1. GENERAL DESCRIPTION

1.1. PURPOSE AND FIELD OF APPLICATION

This manual provides a description of the construction and function of the Hygrovision BL dew point analyzer, model number KRAY2.844.007 (also called HV BL, Hygrovision, device, instrument, and analyzer in the text).

The Hygrovision BL is a compact portable analyzer used to establish the dew point temperature of water and hydrocarbons.

This portable hygrometer (hereinafter analyzer) functions according to the principal of direct measurement. It employs a temperature-controlled mirror upon which condensation forms to establish dew point.

The Hygrovision is one of a series of revolutionary new highprecision chilled-mirror analyzers that are characterized by the inclusion of a supplemental visualization system. This system makes it possible to physically observe the condensation (dew point) process. In addition, this system has two different illumination options, which makes it possible to easily distinguish between water condensation and the formation of hydrocarbon condensates.

1.3. MEASUREMENT PRINCIPLE

The Hygrovision BL is a compact, portable analyzer used for taking automatic and manual measurements of the dew point temperature of water and/or hydrocarbons.

This portable chilled-mirror automatic hygrometer operates according to the principle of direct measurement and employs a temperature-controlled mirror to establish the dew point. During the measurement process the reflectivity of the mirror is measured. As the temperature of the mirror is lowered, its reflectivity begins to go down when the dew point is reached and condensation begins to form. In this process condensates are deposited on the mirror (reflective surface).

A special system uses optical properties to register the formation of this condensate film.

This system utilizes the phenomenon of total refraction to register dew point.

A laser emitting vertically polarized light illuminates the interface of a heterogeneous media (gas) 1 and a reflective dielectric surface (temperature controlled mirror) 2 at a specific angle. This angle is known as Brewster’s Angle.

When the dew point mirror (dielectric surface) is clean, in other words, when no condensate has formed, the polarized light rays falling on the interface between the gas and the mirror’s surface are completely refracted. As a result no light is reflected onto either of the photo detectors (F1 and F2). This results in a null signal from the sensors (ILLUSTRATION 1). With the microscope attached, total refraction can be observed visually under both side lighting and vertical lighting. Under side lighting*, the surface of the dielectric mirror appears black (illustration 2). Under microscope (vertical) lighting the mirror’s surface appears light blue (ILLUSTRATION 3).

*Please note: the side-lighting unit and the laser are not the same component.

In the case of water vapor, as the temperature of the mirror is lowered and condensation droplets begin to form, the angle at which the polarized light strikes the surface changes with the result that refraction no longer occurs. Instead, the light rays are reflected and scattered. The photoelectric registration system records an increase in the intensity of the light detected by the photo detector located in position F1 (ILLUSTRATION 4). The signal intensity (aka signal level) is dependent on the amount of water condensation.

Under side lighting, water condensation appears in the form of an accumulation of luminous, somewhat similarly sized red droplets

in the middle of the mirror’s surface (ILLUSTRATION 5). Under vertical lighting this condensation appears as an accumulation of little round black spots evenly distributed over the entire surface of the condensation mirror (ILLUSTRATION 6).

In the case of hydrocarbons, precipitated condensates accumulate in the form of a thin film on the surface of the mirror (Illustration 7). The building of a contiguous condensate layer (2) on the mirrors surface (1) results in a change in the angle at which the polarized light strikes the surface of the dielectric mirror.

The beam of light emitted by the laser is partially reflected as it encounters the gas/condensate interface (3/2). This set of light rays is then registered by the photo detector at position F2.

At the same time, due to the condensate film’s high degree of transparency, a set of slightly refracted light rays, passes through the gas/condensate interface and is reflected as it strikes the condensate/mirror interface (2/1). These light rays are then also registered by the photo detector at position F2. This second set of rays is now slightly out of phase with the first set.

As a result, the registration system records two distinct light signals detected by the F2 sensor. These two light signals create an interference pattern due to the slight phase difference.

The intensity of the light signal detected by the sensor is directly dependent on the quantity of hydrocarbon condensates in the condensation film.

The hydrocarbon condensation process can only be observed visually under vertical illumination. In contrast to water vapor condensation, the process of HC condensation cannot be made visible under side lighting, so even though the sidelight is activated, the mirror remains dark (ILLUSTRATION 2).

Hydrocarbons up to and including Heptanes form rainbow colored spots. These spread out until they link up to form one continuous thin iridescent film. (ILLUSTRATION 8). If the mirror continues to be cooled further, this thin iridescent film becomes a colorless plastic layer covering the entire condensation mirror’s surface.

Octane and heavier hydrocarbons condense onto the mirror in the form of small dark semi-transparent dots. With further cooling, these dots grow to become small droplets and spots (ILLUSTRATION 9).

Continuation of the cooling process causes these small droplets to continue to grow, eventually forming large colorless drops of condensate on an iridescent background.

For further images of water and hydrocarbon condensation refer to Appendix N.

