General safety considerations

The process medium may be hot or otherwise hazardous. Use shields and protective clothing adequate for the process medium - do not rely on avoidance of contact with the process medium.

Manufacturer recommends to wear:

•long-sleeved safety clothing

•protective gloves

•safety glasses and/or goggles

•visor

•hard hat or helmet

•hard-cap safety boots

Precautions when removing a refractometer from the process line :

•Check first that the process line is depressurized and drained.

•Ensure you stay clear of any possible spillage and you have a clear emergency escape path.

•locate the nearest emergency shower and eye wash before starting work

1 Refractometer

Compact process refractometer PR-43-GC is designed for the general industry small pipelineandbypasslineapplications,e.g. inchemical,oil,gas,petrochemicalandkraft pulping process. Probe process refractrometer PR-43-GP is a general industry model that is typically installed in large pipes and vessels.

The PR-43-GC and PR-43-GP measure the refractive index nD and the temperature of the process medium. The concentration of the process liquid is calculated from these values when the composition of the process medium is known.

TheoutputvaluesoftherefractometeraretransmittedthroughmAoutputanddigitally throughanEthernetconnectionbyusingaUDP/IPprotocol(seethegeneralmanualfor specifications). mA output is available with mA output cable (mA only) or with a split cable (mA and Ethernet).

2 Mounting

The refractometer mounting location should be chosen with care to ensure reliable readings from the process.

2.1 Choosing the mounting location

Select a mounting location where sediments or gas bubbles cannot accumulate by the refractometer, such as in an outer corner of a pipe bend.

Important: Iftheprocesspipevibrates,supportthepipe. Avibratingpipemightdamage the in-line refractometer mounted on it.

AVaisalaK-PATENTS® inlinerefractometercanbelocatedeitherindoorsoroutdoorsin most climates. However, when a refractometer is located outdoors, some basic protection against direct exposure to sunlight and rain should be provided. Special care should be taken if the pipe wall is translucent (e.g. of fiberglass), as light from outside reaching the prism through the pipe wall may disturb the measurement.

Therefractometercovershouldnotbeexposedtohightemperatureradiation. Inmost cases, draft and natural convection provide sufficient air cooling if the air gets to flow freely around the refractometer head.

Additionalcoolingisnecessarywhentheambienttemperatureishigherthan45°C(113 °F)orwhentheprocesstemperatureisabove110°C(230°F)andtheambienttemperatureisabove35°C(95°F).Theaircoolingisimprovedbyblowingpressurizedairagainst therefractometercover. Thepressurizedaircanbesuppliedbytheventilationsystem. Another option is to install a water-cooled cooling cover PR-14038.

2.2 Electrical connections

The refractometer has an M12 connector in the refractometer for power supply, mA output and Ethernet connections.

PR-43 refractometers are powered with 24 VDC. For connecting the refractometer to Multichannel user interface MI, see the manual for Multichannel user interface. For connectingtherefractometertoCompactuserinterfaceCI,seethemanualforCompact

2.3 Insulation solutions

The process refractometer benefits from low ambient and high process temperatures with as little heat transfer as possible between the environment and the process. In good thermal conditions the hot prism surface is less susceptible to fouling, requiringlesswashingandsavingtherefractometerprism. Furthermore,insulationprevents heat transfer from the process to the electronics, ensuring error-free operation and longer lifetime for the electronics. Vaisala has developed custom-made removable insulation solutions for PR-43-GP.

2.3.1 Thermal insulator for PR-43-GP

The thermal insulator is installed in the manufacturing phase between the flange and the wash nozzle (if nozzle is present). If there is no wash nozzle, the thermal insulator canbeinstalledatanytime. ItismadeofPTFEandiswaterandchemicalresistant. The thermal insulator keeps the electronics in an optimal and stable temperature of under 65°C(150°F).Withthethermalinsulatorprocesstemperaturescanreachupto180°C (355 °F) without harming the refractometer electronics.

Table 2.1 Thermal insulator product models

Warning! If a PR-43-GP refractometer with insulator is installed in an explosive atmosphere, explosion hazard can be caused by an electrostatic charge generated in the insulator. In the presence of an explosive atmosphere, a PR-43-GP refractometer with thermal insulator shall only be used for measuring liquids with high conductivity (> 10000 pS/m).
