9. Empirical Calibrations page A 34 Solid Applications page A 40 Application of the Hygrometer 900 901E A 1 June 2004 Moisture Monitor Hints GE Panametrics hygrometers using aluminum oxide moisture probes have been designed to reliably measure the moisture content of both gases and liquids The measured dew point will be the real dew point of the system at the measurement location and at the time of measurement However no moisture sensor can determine the origin of the measured moisture content In addition to the moisture content of the fluid to be analyzed the water vapor pressure at the measurement location may include components from sources such as moisture from the inner walls of the piping external moisture through leaks in the piping system and trapped moisture from fittings valves filters etc Although these sources may cause the measured dew point to be higher than expected it is the actual dew point of the system at the time of measurement One of the major advantages of the GE Panametrics hygrometer is that it can be used for in situ measurements i e the sensor element is designed for installation directly within the region to be measured As a result the need for complex sample systems that include extensive piping manifolds gas flow regulators and pressure regulators is eliminated or greatly reduced Instead a simple sample system to reduce the fluid temperature filter contaminants and facilitate

17. M Series Aluminum Oxide Moisture Sensors have been designed to minimize the affect of corrosive gases and liquids As indicated in the Materials of Construction section of this appendix no copper solder or epoxy is used in the construction of these sensors The moisture content of corrosive gases such as H5S SO cyanide containing gases acetic acid vapors etc can be measured directly Note Since the active sensor is aluminum any fluid which corrodes aluminum will affect the sensor s performance By observing the following precautions the moisture probe may be used successfully and economically 1 The moisture content of the corrosive fluid must be 10 PPMv or less at 1 atmosphere or the concentration of the corrosive fluid must be 10 PPMv or less at 1 atmosphere 2 The sample system must be pre dried with a dry inert gas such as nitrogen or argon prior to introduction of the fluid stream Any adsorbed atmospheric moisture on the sensor will react with the corrosive fluid to cause pitting or corrosion of the sensor 3 The sample system must be purged with a dry inert gas such as nitrogen or argon prior to removal of the moisture probe Any adsorbed corrosive fluid on the sensor will react with ambient moisture to cause pitting or corrosion of the sensor 4 Operate the sample system at the lowest possible gas pressure Using the precautions listed above the hygrometer has been used to successfully measure the moistu

20. moisture changes will probably be observed because the contaminating liquid barrier will decrease the rate of transport of the water vapor to the sensor and reduce its response time Particulate matter with a high density and or a high flow rate may cause abrasion or pitting of the sensor surface This can drastically alter the calibration of the moisture probe and in extreme cases cause moisture probe failure A stainless steel shield is supplied with the moisture probe to minimize this effect but in severe cases it is advisable to install a Teflon or stainless steel filter in the fluid stream Application of the Hygrometer 900 901 E A 7 June 2004 Non Conductive Particulates cont On rare occasions non conductive particulate material may become lodged under the contact arm of the sensor creating an open circuit If this condition is suspected refer to the Probe Cleaning Procedure section of this appendix for the recommended cleaning procedure Conductive Particulates Note Metallic particles carbon particles and conductive liquid droplets are typical of this category Since the hygrometer reading is inversely proportional to the impedance of the sensor a decrease in sensor impedance will cause an increase in the meter reading Thus trapped conductive particles across the sensor leads or on the sensor surface which will decrease the sensor impedance will cause an erroneously high dew point reading The most common p

22. sensor itself can not lead to such problems Application of the Hygrometer 900 901E A 3 June 2004 Pressure GE Panametrics hygrometers can accurately measure dew points under pressure conditions ranging from vacuums as low as a few microns of mercury up to pressures of 5000 psig The calibration data supplied with the moisture probe is directly applicable over this entire pressure range without correction Note Although the moisture probe calibration data is supplied as meter reading vs dew point it is important to remember that the moisture probe responds only to water vapor pressure When a gas is compressed the partial pressures of all the gaseous components are proportionally increased Conversely when a gas expands the partial pressures of the gaseous components are proportionally decreased Therefore increasing the pressure on a closed aqueous system will increase the vapor pressure of the water and hence increase the dew point This is not just a mathematical artifact The dew point of a gas with 1000 PPMv of water at 200 psig will be considerably higher than the dew point of a gas with 1000 PPMv of water at 1 atm Gaseous water vapor will actually condense to form liquid water at a higher temperature at the 200 psig pressure than at the 1 atm pressure Thus if the moisture probe is exposed to pressure changes the measured dew point will be altered by the changed vapor pressure of the water It is generally advant
23. sensor removal is all that is needed Whether the sensor is installed in situ or in a remote sampling system the accuracy and speed of measurement depend on the piping system and the dynamics of the fluid flow Response times and measurement values will be affected by the degree of equilibrium reached within system Factors such as gas pressure flow rate materials of construction length and diameter of piping etc will greatly influence the measured moisture levels and the response times Assuming that all secondary sources of moisture have been eliminated and the sample system has been allowed to come to equilibrium then the measured dew point will equal the actual dew point of the process fluid A 2 Application of the Hygrometer 900 901E June 2004 Moisture Monitor Hints cont Some of the most frequently encountered problems associated with moisture monitoring sample systems include the moisture content value changes as the total gas pressure changes the measurement response time is very slow the dew point changes as the fluid temperature changes the dew point changes as the fluid flow rate changes GE Panametrics hygrometers measure only water vapor pressure In addition the instrument has a very rapid response time and it is not affected by changes in fluid temperature or fluid flow rate If any of the above situations occur then they are almost always caused by a defect in the sample system The moisture
24. the Sample System In order to operate the self contained sample system correctly first determine if you need to make measurements at atmospheric pressure or at process pressure After determining the pressure use the appropriate section that follows to start up and shut down the sample system Note The maximum allowable pressure for the self contained sample system for the Series 35 IS is 4500 psig At Atmospheric Pressure 1 Begin with the Series 35 IS inlet and outlet valves in the closed position then open the outlet valve completely 2 Open the inlet valve slightly to allow only a small amount of flow from the process At Process Pressure 1 Begin with the Series 35 IS inlet and outlet valves in the closed position then slowly open the inlet valve fully 2 Open the outlet valve slightly to allow only a small amount of flow Operating the Series 35 IS 3 3 March 2003 Shutting Down the Sample System At Atmospheric or Process Pressure 1 Close the inlet valve completely 2 Wait for the flow from the outlet valve to stop 3 Close the outlet valve to keep the probe sensor from being affected by ambient moisture Powering Up the Series 35 IS To turn on the Series 35 IS press the POWER switch located on the left side of the front panel to the ON position If the battery is depleted see Chapter 4 Troubleshooting to recharge the battery The Series 35 IS displays Loading followed by a series