1.4. ANALYZER CONSTRUCTION

The analyzer’s cold-body housing (see ILLUSTRATION 10 and ILLUSTRATION 11) consists of the high-pressure chamber (1) a sample sized receptacle (hereafter in the text the measurement cell (2)) a removable visualization system with 40 power magnification (hereafter in the text microscope (16) and an electronic module with an integrated touch screen display (10). The analyzer’s high-pressure chamber is designed for a working pressure of up to 300 bar, and serves to supply and remove the sample gas that passes over the condensation mirror. In order to observe the condensation process, the high-pressure chamber is fitted with a small window upon which the visualization system can be mounted.

The microscope is mounted directly onto the Hygrovision’s highpressure chamber.

The electronic module controls the analyzer’s processes (cooling/heating); records the mirror temperature and regulates the photoelectric registration system.

The Hygrovision BL is operated by means of control buttons and the touch screen display.

Recorded dew point values can be downloaded by means of an IR port and an RS 485 interface.

In order for the analyzer to operate independent of an external power supply, a slot for a storage battery is integrated into the Hygrovision‘s housing, as is a socket for connecting the unit to an external power supply (12–32V, 15W).

1.12. EXPLOSION SAFETY PROVISIONS

The analyzer is fitted with a flameproof enclosure and intrinsically safe electrical circuitry to provide safety against explosion (Table 1).

Other design features that ensure the Hygrovision BL is protected against explosion are:

Spark arresting insulation barriers that ensure the intrinsic safety of the electrical connections at the control buttons.

Bypass diodes and resistors that ensure the intrinsic safety of the electrical circuit connected to the display unit. These elements reduce the electrical current and voltage to the values allowed by GOST R 52350.11 for electrical devices in Group II B. This reduction applies for both normal and emergency operation modes. Electrical sparking is prevented through a combination of resistors and a fuse module.

The sum of the electrical capacity and the inductivity of the electrical circuit that connects the Hygrovision BL to external components via their individual intrinsically safe plugs conform to the values required by GOST R 52350.11.

Optoelectronic coupling provides galvanic separation of the signal and the internal circuitry of the Hygrovision BL.

Electrical clearances and seepage, and the stability of the electrical insulation of the intrinsically safe circuitry are in accordance with the requirements of GOST R 52350.11

The electrical load does not exceed two thirds of the nominal capacity of components that ensure intrinsic safety.

The construction and electrical properties of the LED conform to the specifications stated in GOST R 52350.0 and GOST R 52350.1.

The maximal temperatures generated through internal heating, to which the electrical components and the housing of the Hygrovision BL are exposed do not exceed those allowed in GOST R

52350.0 for temperature class T5.

The HV BL’s electronics unit connection points through the flameproof enclosure meet the requirements of GOST R 523 50.1 for electrical apparatus of subgroup II B.

Lock nuts and adhesives are used to protect against the loosening of the screws, bolts, and nuts that secure the various elements of the flameproof enclosure as well as the conductor and grounding terminals. Similarly, locking devices are used to secure self-threading connectors. The heads of external fixing screws are recessed and can only be accessed using a special tool.

Cable entry points ensure that conductors have a stable and durable connection. Fasteners comply with the requirements of the GOST R 52350.1 – 2005 directive.

The mechanical strength of the flameproof enclosure meets the requirements of GOST R

52350.0-2005 for electrical apparatus of Group II that are exposed to a strong risk for mechanically inflicted damage. The surface areas of the LCD display and the IR interface are limited to

prevent the buildup of static electricity.

Integration of electrical ports into the flameproof enclosure complies with the requirements of GOST R 52350.0 und GOST R 52350.1.

The construction of the HV BL conforms to the general requirements of GOST R 52350.0-2005 for electrical equipment designed to be operated in explosion-hazard areas. The seals and connectors used for structural elements provide an IP 66 level of protection in accordance with GOST

14254.

All applicable explosion protection information is displayed on the housing of the Hygrovision BL as required by regulation.

2. SAFE OPERATION OF THE HYGROVISION BL

Place the analyzer on a level surface or mount it on the tripod near the extraction site. Take care that the bearing surface provides sufficient support for the analyzer.

Attach the gas delivery system (VYMP6.450.001; Pos.1, ILLUSTRATION 40) to the inlet port of the analyzer’s measuring chamber. Confirm that the high-pressure valve is closed.

Next, attach the gas flow and gas pressure control system (VYMP5.183.001; Pos. 3, ILLUSTRATION 40) to the outlet port of the measuring chamber (Pos. 2). Confirm that the fine adjustment valve of the gas flow / gas pressure control system is closed.

=11>?@34@=AB& & 9:&

Both of these systems use quick-connect couplers to attach to the analyzer’s inlet and outlet ports in order to not only reduce the time required for (de)installation but also to ensure an airtight seal at each of these points.

The analyzer connects to the gas supply by means of a flexible high-pressure hose equipped with a fine adjustment valve (Pos.2). Connect the end of the hose to outlet port of the extraction system’s shut-off valve. (Dk-Lok connector with an outer diameter of ø 6mm).

Gas that has passed through the measuring chamber is vented through a PVC hose (included with delivery) that is connected to the outlet nozzle (Pos.5) of the gas flow / gas pressure control system.

The gas flow can be altered as desired by means of the fine adjustment control valve on the gas flow / gas pressure control system. The manufacturer recommends an optimal volume flow of 0.5 – 1.0 Nl/min.

