connected Corrosion rate PV Across range Across range Maximum value Note 1. ~ 0 Note 3. Pitting Factor SV <0.1 >0.1 <0.001 ~ 1 B value TV (Stable) Note 2. (Unstable) Note 2. (Unstable) Note 2. (Unstable) Note 2. Corrosion Monitoring Index QV Across the range Across the range (~ 0) Note 2. ~ 0 Note 1: Corrosion rate maximum will depend on the material constants and surface area entered. From a measurement perspective, it relates to the absolute value of the polarization resistance of the working electrode. If the polarization resistance is very low (<10 ohms), the instrument will be close to current saturation. For optimal operation it is preferable to maintain the polarization resistance of the working electrode at values of >100 ohms. This may be achieved to some extent by changes to the surface area of the working electrode, thereby optimizing the span of the corrosion measurement. Note 2: Items shown in brackets are general statements. No specific value can be provided. Note 3: An exact zero value will not be achieved. It will be almost zero or very small, for example, 0.001 mpy. Under conditions when general corrosion is prevalent on the material being monitored, the measured corrosion rate observed as the primary variable (PV) may be expected to show evidence of being stationary for a short term. In these cases the corrosion rate will tend to exhibit only slight variation in the short term, perhaps over periods of hours or longer. Any slight process change, such as temperature variability is often reflected in the corrosion rate behavior. Larger excursions in the corrosion rate may be experienced if there are more pronounced changes to the environment, for example due to flow rates or changes in composition. The secondary variable, Pitting Factor, will typically exhibit a low value under these conditions (for example, <0.01), although it may exhibit some short term response to abrupt changes in the environment, for example sudden changes in temperature, flow rate or fluid composition. The tertiary variable (the B value) will usually fall in a range of 0.010 to 0.030 volts, and will be stable. The quaternary variable (Corrosion Mechanism Indicator) is largely dependant on the type of material being studied, but generally, if active corrosion is being observed (>5mpy), it will tend to be significantly larger than the case for very low corrosion rates.
6. Troubleshooting 6.2. General troubleshooting procedures Revision 3 OneWireless XYR 6000 SmartCET Corrosion Transmitter User's Manual 35 6/24/08 If low general corrosion rates are being observed, which are close to instrument baseline (< 0.05 mpy), the Pitting Factor may appear artificially high (for example, > 0.01). When localized corrosion is occurring, the observed general corrosion rate values may be in the range 0.1 to 10 mpy or higher, depending on the material and the environment. The Pitting Factor will tend to exhibit higher magnitude peaks of activity during pit initiation events, whereas propagating pits may be associated with a general increase in the observed corrosion rate and lower levels of Pitting Factor (<0.1). The general corrosion rate in the case of propagating pits often exhibits short term variation and is noticeably less stable than the case for general corrosion. Pitting is often accompanied by increased variability in the B value. With increasing degrees of pit propagation, the CMI values will also tend to increase. 6.2 General troubleshooting procedures The XYR 6000 SmartCET transmitter is designed to operate over a broad range of corrosion rates. However, most problems associated with the corrosion rate calculation arise when the actual corrosion rate is extremely high, and there is likelihood that the instrument is approaching or exceeding its stated operating limits. In some circumstances, this can be remedied by using sensors with a smaller surface area. Another factor to be considered is severe diffusion limiting or mass transport control of the corrosion processes. In this case the B value determination may become difficult, and erratic behavior with very high values may be observed. Troubleshooting procedures that deal with this condition and general situations are shown in Table 13. Table 13 Troubleshooting procedures Symptom Possible cause Action Corrosion rate values are very low and do not change 1. Probe or probe cable fault – bad connection to probe electrodes 2. Transmitter fault 1. Check continuity with test cell connected at probe end of cable. May be necessary to remove probe and carry out continuity checks between connecting pins and probe sensing elements. 2. Check with test cell connected directly to transmitter terminals. Consult with the factory for additional information.
