1 Refractometer
The sanitary refractometers PR-43-AC and PR-43-AP provide a digital interface detection system for alimentary industry. The PR-43-AC/AP (figure 1.1) measures 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. The output values of the refractometer are transmitted through mA output and digitally through an Ethernet connection by using a UDP/IP protocol (see the general manual for 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
The mounting location needs to be such that sediments or gas bubbles cannot accumulate by the refractometer. Good flow velocity is essential in keeping the prism clean. Important: If the process pipe vibrates, support the pipe. A vibrating pipe might damage the in-line refractometer mounted on it. A Vaisala K-PATENTS® inline refractometer can be located either indoors or outdoors in 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. The refractometer cover should not be exposed to high temperature radiation. In most cases, draft and natural convection provide sufficient air cooling if the air gets to flow freely around the refractometer head. Additional cooling is necessary when the ambient temperature is higher than 45 °C (113 °F) or when the process temperature is above 110 °C (230 °F) and the ambient temperature is above 35 °C (95 °F). The air cooling is improved by blowing pressurized air against the refractometer cover. The pressurized air can be supplied by the ventilation system. It is also possible to mount a PR-14038 cooling cover for cooling with water. Important: Always mount the refractometer so that the interconnecting cable points downwards from the refractometer head.
2.2 Check list for pipe mounting
The PR-43-AC and PR-43-AP are mounted in a pipe. Vaisala recommends a flow velocity between 1 and 3 m/s (3­10 ft/s). If the flow velocity exceeds 6 m/s (20 ft/s), there is a risk of cavitation. Cavitation may damage the refractometer and the piping. Too

slow a flow velocity may cause erraneous measurement readings due to coating of stratification (layering) of the sample on the prism. The diameter and form of the pipe and the process temperature all affect the measurement and need to be taken into account.
­ If the process pipe diameter varies, select the position with the smallest diameter (and accordingly highest velocity). Then the prism stays clean better.
­ If the refractometer is used in a feed-back control loop, make the time lag short. E.g. when a dilution valve is controlled, mount the refractometer close to the dilution point. However, make sure complete mixing has occurred at mounting location.
­ If the temperature varies along the process pipe, select the position with the highest process temperature. That minimizes the risk of coating, because higher temperature means higher solubility and also lower viscosity.
­ Often the position with the highest process pressure (= after pump + before valve) has favorable flow conditions without sedimentation or air trapping risks.
­ The refractometer should be conveniently accessible for service.
2.3 Check list for mounting in a tank, a vessel or a large pipe
A probe refractometer PR-43-AP can be inserted with a flange or clamp into tanks and vessels which either don't have a scraper or where the mixer doesn't touch the vessel wall. A probe refractometer can also be flush mounted in a cooker where the scraper touches the wall.
­ The inserted probe refractometer is mounted close to a stirrer to ensure representative sample of the process liquid and to keep the prism clean.
­ The refractometer should be conveniently accessible for service.

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

Figure 2.1 The M12 connector 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 connecting the refractometer to Compact user interface CI, see the manual for Compact user interface. See Figure 2.2 for instruction how to connect the M12 refractometer cable.
2.4.1 Wiring options The PR-43 refractometer provides both analogue (mA) and digital output signals. See Figure 2.3 for the wiring when only analogue output is used. Options for connecting the refractometer with both analogue and digital outputs are shown in Figure 2.4. Both Compact user interface CI and Multichannel user interface MI use the digital output signal.

PR-43-AC/AP instruction manual

3.3.5 PR-43-AC mounting specifics
Sanitary process refractometer PR-43-AC is connected to the process by a 2 1/2" 3A sanitary clamp. The recommended mounting is in a pipe bend, with a vertical flow upwards before the refractometer, and a horizontal pipe after. This mounting ensures
1. Self-cleaning of the prism due to the flow directed against its surface. 2. Efficient drainage when the pipe is emptied.
For pipe diameters of 3" or above, a ferrule is welded directly to the pipe wall, Figure 3.5 (a ferrule, length 21.5 mm, is delivered with standard refractometer delivery). For smaller pipe diameters, flow cells are available, Figures 3.6, 3.7, 3.8 and 3.9. The flow cells are exchangeable with standard 90° bend pieces.

PR-43-AC/AP instruction manual

3.3.6 Mounting specifics for EHEDG certified PR-43-AC configuration
Vaisala offers certain PR-43-AC configurations which have been certified to fulfill the sanitary requirements published by EHEDG (European Hygienic Engineering & Design Group) organization. During this certification the hygienic characteristics of both the refractometer and the process connection were evaluated against the applicable requirements. To ensure EHEDG compliant installation, follow the mounting specifics provided on the mounting drawing supplied by Vaisala with each PR-43-AC refractometer ordered with the -EH option. An example of such mounting guideline is shown in the Figure 3.12.
3.3.7 3-A Sanitary Standard compliance
The user should ensure that the refractometer is not a source of contamination to product due to damaged or worn product contact surfaces. Misuse (e.g. too long prism wash time or too high wash pressure) or mishandling may result in metal scratches or roughened surfaces. Such surfaces may not stay clean in processing. Vaisala offers a 3-A Sanitary Standard Accepted repair and maintenance package in which all wetted parts, prism, gaskets and dryer are replaced. Note that this repair service can be completed by 3-A authorized service center only.