If the gas composition includes a large number of early-condensing hydrocarbons that interfere with the clear visual detection of the formation of water condensation, the user should install the supplemental filter for the control of heavy hydrocarbons (KRAY6.451.017; included with delivery).

This filter should be mounted between the high-pressure hose and the gas delivery system (VYMP6.450.001).

Attention!

When (de)installing pressurized devices in the sample gas extraction system or the gas preparation system (SGA), it is necessary to reduce the operating pressure to atmospheric pressure.

TESTING SEAL INTEGRITY

After the analyzer has been installed it is necessary to check that integrity of the sample delivery system connections using the following procedure:

1. Close the valve on the gas flow / pressure control system;

2. Slowly open the sample extraction system shutoff valve

and the valve at the inlet port of the analyzer’s measuring chamber;

3. Apply a soapy emulsion to the points of connection be-

tween the gas delivery system, the measuring chamber, and the gas flow and pressure control system, including between the locknut and connecting sleeve at each joint.

4. If bubbles are seen forming in the soapy emulsion it is a

sign that the corresponding connection is not properly sealed. The connection seal must be reseated to ensure air tightness.

Attention!

In situations where the dew point of inflammable gases is being measured, it is necessary to ventilate the analyzer’s measuring chamber and the sample gas delivery lines for 10 to 20 minutes before connecting the device to the power supply.

3.3. FUNCTIONAL TEST

When carrying out a functional test, use the following procedures (as described in detail below):

1. Switch on the analyzer;

2. Check the microscope lighting;

3. Check the condition of the condensation mirror;

4. Confirm that the thermoelectric battery is working properly;

5. Check that the date and time are correct;

SWITCHING ON THE

ANALYZER

=11>?@34@=AB& & 9C&

Press the red button on the left side of the analyzer to switch the device on (ILLUSTRATION 41).

The operating program (OP) requires one or two seconds to load. When the program has completed the startup sequence, the touch screen will display the last operating mode to which the device was set (ILLUSTRATION 26; ILLUSTRATION 27; ILLUSTRATION 33; ILLUSTRATION 34).

When the analyzer is switched on, the temperature of the condensation mirror (T) should largely correspond to the temperature of the housing (Tb), with a maximum deviation of ≈ ± 0.5°C.

CHECKING THE MICROSCOPE

Confirm that the microscope lighting is operating properly by tapping the “microscope lighting” icon (Pos.8, ILLUSTRATION 26;

LIGHTING

ILLUSTRATION 27). Look through the microscope to visually confirm that the lighting switches on and off.

Make sure that the microscope is optimally adjusted for viewing the surface of the condensation mirror.

Use the focusing ring to adjustment the sharpness of the image.

CHECKING THE

CONDENSATION MIRROR AND

THE THERMOELECTRIC BATTERY

Activate the “Transducer Cleaning Mode” as described in Point 4.2. It should only take a few minutes for the condensation mirror to heat up to a “cleaning” temperature of about +50 °C ± 0.1 °C.

If there are no problems during this process, it can be assumed that the thermoelectric element is functioning properly.

Check that the signal levels for UHC und UW are within tolerance.

If the system message “The mirror is dirty” is displayed, carry out technical maintenance as described in Point 5.2.

4. OPERATING THE HYGROVISION BL

4.1. PRECAUTIONARY MEASURES

The analyzer may be operated in both indoor and outdoor explosion hazard areas in accordance with GOST R 52350.14-2006 and other normative documents that regulate the use of electrical devices in explosion hazard areas.

Only fully qualified personnel are to install and operate this device. Further, this device may only be used by persons who are completely familiar with the guidelines and normative documents pertaining to working in explosion hazard areas. It is therefore strongly recommended that the relevant personnel receive instruction and training from Vympel GmbH.

During installation of the analyzer it is essential to avoid any friction or shocks that could generate sparks.

Before the analyzer may be (de)installed the shut-off valve on the sample extraction system and the shutoff valve on the gas delivery system must both be in the closed position and the pressure within the analyzer’s measurement chamber must be reduced to the ambient atmospheric pressure.

4.2. HANDLING THE HYGROVISION BL

PREPARING TO TAKE MEASUREMENTS

Before taking any measurements, please make sure that the analyzer and its accessory parts are all in proper working order.

When preparing the Hygrovision BL for operation:

• Affix the analyzer to a tripod or place it on a level surface;

• Carefully mount the microscope and plug ends of the micro-

scope lighting cord into the appropriate sockets;

• Connect additional accessories (computer terminal, pressure

transmitter, etc.) to the analyzer at the appropriate points;

• Before switching on the analyzer make sure that all of the

components are mounted in accordance with the requirements of Point 2.2;

• Carry out a functional test of the analyzer immediately before

beginning to take measurements. Also check the power source as described in point 1.8 of this manual.

HEATING THE

CONDENSATION MIRROR

=11>?@34@=AB& & 96&

Always clean the mirror before taking measurements by activating the “Transducer cleaning mode”.

Tap the icon to activate this mode (Pos.6; ILLUSTRATION 26; ILLUSTRATION 27).