6. Troubleshooting 6.2. General troubleshooting procedures 36 OneWireless XYR 6000 SmartCET Corrosion Transmitter User's Manual Revision 3 6/24/08 Symptom Possible cause Action Corrosion rates are very high, Pitting Factor very low, and B values are very low. This problem could be due to a shorting condition between probe sensing elements 1a. Disconnect probe and the corrosion rate should fall. 1b. Remove probe and physically check for electrode to electrode contact. 1c. May be caused by the presence of conductive corrosion deposits for example, iron sulfide (B value very low). 2. Use probe with smaller surface area. Corrosion rate switches abruptly from high to very low levels, Pitting Factor is very high, and the B value goes to the current default value. This situation is symptomatic of when the (internal) polarization resistance calculation has apparently gone to a negative value, with the result that the corrosion rate is indeterminate and a default low value is returned. Apparent negative polarization resistances may occur in situations where the corrosion rates are very high and the electrode area is incorrect for the process situation. The electrodes could be too large. Investigate using electrodes with a smaller area. Another possible cause may be due to an asymmetrical response of the electrodes, for example due to crevice corrosion occurring on one of the electrodes. The electrodes should be inspected in this case. All the variables (corrosion rate, Pitting Factor, B value and CMI) are suspect and could be in error. Consult with the factory for additional information. All corrosion variables are very unstable exhibiting one or more of the following: Corrosion rate unstable, may drop to very low values Pitting Factor low when corrosion rate high and vice versa. B values unstable switching between -20 and 100. CMI unstable switching from very low value 0, to large value for example, > 5000. These symptoms are typically caused by high and variable corrosion rates in the process environment, hard diffusion limiting processes, and/or electrode surface areas being too large for the application. Disconnect probe. Corrosion values should return to baseline levels. Check with test cell, transmitter should give a standard response. Electrode surface area could be incorrect for the application. Contact a Honeywell corrosion specialist to review the application. Corroding systems with real diffusion / mass transport limiting scenarios are problematic monitoring situations.
6. Troubleshooting 6.3. Recommended operating conditions Revision 3 OneWireless XYR 6000 SmartCET Corrosion Transmitter User's Manual 37 6/24/08 Symptom Possible cause Action Inaccurate readings. Possible wrong parameter values for the probe’s electrode area. Check the following parameter values in Wireless Builder. • Electrode area • Atomic mass • Density • Electrons See page 10 for probe parameters. 6.3 Recommended operating conditions The XYR 6000 SmartCET transmitter utilizes electrochemical techniques that are applicable to a wide range of corrosive conditions. The following table provides the applicable operating envelope for XYR 6000 SmartCET with additional comments when the operating range is outside envelope. Table 14 Recommended operating conditions Measurement Range Comments Corrosion rate 0-250 mpy dependent upon the electrode surface area, typically in range of 1 to 10 cm2. (Default URV setting is 100 mpy and the electrode area is 4.75 cm2.) Higher sensitivity at low corrosion rates may be achieved by using larger electrodes - consult factory for additional information. The higher corrosion rate range is achieved with appropriately sized electrodes (for example, small areas). If symptoms listed in Table 13 occur, the B value should be fully reviewed and analyzed before providing a corrosion rate estimate. It is recommended to qualify the rate estimate against mass loss from electrodes – consult factory for additional information. Pitting Factor 0.001 to 1. With low corrosion rates, the Pitting Factor may appear artificially high due to very low observed general corrosion rates – consult factory for additional information. B value Expected range: 5 to 60mV (0.005 to 0.06V). Low values may be due to formation of surface films having redox behavior (for example, Iron sulfide). The electrode essentially starts to become non-polarizable.
6. Troubleshooting 6.3. Recommended operating conditions 38 OneWireless XYR 6000 SmartCET Corrosion Transmitter User's Manual Revision 3 6/24/08 Measurement Range Comments High values predominantly may be due to diffusion limiting processes. As the electrochemical processes become more diffusion limiting, the B value may not achieve a stable value. Applying the B value from this type of situation (for example, updating the default value) is not recommended. Consult with the factory for additional information. Corrosion Mechanism Indicator Expected range: 0 to 2000. Values are dependent on material and environment.
