1. Description Aeroqual’s Dust Profiler is a user friendly instrument designed to provide continuous particulate

measurement of PM10, PM2.5, PM1, and TSP. It uses an optical particle counter to count and classify

particulate matter according to size. The instrument then converts the size distribution into a mass

measurement.

The instrument includes an embedded PC and two powerful software systems, Aeroqual Connect

and Aeroqual Cloud. There are numerous additional options available, including wireless

communications, SMS and email notifications, alarm functionality and the integration of factory tested

weather sensors. The instrument is packaged in a robust, lockable enclosure and is light enough for

one person site installations. The ease of installation, as well as the extensive range of possible add-

ons, enables the unit to be used in a wide range of applications.

Note: 12 VDC Power Supply mounted externally at base

The key components of the Dust Profiler are described below.

1.1 Optical Particle Counter

Aeroqual uses an OEM optical particle counter from Met One

Instruments. The particle counter uses scattered light to

measure and count particles. Light from a laser diode is

collimated to illuminate the aerosol sample flow. When a

particle is present it scatters the incident laser light which is

detected using a 60o solid angle elliptical mirror at right angles

to the laser beam. The amount of scattered light is converted

to a voltage pulse and the amplitude of the pulse is calibrated

to a particle diameter. The particles are thus assigned on the

basis of size to one of eight channels.

1.1.1 Electrical connections

The connections to the optical particle counter are at the bottom of the unit. There is also a LED which

turns red if there is a fault condition (see Troubleshooting section). The optical unit also requires an

earth wire to be connected between the housing and the 0VDC line on the power bus. Please check

that this is fitted if the unit has been replaced.

1.1.3. Inlet Heater

The Dust Profiler uses a 12 V heater on the sample inlet tube to reduce the humidity of sampled air to

prevent particle growth and fogging of the particle counter optics in high RH conditions. The inlet

should always be heated.

1.1.4. Inbuilt Filters

The Particle Counter engine requires two filters which are installed externally. They are designed to

provide protection to the pump and optical window. Both filters should be replaced at specified

intervals (See Maintenance Section 5). The BQ filter is the sheath air filter and the DQ filter is the

sample air filter.

Safety: This sensor is considered a Class I laser product. Class I laser products are not

considered to be hazardous. There are no user serviceable parts inside the cover of

the sensor. The device contains a laser operating at 670 nm which is visible to the eye

and can cause damage to the eye if directly exposed. Only trained service personnel

should attempt servicing or repair of the sensor.

MRK-D-0021 V1.0 Page | 7


1.1.2 Data Outputs

The Dust Profiler is configured to display and log particle mass by default. However, there is also an

option to configure the instrument to record particle counts. Refer to Section 4.5 for more information

on how to change the active sensors.

The pump and pneumatics are easy to access for servicing and replacement:

1.3. Power Module The Dust Profiler internal power requires regulated 12 VDC to

maintain a constant pump speed. An external mains to

12VDC power supply (Meanwell HLG80-12A 60W 12V) is

fitted on the outside of the enclosure and this will allow

connection to mains supply.

Note: If you wish to run the Dust Profiler on solar power

you will need to use a DC-DC convertor in order to supply a regulated 12 VDC for the Dust

Profiler

1.4. Auxiliary Module (Optional)

The auxiliary module acts as an interface between third party sensors and the Dust Profiler

communication bus. It is configured with different operating modes which can be selected by using

the dipswitches located on the side of the module. Aeroqual has integrated a number of third party

sensors and is able to supply the auxiliary module preconfigured for your sensors.

preconfigured for this sensor. Pin 2 (12V) and Pin 8 (4-20mA IN) need to be wired in.

1.5. Crevis PLC (Optional)

The Dust Profiler can be configured with a Crevis controller and

Crevis output cards. These output cards are designed to convert

the Dust Profiler’s digital values to analogue outputs. The cards

offer 4 x 4-20mA and 2 x relay outputs which can be user

configured in Aeroqual Connect or Aeroqual Cloud.

The Crevis controller type is Modbus NA-9171 and the mode type

is Modbus RTU. The outputs cards are ST-4214 for the 4-20mA

outputs and ST-2747 for the relay outputs. Further information

and specification on both these cards can be found on the USB

stick provided with the instrument.