When the icon is tapped the “Transducer cleaning mode” menu window is opened. The information displayed in this mode includes values for the mirror temperature (T), the signal levels for hydrocarbons (UHC) and water (UW), and signal level rejection criteria, as well as a text message confirming that the mirror is either clean or “dirty”. The process of heating the mirror to 50 °C is depicted as a changing value for T (,--./0120,34! ! $").

CLEANING THE MIRROR

If the message “The mirror is dirty” is displayed after the “Transducer cleaning mode” cycle is complete (,--./0120,34! ! $#), it will be necessary to clean the condensation mirror according to the instructions found under Point 5.2.

=11>?@34@=AB& & 9M&

When the desired measurement pressure has been reached, ensure that the microscope and the microscope lighting are adjusted to provide optimal viewing of the surface of the condensation mirror.

Adjust the sharpness of the mirror’s image using the focus ring on the microscope (Pos.3 ,--./0120,34! ! *$)

ADJUSTING THE LIGHTING

INTENSITY

When working out-of-doors it may be desirable to adjust the intensity of the condensation mirror illumination in response to various environmental factors and personal preference.

When taking dew point measurements, the process of condensation can be directly observed visually by means of the microscope (,--./0120,34! ! *; ,--./0120,3 4! ! ") alternatively, condensation can be monitored on the display by means of the optical-electric registration system (measurement scale – Pos.5, ,--./0120,3 4 ! ! "&5!

,--./0120,34! ! "'7

MIRROR SCAN /

SCANNING MODE

=11>?@34@=AB& & 99&

Scanning serves to simplify the process of registering the dew point manually. In scanning mode, the analyzer establishes an approximate dew point range within which lies the actually dew point.

Tap the function icon (Pos.7; ILLUSTRATION 26; ILLUSTRATION 27) to begin the scanning process. In this mode the condensation mirror is cooled at a rate of 0.5 °C per second until reaching a temperature at which a condensation film of water or hydrocarbons begins to form. When this point is reached the mirror is automatically reheated to a temperature exactly 10 °C above that at which the formation of condensation was initially registered.

The signal strengths corresponding to water and/or hydrocarbons condensation are displayed in the UW and U

menu windows.

In the “Level of fixation” window a value limit for the signal strength of the UHC and UW channels is displayed. When one of these values is exceeded the temperature of the mirror will stabilize at the corresponding level. The analyzer will determine whether the condensate is made of water or hydrocarbons based on which value is exceeded.

When the scanning process is completed, the letters HC will be displayed if the analyzer registers hydrocarbon condensation whereas the letter W will be shown for water condensation.

To end the scanning process, tap the icon (ILLUSTRATION

44). The analyzer will then be set to standby mode and the mirror will be maintained at the approximation temperature established in scanning mode (condensation temperature +10 °C).

At this point, select the desired dew point measurement mode by tapping the corresponding icon (Pos.10, ILLUSTRATION 26; ILLUSTRATION 27) to begin the DP measurement process.

TAKING DEW POINT

MEASUREMENTS

The Hygrovision BL is designed to provide two methods of dew point registration:

• Manually controlled dew point registration

• Automatic dew point registration

There are four options for manually controlled dew point registration:

• Hydrocarbon dew point measurement while cooling and

heating the condensation mirror at a preprogrammed rate

• Hydrocarbon dew point measurement while cooling the con-

densation mirror step by step

• Water dew point measurement while cooling and heating the

condensation mirror at a preprogrammed rate

• Water dew point measurement while cooling the condensa-

tion mirror step by step

There are two options for automatic dew point registration:

• Automatic measurement of the hydrocarbon dew point

• Automatic measurement of the water dew point

Dew point results registered in automatic mode are saved in the analyzers non-volatile memory and can be displayed at any time.

The Hygrovision BL is equipped with an IR-Port and an RS 485 interface for data transfer purposes. The corresponding computer software (Appendix K) is also included in delivery.

Attention!

When taking measurements for the dew point of water, if a significant amount of early-condensing hydrocarbons are observed (the formation of non-water drop like condensation), it will be absolutely necessary to install the filter (KRAY6.451.017) used for the control of heavy hydrocarbons.

4.3. HC DEW POINT MEASUREMENT USING

THE PREPROGRAMMED RATE OF COOLING / HEATING THE CONDENSATION MIRROR

1. Select the hydrocarbon measurement channel by activating the

icon (Pos.11, ILLUSTRATION 45). Set the analyzer to the

preprogrammed rate of cooling / heating (per ISO) mode by choos-

ing the icon (Pos.10). Tap the icon to activate the microscope lighting (Pos.8).

2. Push the “down” button (Pos.14, ILLUSTRATION 46) to begin cooling the condensation mirror at the preprogrammed rate (the factory default setting is 1 °C per minute).

3. As soon as a visually observable film of condensation begins to form, fix the temperature of the condensation mirror by once again pushing the “down” button (Pos.14, ILLUSTRATION 46). This fixed temperature value is shown in the Tc field of the display and the mirror temperature is maintained at this level.

4. Now push the “up” button (Pos.13, ILLUSTRATION 46) to begin heating the mirror at the preprogrammed rate. As soon as the condensate is observed to begin evaporating push the “up” button again to fix this temperature. This second fixed temperature value is shown in the Te field of the display.