7. Corrosion measurements 7.1. Overview Revision 3 OneWireless XYR 6000 SmartCET Corrosion Transmitter User's Manual 39 6/24/08 7. Corrosion measurements 7.1 Overview The XYR 6000 SmartCET corrosion transmitter outputs four corrosion measurements. • General Corrosion Rate - average or general corrosion rate, and is generally expressed in mils per year (mpy) or millimeters per year (mmpy). • Pitting Factor - dimensionless number that indicates the presence of a pitting (localization) corrosion environment. • B value - expressed in millivolts per decade, and is commonly also known as the Stern Geary constant. • Corrosion Mechanism Indicator – indicator representing health of the probe in regard to fouling or wear. The values are all updated every 30 seconds, which is the total measurement cycle time of the instrument. The values for the General Corrosion Rate, the Pitting Factor and the Corrosion Mechanism Indicator are set to output the most recent values. 7.2 General corrosion rate The Linear Polarization Resistance (LPR) technique is used to calculate the General Corrosion Rate. This calculation is usually the prime variable of interest since it reflects the overall rate of metallic corrosion. Corrosion may be directly related to operational parameters such as temperatures, flow, chemical composition, etc. The XYR 6000 SmartCET uses three electrodes that are referred to as the working, counter and reference electrodes. A low frequency sinusoidal voltage excitation is applied to the working electrode with respect to the reference electrode, and the current is measured and analyzed (on the counter electrode) synchronously with the applied signal. Given a sinusoidal pattern, the working electrode becomes positively charged and then negatively charged (in other words, polarized positively and negatively). It is a DC voltage applied in a sinusoidal pattern and resembles an AC pattern. The peak-to-peak value of the sinusoidal wave is 50mV. Strictly, this is a measurement of the real part of the low frequency impedance of the working electrode. This method of analysis is selected due to its superior noise rejection, which is particularly useful when studying corroding systems since they exhibit varying degrees of intrinsic noise. The result is equivalent to measuring the linear polarization resistance of the working electrode. With this measurement, the corrosion current (hence, the corrosion rate) is inversely proportional to the polarization resistance. This measurement also employs the Stern-Geary approximation where the Stern-Geary constant (or B value) is the proportionality constant. In practice, with no prior knowledge of the system, the “default” value of B for this type of measurement is typically chosen to be in the range 25 to 30 mV; in reality, the value of B is system-dependent. Use of the default B value may result in the absolute corrosion rate being somewhat in error, but in some instances, it is the general trend of the corrosion rate that could be of interest instead of the absolute value. Working method summary There are three electrodes in use, which are designated working electrode (WE), counter electrode (CE) and reference electrode (RE). A sinusoidal DC voltage is applied on the WE (voltage is varied).
7. Corrosion measurements 7.3. B value 40 OneWireless XYR 6000 SmartCET Corrosion Transmitter User's Manual Revision 3 6/24/08 In turn, the current response is measured between the CE and WE. The ratio of voltage to current provides the polarization resistance. The polarization resistance is not a true resistance in the traditional sense, but can be treated as such in describing the LPR technology. The corrosion current is inversely proportional to the polarization resistance. How does an electrical model represent a corrosion process? What makes corrosion look like an electrical system? Corrosion comprises an anodic process and a cathodic process, i.e. electrochemical processes that occur at anodic and cathodic sites on the metal surface. When corrosion is occurring, there is an increase of ionic flow between the anodic and cathodic sites (i.e. Faradaic process). A non-corrosive system would not exhibit any ionic flow. Table 15 shows the relationship between corrosion rate, environment characterization and the recommendation for getting accurate General Corrosion Rate measurements. Table 15 Corrosion Rate and Environment Characterization Corrosion Rate Environment Comments >200 mpy Highly conductive, highly corrosive This could be at upper level of XYR 6000 accuracy range. If used in this environment, electrodes with small area should be used (for example, 1cm2). 1-200mpy Average corrosion rate Use correct probe type according to process application. 0.01-1mpy Low conductivity or passive system Electrodes with large area should be used (for example, 10cm2). <0.01mpy Extreme passivity or low conductivity (for example, organic medium) This could be at lower level of XYR 6000 accuracy range. If used in this environment, electrodes with large area should be used (for example, 10cm2). 7.3 B value The B value represents a correction factor ‘constant’ that is determined by the mechanism and kinetics of the corrosion process. In a dynamic process, research has shown that the B value is not constant. For example, the B value for a sour system with a microbiological influence on corrosion activity could be 4mV. The average “industry-accepted” default B value is typically between 25 and 30mV. Houston tap water gives a B value of 15mV. A severely scaled system (i.e. inorganic scale deposits on the metal surface) would show a B value of around 100 mV. By evaluation of the non-linearities in the current response from the LPR measurement, it is possible to determine a B value for the system being studied. This involves the analysis of the higher order harmonic content of the current response, and computation of a value of B for the system being studied. With knowledge of the B value it is possible to refine the LPR-generated corrosion rate estimate, since the uncertainty regarding the standard (default) B value is removed. The B value is directly related to the mechanistic properties of the component anodic and cathodic corrosion processes. The anodic process is essentially the metal oxidation and the cathodic process is, for example, the oxygen reduction or hydrogen evolution. These are essentially non-linear processes, and the current will typically (but not always) have a logarithmic dependence on the applied voltage. The B value is a composite of the individual anodic and cathodic Tafel slopes.