The Crevis is powered by the Dust Profiler 12V power supply. As

a result the maximum load is 300ohms. If a higher maximum load

is required an external 24V power supply can be used to power

the Crevis. This will allow for a maximum load of at least

500ohms.

Wiring instructions can be found below. There are several glands

located at the base of the Dust Profiler which can be used to wire an external device.

3. Connecting to the Dust Profiler

3.1. Initial Connection using Aeroqual Connect

Aeroqual Connect is the standard user interface which comes with the Dust Profiler and allows the

user to be connected directly to the instrument. It can be accessed via WIFI, Ethernet or a cellular

modem. The on-board computer has an Ethernet output for direct wired connection. Alternatively,

connection can be made over WIFI by connecting to the Dust Profiler network (Access point mode), a

local network (Client mode) or via a modem.

The default setting of the instrument when first purchased will be to connect to Aeroqual Connect via

access point mode. Access point mode allows connection to the Dust Profiler via the Dust Profiler

network signal which will show up on a laptop, tablet or smart phone within range. This type of

connection will most commonly be used when working on the instrument in the field. However, it will

also be used to initially connect when the instrument first arrives.

Connecting by this mode will mean the user’s device is connected via WIFI directly to the Dust

Profiler. There will be no internet connection on the user device when using this option. To connect

you will need to select the Dust Profiler WIFI network and enter the password.

Note: The default user name and passwords can be found on Page 1 of the log book.

Once a WIFI connection has been made Aeroqual Connect can be accessed via the PC browser by

entering the IP address 10.10.0.1 in the address bar. The login screen below will then be displayed.

MRK-D-0021 V1.0 Page | 17


1. An Aeroqual Connect login name and password will be provided when Aeroqual Connect is

first purchased. If you do not know your login details please contact [email protected].

2. Once you have logged in the homepage will be displayed.

Note 1: Different applications will appear depending on the user accessibility configured for

your account.

Once the first connection has been made (via access point mode) the WIFI communications can be

configured according to how you would like the system to respond. This can be done via the settings

tab under the Configure Instrument application.

3.2. Connection Options

3.2.1. Client Mode

Client mode allows connection to the Dust Profiler via a local network (e.g. your office network). If

there is a local WIFI or LAN network available at the Dust Profiler installation site then the instrument

can be set up to connect to this network. This might be the case if the Dust Profiler is installed on the

perimeter of an industrial site and the WIFI network extends out to where the unit is installed.

Alternatively the Dust Profiler can be connected to the local network via an Ethernet cable from the

instrument to the local router using the Ethernet output on the base of the Dust Profiler.

When the Dust Profiler is connected to your local network (such as your office WIFI network), the local

network will automatically assign a local IP address to the instrument. The IP address assigned to the

instrument can be found in the Configure Instrument application when logged in via Aeroqual Cloud.

Entering this IP address into the web browser will open Aeroqual Connect for that specific instrument,

assuming you are within the local network.

If the local network allows outside access (e.g. via VPN), connection to the Dust Profiler can be made

from anywhere in the world. In the more common scenario where the local network does not permit

outside access you may still connect to the Dust Profiler using Aeroqual Cloud through the internet

because most local networks permit internet access.

To configure the Dust Profiler to use client mode the instrument needs to be configured via the

settings tab under the Configure Instrument application.

1. The WIFI mode needs to be set to Client

2. The WIFI SSID (local network name) needs to be entered (e.g. your office WIFI name)

3. The WIFI password needs to be entered (e.g. the password for your office WIFI)

Note 1: Before changing the WIFI settings it recommended that you have another connection

to the instrument established – typically by connecting the instrument to your LAN using the

Ethernet connection and using Connect with the LAN IP address.

Note 2: Once WIFI client mode is set up Aeroqual Connect will automatically disconnect from

WIFI access point mode. Connection will then need to be made via Aeroqual Cloud (See

section 4.5) to see the local IP address assigned to the instrument.

Note 3: If the local WIFI network password changes or you enter it incorrectly, you could be

locked out of the Dust Profiler. If this happens you will need to re-set the Dust Profiler back to

factory default settings, which puts the Dust Profiler back in to Access Point mode with a

default password. You can then reconfigure the settings correctly. Contact

[email protected] for information on how to perform this process.