In the case of hydrocarbons, the Tc value is, in fact, equivalent to the

Te value. In other words, condensation temperature and evaporation

temperature are the same for hydrocarbons. The fixed Tc and Te values may not diverge by more than 0.2 °C.

5. The measured dew point temperature is now shown in the DP field of the display and is stored in the analyzer’s memory.

6. To complete the measurement cycle, tap the icon (Pos.6, ILLUSTRATION 45) to switch the analyzer to mirror cleaning mode. At this point the condensation mirror will automatically be heated to 50 °C and the signal level will be reset to the starting value.

Pleas note: Should concurrent condensation of water vapor impair the observation of hydrocarbon condensation, the laser diode can be switched off by tapping the

icon.

4.7. HC DEW POINT MEASUREMENT IN

AUTOMATIC MODE

=11>?@34@=AB& & R:&

Tap the icon to set the analyzer to automatic mode for haydrocarbons. Refer to point 1.8.

When measuring the hydrocarbon dew point in automatic mode the following information will be shown on the left side of the display (see ILLUSTRATION 50):

• Current measurement mode HC;

• HC signal level;

• Current temperature of the condensation mirror T;

• Current temperature of the housing Tb;

• Icon for activating the microscope lighting

Measurement of the HC dew point is done by slowly cooling the condensation mirror at a preprogrammed rate (the factory default setting is 1 °C/min.) until the temperature is reached at which hydrocarbons begin to form a condensation film.

The measurement results are listed in a table that shows the following information:

• Time of the measurement;

• Dew point value in °C;

• Pressure in bar (when a pressure analyzer is con-

nected)

To erase the analyzer’s memory (measurement values shown in the table) push the “up” button (Pos. 13, ILLUSTRATION 46) and confirm your selection when prompted.

To change the parameters of the automatic measurement mode for hydrocarbons go to the “Settings: automatic mode” menu (Appendix I).

Please note: Adjustments to the analyzer’s sensitivity when measuring the hydrocarbon dew point can be made in the “HC- calibration” mode (refer to Appendix M).

Attention!

Values for the dew point of water that are registered in the HC mode are approximations and should only be used for purposes of general orientation. For accurate WDP values switch to the automatic mode for measuring the dew point of water.

4.8. WATER DEW POINT MEASUREMENT

IN AUTOMATIC MODE

=11>?@34@=AB& & RC&

Tap the icon to set the analyzer to automatic mode for Water. Refer to point 1.8.

When measuring the water dew point in automatic mode the following information will be shown on the left side of the display (ILLUSTRATION 51):

• Current measurement mode W;

• Signal level Uw;

• Current temperature of the condensation mirror Т;

• Current temperature of the housing Tb;

• Icon for activating the microscope lighting

In this mode the microscope lighting should be turned off for visual observation of the condensation process.

The measurement results are listed in a table that shows the following information:

• Time of the measurement;

• Dew point value in °C;

• Pressure in bar (when a pressure analyzer is con-

nected)

To erase the analyzer’s memory (measurement values shown in the table) push the “up” button (Pos. 13, ILLUSTRATION 46) and confirm your selection when prompted.

If the message “<” is shown in the DP field it means that the dew point could not be registered during the current measurement cycle. In this situation the lowest temperature to which the condensation mirror was cooled is entered in the table.

If this message is shown on your analyzer’s display, you should attach the supplemental cooling module and repeat the measurement process.

Water dew point measurement is done by means of slowly cooling the temperature-controllable condensation mirror (the faculty default setting is 1 °C/min.) At the point that condensation begins to form on the mirror’s surface, the current temperature is fixed as the Tc value. Next the mirror’s surface is slowly heated to the point at which the condensation begins to evaporate. This is fixed as the Te value. The dew point is the average of these two values.

To change the parameters of the automatic measurement mode for hydrocarbons go to the “Settings: automatic mode” menu (Appendix I).

4.9. SPECIAL CONSIDERATIONS WHEN

MEASURING DEW POINT AT VERY LOW TEMPERATURES

MEASURING DEW POINT AT

VERY LOW TEMPERATURES

The diagram in ILLUSTRATION 52 shows the effectiveness of the integrated cooling system with regard to controlling the temperature of the condensation mirror under a range of operating conditions.

The graph illustrates that the cooling system’s achievable results are directly dependent on the operating pressure as well as the housing temperature, which in turn is dependent on the ambient temperature.

Please note that the mirror cooling process can lead to an increase in the housing temperature. This increase can result in a housing temperature that is 5 °C – 7 °C above the ambient temperature.

As a result it may occasionally be necessary to subject the housing to supplemental cooling for individual measurements (-50°C).

The housing can be cooled using a variety of refrigerant media such as water, propane, natural gas, etc.

The analyzer housing has a cooling channel that provides for the smooth circulation of liquid and gaseous media under a maximum pressure of 100 bar.

The inlet and outlet connections for the housing cooling channel are fitted with cylindrical G1/8 male threading.

Alternatively, the supplemental cooling system can be used when taking dew point measurements at extremely low temperatures and very high working pressures. For information about the construction and function of this system refer to Point 1.6.

=11>?@34@=AB& & R6

Please note: The analyzer’s housing temperature (T

housing

/ Tb) must remain at least 5 °C above the dew point being measured for the entire period of any supplemental cooling.