Pitting factor Revision 3 OneWireless XYR 6000 SmartCET Corrosion Transmitter User's Manual 41 6/24/08 Potential Ecorr ba (anodic Tafel slope) bc (cathodic Tafel slope) Figure 8 Individual Anodic and Cathodic Tafel Slopes The B value is calculated using the following equation: B = ba*bc/2.303*(ba+bc) So these individual slopes are representative of non-linear processes. In the calculation of the general corrosion rate, the B value approximation assumes that the processes are essentially linear for a small applied potential, for example: 10 – 20 mV away from the corrosion potential and only takes into account the first order (linear) processes. The harmonic distortion analysis takes into account the second and third order processes, i.e. it is similar to fitting a polynomial to x3, but we use the higher frequency harmonic components to analyze rather than trying to fit a polynomial – it’s a much better analysis route. XYR 6000 SmartCET uses Harmonic Distortion Analysis (HDA) to calculate the ‘true’ B value. With an accurately computed B value, the default B value used in the LPR calculation can be changed thus enabling a more accurate corrosion rate calculation to be made.

B value indeterminate. 7.4 Pitting factor The Pitting Factor is a measure of the overall stability of the corrosion process, and is obtained from a measurement of the intrinsic current noise of the working electrode, and comparing this measurement to the general corrosion current obtained from the LPR measurement (for example, general corrosion rate calculation). Log (Current density) Log (Icorr)
7. Corrosion measurements 7.5. Corrosion mechanism indicator 42 OneWireless XYR 6000 SmartCET Corrosion Transmitter User's Manual Revision 3 6/24/08 General corrosion processes typically have low levels of intrinsic noise, with the ratio of noise to the general corrosion current typically being ≤1% (Pitting Factor ≤0.01). With the onset of instability (pit initiation), localized corrosion occurrence leads to increasingly higher levels of current noise with respect to the general corrosion current such that the Pitting Factor may reach a value of 1. The Pitting Factor can be viewed as the probability that the corrosion mechanism is localized. Spontaneous changes in the environment may also cause the instantaneous value of the Pitting Factor to approach a value of 1 in the short term; however, for localized corrosion, the Pitting Factor will remain unstable and secondary evidence may be observed in terms of the overall stabilities of both the general corrosion rate estimate and the B value. XYR 6000 uses electrochemical noise (ECN) to calculate the Pitting Factor. A useful analogy to explain the difference between general corrosion and localized corrosion (Pitting Factor) is that of a flashlight with its beam constantly ON (general corrosion) and one that is flickering (localized corrosion). Table 17 Pitting Factor Values PF Value Comments 0.1 or higher Pitting/localized corrosion – initiation (Note: check corrosion rate value; if very low, PF could be misleading). 0.01 to 0.1 Intermediate level; general corrosion but check PF does not increase above 0.1. 0.01 or lower General corrosion. 7.5 Corrosion mechanism indicator The metallic corroding interface is complex and dynamic. The general corrosion rate, the B value, and the Pitting Factor all help to characterize the Faradaic corrosion processes (current flow that is the result of electrochemical process) quite thoroughly. However, in order to be more complete in the analysis of the electrochemical response there is at least one more factor which needs to be taken into account. During the measurement of the low frequency impedance, a reactive, phase shifted component of the current response may be detected. This is a consequence of the physical nature of the metal/environment (electrolyte) interface, and may reflect mechanistic properties such as the presence of films, film formation and surface adsorption processes. The values obtained are likely to be characteristic of a particular system being studied. For example sulfide filming may cause the reactance to become more positive, whereas adsorption processes may cause the values to go negative. The absolute values obtained may provide the corrosion expert with extra knowledge regarding the corrosion behavior of any particular system. Understanding CMI values The CMI is a qualitative indicator of whether a surface film is present or not. If there is no film and only corrosion is present, the CMI will have an intermediate value. Inorganic scale, or thick passive oxide films with little or no conductivity, will show a low CMI value. Analysis of the Corrosion Mechanism Indicator is shown in Table 18.