MRK-D-0021 V1.0 Page | 18


3.2.2. Cellular Network Connection

If the Dust Profiler has an IP modem installed in the instrument a connection can be made via a

cellular network. This option is useful when remote access to the Dust Profiler is required but there is

no local network signal at the instrument installation site so client mode cannot be used. Aeroqual will

preconfigure the modem and load a default APN (Internet). This may work without having to be

changed. If set up is still required, only the APN, User name and Password needs to be modified.

Note1: A local data telecommunications contract and SIM card is required.

Note 2: The Dust Profiler uses approximately 20 megabytes per sensor per day. This is an

estimate for a Cloud connection and can vary wildly depending on the cellular provider.

Note 3: Using Aeroqual Connect via the modem will incur higher data usage.

1. The IP modem will need to be set up by plugging directly from the modem Ethernet port to a

laptop Ethernet port and browsing to 192.168.127.254.

2. In the menu select Network Settings GSM GPRS Settings and configure settings as per

picture below. Contact your SIM card provider to obtain full ATD and APN settings. Click

Submit button.

3. Unplug MOXA unit from the network and plug it into Dust Profiler embedded PC. Restart Dust

Profiler embedded PC and modem.

4. In the Configure Instrument application the Ethernet Mode setting needs to be set to Auto

(DHCP). WIFI mode should still be set to Access Point so a direct connection can still be

made.

5. If you do not wish to use Aeroqual Cloud, a DynDNS service will need to be set up to create a

permanent web address for the Dust Profiler.

6. A Dyn account can be created at https://account.dyn.com/cart/?via=upgrade-now

7. Log in to your account and add a new host name:

https://account.dyn.com/cart/?via=upgrade-now

MRK-D-0021 V1.0 Page | 19


8. Go back to MOXA modem configuration interface, and choose System Management - > Misc.

Network Settings - > DDNS. Select enable and DynDns.org. Input the host name created in

Dyn account, user name and password as well for the Dyn account. Then click Submit button,

Save and Restart. Now the modem should be ready to be connected via host name.

9. Enter the set up web address into the web browser to access Aeroqual Connect.

Note 1: No data is stored on the DynDNS server. It only acts as an access point to

communicate with the Dust Profiler.

Note 2: In some countries the telecommunications provider will block incoming requests to

the modem. If this is the case DynDns will not work with regular SIM cards. Contact your

telecommunications company about using an open APN or use a private APN.

3.3. Aeroqual Cloud When using Aeroqual Cloud, the user is connected to the Aeroqual Cloud server. The Dust Profiler

instrument is also connected to the Cloud server. The user connects to Cloud over the internet; the

Dust Profiler is connected to the Cloud server using WIFI, Ethernet or Cellular (modem required).

Aeroqual Cloud is a website.

Aeroqual Cloud allows management of either a single Dust Profiler unit or a network of Dust Profiler

units by using any internet-enabled browser.

As a user, you simply access Aeroqual cloud through the internet; Aeroqual Cloud is a website which

provides total control over your Dust Profiler. You will need to go to http://cloud.aeroqual.com and

enter your login name and password.

Note 1: If you do not know your login name and password please contact

[email protected]

As well as having access to all the features available in Aeroqual Connect, Aeroqual Cloud can be

used to manage a network of Dust Profilers. Depending on the user accessibility configured to your

account, Dust Profiler units can be managed by Organisations and Networks. This feature is available

in the Administration application.

The Dust Profiler must have internet access for you to see it and control it using the Cloud website.

For the Dust Profiler to have internet access it must be either in Client mode, as described above, and

be on a network which permits internet access (most networks do permit internet access). A modem

is not required in this situation.

Or if a local network is not available, the Dust Profiler must have an IP modem installed and a SIM

card and data contract with a local telecommunications provider.

System changes – Notifies when the Dust Profiler starts up, shuts down or is rebooted

Note 1: To manually create a journal entry select “Add user entry”, type in the relevant

information and press save.

Note 2: Service mode is initiated by starting “Manual Service Mode” in the Calibration and Service application. A journal entry will be automatically generated when the service is started and stopped.

4.2. Manage Data

The manage data application allows the user to view the data either as a chart or in a table. There is

the option to view the raw or averaged data as well as the ability to filter the data to show specific time

periods. The data can also be exported for further analysis within this application.

4.2.1. Charts

To view the data in graphical format select the “Charts” option.

The charts can be configured to view a specific time period using the “From” and “To” dates

shown at the top of the screen.