SUPPLEMENTAL COOLING

SYSTEM

=11>?@34@=AB& & RM&

The vortex tube-based supplemental cooling system (VMPL5.880.003) is available as an optional accessory module See ILLUSTRATION 53.

The system is employed to cool the condensation mirror for measurements below -20 °C and under working pressure of more than 70 bar by means of the sample gas. For mounting and connection information refer to Appendix E.

The maximum allowable gas pressure at the entrance of the vortex tube is 17 bar. For this reason, the sample gas passes through a pressure regulator before reaching the vortex tube.

The recommended regulator output pressure is 7 – 9 bar (factory default setting).

INSTALLATION OF THE

SUPPLEMENTAL COOLING SYSTEM

Observe the following procedure when installing the supplemental cooling system:

1. Mount all of the cooling system’s components as illustrated in Appendix E:

2. Install the inlet fitting (Pos.12, Appendix E) into the ventilation channel for supplemental cooling;

3. Install the outlet fitting (Pos.19, Appendix E) into the ventilation channel for supplemental cooling;

4. Connect the input of the gas delivery system to the supplemental cooling system by means of a T- junction (Pos. 8)

5. The T- junction is attached to the inlet fitting of the analyzer-gas delivery system (Pos. 12) by means of a quickconnect coupler.

6. Connect the outlet of the cooling system to the ventilation channel inlet fitting (Pos.18).

7. The sample gas is discharged from the end of the vortex tube through a vinyl hose (Pos. 1). The sample gas flow rate is adjusted by means of the pressure regulator.

The gas-flow volume passing through the vortex tube should be:

• 45L/min for cold gas;

• 32L/min for hot gas.

USING THE SUPPLEMENTAL

COOLING SYSTEM

Use the following procedure to take dew point measurements when the supplemental cooling system is attached to the analyzer:

1. Connect the analyzer/supplemental cooling system assembly to the gas delivery system.

2. Initiate the flow of sample gas into the measurement chamber. Allow the gas to flow through the chamber for about five minutes at a volume flow rate of around 1L/min.

3. Switch on the analyzer.

4. Should the dew point lie beyond the range of the analyzer’s integrated cooling system, it is necessary to also supply sample gas to the supplemental cooling system. To do this, open the valve at Pos. 11, Appendix E.

5. Use the microscope to visually monitor the condition of the mirror’s surface. Determine at what temperature the condensation process begins, then, after the analyzer goes through a mirror cleaning cycle, take a dew point measurement.

6. Once dew point measurement is completed, close the valves controlling the gas flow and switch off the analyzer.

4.10. UNINSTALLING THE HYGROVISION BL

UNINSTALLING THE ANALYZER

Use the following procedure when uninstalling the analyzer:

1. Switch off the analyzer;

2. Close the high pressure valve on the gas delivery system (Pos. 2, ILLUSTRATION 16)

3. Use the fine control valve integrated into the flow control system (Pos.1, ILLUSTRATION 15) to adjust the pressure within the measurement chamber until it is reduced to coincide with the ambient atmospheric pressure.

4. Disconnect the flexible high-pressure hose from the analyzer (the hose connected to the sample extraction device.

5. TECHNICAL MAINTENANCE

5.1. GENERAL INSTRUCTIONS

In general, maintenance of the device consists of regular metrological recalibration, checking of the technical condition of the analyzer, and when appropriate, cleaning the mirror in accordance with Point 5.2.

Any repair that requires the opening of the analyzer’s seals must be carried out by the manufacturer or the manufacturer’s authorized agent.

5.2. MAINTENANCE PROCEDURES

Maintenance operations should include:

• Maintenance of the power supply unit (rechargeable battery pack);

• Inspection of the condition of the mirror and, when necessary, cleaning of the mirror;

• Checking the mirror cooling efficiency (the efficiency of the thermoelectric battery);

• Analyzer calibration;

• Visual inspection of the analyzer;

• Troubleshooting

MAINTENANCE OF THE POWER SUPPLY UNIT

Please observe the following guidelines to maximize the service life of the rechargeable battery pack:

• Continually monitor the charge status of the battery pack and recharge it when necessary;

• The charge status of the battery pack should be checked both during the preparation for taking dew point measurements as well as during the measurement procedure itself. For complete information refer to Point 3.3;

• When installing the battery pack, screw down the lid (Pos.3; ILLUSTRATION 11) that covers the battery pack slot until it is fully seated. Use the locking device (Pos.15; ILLUSTRATION 11) to secure the lid in place;

• If the analyzer is to be out of service for a period exceeding ten days, please remove the battery pack to avoid undesired battery discharge;

• All battery packs in storage should be checked once a month with regard to their charge status and when necessary fully recharged.

CLEANING THE

CONDENSATION MIRROR

Inspection of the condensation mirror’s surface is carried out in “Transducer cleaning mode”.

=11>?@34@=AB& & R9&

In “Transducer cleaning mode” the following elements are displayed on the touch screen:

• Temperature of the condensation mirror Т;

• Signal levels UHC and Uw (digital);

• Rejection criteria (maximum acceptable signal levels)

If the UHC und UW signal levels do not exceed the maximum acceptable values, it is not absolutely necessary to clean the condensation mirror.