3.4.5 PR-43-AP mounting specifics
The Probe refractometer PR-43-AP is primarily designed for mounting in a tank wall. To ensure that the measurement is representative and that the prism stays clean, the probe should be installed close to a stirrer.
Probe refractometer type PR-43-AP-H25 is connected to the process by a 2½ inch 3-A sanitary clamp.
Note: For higher process (or ambient) temperature, use instead a flush mounted refractometer, where the electronics in the refractometer head are farther away from the process heat.

PR-43-AC/AP instruction manual

4 Prism wash
Prism wash requires a system for wash control and diagnostics. This can be achieved with Multichannel user interface (MI) with a relay module.
4.1 Prism coating
Deposit build-up on the prism surface disturbs the measurement. An abnormally high concentration reading, an upward concentration (CONC) drift, decreased QF value or increased LED value may indicate coating. In most applications the prism will keep clean due to the self-cleaning effect. If coating occurs, check the following:
­ Sufficient flow velocity ­ A temperature difference between process fluid and refractometer probe may
cause coating. This may happen with small flows if the thermal insulation is inadequate. In some cases it helps to also insulate the clamp connector.
In case of a coating problem, the preferred solution is to try to increase the flow velocity, e.g. by installing a pipe portion with smaller diameter. Installing a wash nozzle can be considered, if increasing the velocity does not provide a solution (Section 4.2).
4.2 Prism wash
Three alternative wash media can be used for prism wash: steam, water, high pressure water. Relay modules in a Multichannel user interface MI can be configured to control the prism wash cycle, see MI manual, Chapter 6, "Module cards" and Chapter 7, "Prism wash". Important: In food industry applications, wash medium must be culinary steam or safe water. Shut-off valve and check valve must meet 3-A sanitary standards. Culinary steam: Shall mean steam produced using a system meeting criteria in the 3-A Accepted Practices for a Method of Producing Steam of a Culinary Quality, Number 609.

Safe Water: Shall mean water from a supply properly located, protected, and operated, and shall be of safe, sanitary quality. The water shall meet the standards prescribed in the National Primary Drinking Water Regulation of the Environmental Protection Agency (EPA) as referenced in The Code of Federal Regulations (CFR), Title 40, Parts 141, 142, and 143.

Important: In steam wash, do not exceed the recommended wash times, because some process media may burn to the prism surface if steamed for longer time. In case of coating, shorten the wash interval.
Note: In water wash, water temperature should be above the process temperature.
Note: The check valve pressure drop is 0.7 bar (10 psi).

4.2.2 Prism wash systems
The prism wash system for steam is described in Figure 4.1. The prism wash system for high pressure water is described by Figure 4.3.

5 Refractometer verification

Each Vaisala K-PATENTS® refractometer is provided with a calibration certificate comparing a set of standard liquids to the actual refractometer output. Therefore, the calibration and accuracy can be easily verified on-site with the certified refractive index liquids and menu guided verification procedure.
For verification you need:

­ Universal sample holder PR-1012 (see Figure 5.1 below). The sample holder keeps the sample on the prism surface and also keeps the ambient light out.
­ A set of standard refractive index liquids. ­ Cleaning solution (ethanol) to clean the refractometer prism and the sample holder.

The verification of the PR-43 refractometer calibration is made using a set of standard refractive index liquids with the nominal values at 25 °C:

­ 1.330 ­ 1.370 ­ 1.420 ­ 1.470 ­ 1.520

The accuracy of the certified standard refractive index liquids is ± 0.0002 and they can be traced back to national standards: NIST Standards # 1823 and # 1823 II. As the specified accuracy of PR-43 is ±0.0002, then the representative level is the sum of the two accuracy specifications, that is, ±0.0004.

Vaisala provides a set of standard R.I. liquids, PR2300, containing these five liquids. The set can be ordered directly from Vaisala or through your representative.

Figure 5.1 Universal sample holder PR-1012

A verification can be done by connecting to the refractometer over ethernet or by using a Multichannel user interface MI or Compact user interface CI. In web interface, choose Verification on the Main menu and follow the instructions on the page. In MI, tap the

PR-43-AC/AP instruction manual

three dots in the app for the refractometer to be verified, then choose Verification. Tap question mark in the Verification display to get verification instructions. In CI, choose Verification in the Main menu and follow the instructions on screen.
Important: For a successful verification, the refractometer and the standard refractive index liquids must be in room temperature (25 ±5 °C).
To check that the standard liquid is properly wetting the prism, the optical image can be monitored during the verification procedure. The optical image should show a sharp shadow edge.
The instrument measures each verification data point ten times and uses the average of these measurements. Measuring each verification liquid takes a few seconds, during which the measurement progress display is shown. Please wait until the verification step 2 display reappears before proceeding to next verification liquid. The limit for acceptance is that all measurements must be within ± 0.0004 of the nominal values.
If message is VERIFICATION FAILED, first check that the prism and the sample holder are absolutely clean and the sample holder sits tightly on the refractometer tip before a standard liquid is applied. Make sure the standard liquids are in good condition and not past their expiration date. Also, inspect the prism surface, checking that it is flat and glossy without any scratches. Repeat the verification procedure. If the verification still fails, fill in the PR-43 refractometer verification form, found at the end of this manual. The refractometer's serial number is shown in the upper right corner of each display. The list of CCD and TEMP values are found on the Verification results display. Send the form to your Vaisala K-PATENTS® representative or email the collected data to info@kpatents.com and wait for further instructions.