If, after the “Transducer cleaning mode” cycle has complete, contaminants remain on the mirror’s surface, and these contaminants interfere with the visual observation and determination of the presence of water or hydrocarbon condensation on the mirror’s surface, please take the following steps before cleaning the mirror manually:

• Close the fine control valve (Pos. 2; ILLUSTRATION 16) on the gas delivery system;

• Adjust the pressure in the gas delivery system and the analyzer’s measurement chamber to the level of the ambient atmospheric pressure. Track changes in the pressure conditions by monitoring the flow control system’s manometer (Pos.1; ILLUSTRATION 15);

• Select the mode for water dew point measurement cool- ing the mirror step by step (see point 4.6);

• Set the target temperature (displayed in the field) to a value of -25 °C to -30 °C by repeatedly pressing the down button (Pos.14; ILLUSTRATION 46);

• When the target temperature has been reached, select the “Transducer cleaning mode”;

• Repeat this procedure up to three times if necessary;

If there is no improvement after several repetitions, it will be necessary to clean the condensation mirror manually.

All of the necessary items required for this procedure are included in delivery.

Please note: To increase the effectiveness of the sensor cleaning cycle, the manufacturer recommends the regularly purging of the analyzer’s measurement chamber using air or oxygen.

Attention!

Manual cleaning of the condensation mirror is ONLY to be carried out in an explosion safe environment!

CLEANING THE CONDENSATION

MIRROR

=11>?@34@=AB& & RR&

Use the following procedure when cleaning the condensation mirror manually:

• Switch off the analyzer;

• Close the fine control valve of the gas delivery system

(Pos.2; ILLUSTRATION 16);

• Disconnect the analyzer from the gas supply line and take it to an explosion-safe area;

• Disconnect the lighting system cord and remove the microscope by unscrewing it from its mounting;

• Cover the eyepiece of the microscope with the specially designed cap;

• Now, loosen and remove the eight bolts that secure the measurement chamber. The measurement chamber may only be opened in a sterile environment;

• Switch on the analyzer and start the Transducer clean- ing mode (as described above);

• Using a cotton swab dipped in cleaning fluid, cleanse the surface of the condensation mirror (ILLUSTRATION

55) employing very little to no pressure at all.

=11>?@34@=AB& & RT&

=11>?@34@=AB& & R;&

In some situations it is possible to carry out a “quick cleaning” of the condensation mirror.

Using the special key provided (VMPL 8.392001), unscrew the insert that houses the measurement chamber observation window and remove it (ILLUSTRATION 56). Once the insert is removed the surface of the condensation mirror is accessible and can be cleaned as described above (ILLUSTRATION 57).

Attention!

Extreme care should be taken when cleaning the mirror manually. Possible damage in the form of scratches or scoring greatly reduces the efficiency of the analyzer. Mechanical damage to the condensation mirror is not covered under warranty.

=11>?@34@=AB& & R8&

After cleaning has been completed, if the signal values for U

and Uw are once again within the normal range the message “The mirror is clean” will be displayed on the touch screen.

Reassemble the analyzer components following the above steps in reverse order.

Definitions for rejection criteria are initially set by the manufacturer (factory default settings). Changes to these values can be made under “Settings: Cleaning transducer” (see Appendix I).

Attention!

The rejection criteria are intended as recommendations from the manufacturer. These values serve to alert the operator that an excessive amount of contamination has accumulated on the surface of the condensation mirror and it should be inspected. If this contamination does not interfere with the measurement process, cleaning the mirror is not absolutely necessary.

TESTING THE THERMOELECTRIC

BATTERY (TEB)

The efficiency of the thermoelectric battery should be checked prior to calibrating the Hygrovision BL, as well as whenever the analyzer malfunctions (Pos.6; Table 4).

Use the following procedure to check the thermoelectric battery:

1. Select the step by step mode for taking dew point meas-

urements (Pos.10; ILLUSTRATION 49);

2. Press the down button (Pos.14; ILLUSTRATION 46) until the target temperature is reached: -60 °С;

3. After three minutes, fix the currently displayed mirror temperature T and the housing temperature Tb;

4. Start the Transducer cleaning mode by tapping

the icon;

5. At a housing temperature of 25 °C (± 5°C), the fixed mirror temperature T should not exceed -50 °C (± 5°C).

CALIBRATING FOR

HYDROCARBONS

The supplementary “Hydrocarbons calibration mode” makes it possible for the operator to fine tune the HC measurement channel when taking dew point measurements for hydrocarbons. For instructions on using this feature please refer to 299:;<=>!L.

Calibration of the analyzer is to be carried out in accordance with KRAY2.844.011MP.

The analyzer should be recalibrated about once a year.

21.1. UNIVERSAL TERMINAL PROGRAM: HYGROVISION.EXE

Application

The Hygrovision.exe terminal program serves two functions:

• To collect measurement data from the analyzer;

• To calibrate the analyzer.

System requirements

• IBM PC compatible: Intel Core i3 or newer

• OS: Windows XP / Windows 7

• RAM: minimum 2024MBs

• Hard drive: minimum 400 MBs free

• Display resolution: minimum 1366 x 768

• Mouse

Installing the terminal program

Copy the folder named “Hygrovision_4.5” from the CD (included with delivery) to the hard drive of your computer.

Configuring the data connection

Connect the Hygrovision BL analyzer to the COM port of your computer by means of the USB/RS 485 converter. Start the Hygrovision.exe program from the “bin” subfolder. After the program has loaded the following window will appear:

=11>?@34@=AB& & 8:&

Next, click on the “Connections” drop-down menu and select “Settings”. This opens the pop-up window shown in ILLUSTRATION 83.

Now select the COM port to which the analyzer is connected. Confirm that the Modbus address listed corresponds to the address set in the Analyzer (the factory default address is “100”). Click “OK” to confirm your connection settings.

=11>?@34@=AB& & 8C&

Once again click on the “Connection” drop down menu. This time select “Connect”.

If the correct COM port has been selected, a connection will be established between your computer terminal and the Hygrovision analyzer (see ILLUSTRATION 84).

=11>?@34@=AB& & 86&

The analyzer number is displayed in the upper right-hand corner of the window.

When a connection has been established, the field in the lower right-hand corner of the window will

have a green background .

If a connection has not been made successfully, the field in the lower right-hand corner will have a

red background . In this situation, check the COM port setting. (Refer to the text regarding ILLUSTRATION 83 above).

After the connection has been successfully established, dew point values will be listed in the table to the right in the main window and the sequence of temperatures registered during the measurement process will be plotted linearly on the scrolling graph.

The period of observation is listed in minutes. The interval can be adjusted by means of the “Period” filter (just to the right of the list of dew point values).

Use the “Record”, “Clear”, and “Copy” buttons to respectively save, delete, and copy the collected data.

To make adjustments to the graphical presentation, double click on the graph itself (using the left mouse button) to open a pop-up window. Select “Settings” to make changes to the values used for plotting the graph. Or select “Trends” to make changes to the appearance of the graph. (ILLUSTRATION 83)

=11>?@34@=AB& & 8M&

Accessing the calibration function

When the terminal program is started, the default access level is "0". This allows the user to store and display measurement data in both graphical and digital form, as well as track measurements for the purpose of analyzing the functionality of the device.

Should the user desire to calibrate the instrument, access level "1" is required.

Attention: Access to the calibration mode is protected by a password that is distributed on an individual basis as requested by the organization.

In order to change the level of access, click on the “Access” drop-down menu and select “Change”.

In the “Authorization” pop-up window that appears, select Level: 1 and enter the ten-digit password (ILLUSTRATION 84).

=11>?@34@=AB& & 89&

After entering a change to the authorization level, it is necessary to re-establish the analyzercomputer connection under the menu point “Connection”. Once the connection has been updated

(re-established) an additional menu point will appear labeled “Device” (see ILLUSTRATION 85). Various calibration protocols are accessible for alteration under this menu point. Newly entered values will be automatically entered in the calibration table.

Reading the analyzer’s current calibration values

To (re)calibrate the Hygrovision BL, enter the DP(W) value measured by a reference instrument in the column labeled “Calibrated”. The corresponding dew point value measured by the Hygrovision BL (that is being calibrated) is entered in the “Measured” column.

If the table does not exist or if it needs to be expanded to included more values, click on the “Add” button.

To delete individual values, click on the “Delete” button.

To save changes, after the calibration process has been completed select the “Device” drop-down menu and click on “Write”.

22. APPENDIX L

22.1. DESCRIPTION OF THE CALIBRATION PROCEDURE FOR

HYDROCARBONS

In order to increase accuracy, settings for the hydrocarbon measurement channel can be fine tuned in the Hydrocarbons calibration mode.

Calibration is carried out using a reference medium.

The hydrocarbon dew point is given by the generator (connected to the analyzer for purposes of calibration) or determined under operating conditions with the aid of a reference analyzer.

Connect the analyzer to a sampling device delivering gas that has a known dew point value.

Tap the icon (ILLUSTRATION 87) and select Hydrocarbons calibration mode.

=11>?@34@=AB& & 8;&

Enter the dew point value that was determined using the reference medium (or generator) in the “T” (temperature) field.

Next, tap the field labeled “Calibrate”.

This will switch the analyzer to HCdp mode. The dew point values measured now are determined based on the newly defined parameters and signal level values.

=11>?@34@=AB& & 88& &

Enter the dew point value that was determined using the reference medium (or generator) in the “T” (temperature) field.

Next, tap the field labeled “Calibrate”.

This will switch the analyzer to HCdp mode. The dew point values measured now are determined based on the newly defined parameters and signal level values.

After calibration is complete, tap the icon to switch to automatic HC dew point measurement mode. To reset the HC calibration parameter, open the menu “Settings; Parameters for the automatic mode; HC cycle” or, alternatively, recalibrate the analyzer using the Hydrocarbons calibration mode (as described here).

=11>?@34@=AB& & 8V& &

Individual calibration results are listed in the table on the analyzer’s display (T

given

±2 °C in 0.5 °C intervals).

The signal level that corresponds to the given HC dew point (in bold) will automatically be stored in the analyzer’s memory as the HC calibration parameter.

Until the first calibration is carried out, the calibration parameter “HC calibration” will be the same as the signal level for UHC.