An averaging period can also be selected from the drop down menu

Note: The minimum average period is determined by the date range

MRK-D-0021 V1.0 Page | 23


4.2.2. Table

To view the data in a table select the “Table” option.

The data can be configured to view a specific time period using the “From” and “To” dates

shown at the top of the screen.

The data can also be filtered using the “Averaging Period” drop down menu to display:1

minute

Note 1: The minimum average period is determined by the date range

Note 2: Depending on the administration rights, raw data can also be viewed. This is 1 minute

data without data filtering in place

4.2.3. Download Data

Data can be downloaded by selecting “Download Data”.

A specific data set can be chosen for download by using the “From” and “To” date selection.

The Journal can also be downloaded if required.

Note: The data will be downloaded in csv. format

MRK-D-0021 V1.0 Page | 24


4.2.4. Manual Sync

If the Dust Profiler is outside of cellular and WIFI range, the Dust Profiler data can always be

downloaded to your device using a WIFI access point (see Section 3.1.) when at the instrument site.

The data will be downloaded to an unreadable file and will include all information stored on the Dust

Profiler on-board PC. The file can then be uploaded onto Aeroqual Cloud, once a WIFI or cellular

network is available, to view the data from the unit, including diagnostics and settings.

To download the data: In Aeroqual Connect select Manual Sync in the Manage Data application.

Here it will prompt you to select a location on your PC to download the data to.

To upload the data: In Aeroqual Cloud select Manual Sync in the Manage Data application. Here it

will prompt you to upload the file which was previously downloaded from Aeroqual Connect.

Note 1: If there is a lot of data to download from Aeroqual Connect multiple manual syncs may

need to be performed. The date in the manual sync function updates showing how much data

has been downloaded.

4.2.5. Auto Export (Optional Extra)

The auto export option allows the data to be automatically exported to either a selected email address

or to an FTP server. To set either of these features up they need to be enabled by selecting the

enable check box under the auto export option.

Email: To enable auto export to a specific email the frequency, format and averaging period needs to

be selected. There is also the option to include the journal in the export. Make sure a correct email

address is entered and save the changes for it to take effect.

FTP: To enable auto export to a FTP server the frequency, format and averaging period needs to be

selected. There is also the option to include the journal in the export. The FTP server, user name and

password also need to be entered correctly. Save the changes for it to take effect.

Note: The journal captures any error messages; these are particularly useful for

troubleshooting.

4.3. Calibration and Service The calibration and service application allows the user to perform manual adjustments to the gain and

offset settings for the particle counter.

4.3.1. Gain and Offset

Selecting the “Gain and Offset” menu will

display the gain and offsets for all the

configured PM sizes in the Dust Profiler.

Between 5 and 50 real time measurements will

also be displayed, as well as the average and

standard deviation for the shown readings.

These numbers will automatically update.

MRK-D-0021 V1.0 Page | 25


Prior to any manual calibration or servicing activities the “Manual Service Mode” button

should be started. This will ensure the raw data is highlighted and labelled appropriately to

show that a service is being performed. This is particularly helpful to alert when a calibration

has taken place to ensure the readings are disregarded from any future data analysis.

Note 1: Any flagged data is disregarded when calculating averaged readings.

Note 2: Remember to stop the “Manual Service Mode” after the service has been completed to

ensure future reported data is tagged as “Sample” data.

Note 3: The Manual Service Mode will automatically stop after 24 hours if left running.

The calibration parameters can be adjusted manually by clicking the setting that requires

changing, entering the new value and pressing save.

4.4. Diagnostics and Advanced The diagnostics and advanced application allows the user to view the sensor module settings as well

as the sensor diagnostics. This information is useful when fault diagnosing an issue with a module.

The diagnostic data can be exported for further analysis and the sensor module settings can be

updated or modified in this application.

4.4.1. Diagnostics

The diagnostics view will display the diagnostics for the selected parameter. The data can be

paused or exported using the buttons above the table.

40 minutes of data will be displayed at a time and the data will automatically update unless

the pause button is pressed.

4.4.2. Module Settings

The module settings view will show the individual module settings and version number for all the

parameters configured inside the Dust Profiler.

The module settings can be changed by selecting the value that needs changing, entering the

location or customer that is running the Dust Profiler

The device, software version and time last contact was made with the cloud

server is listed here for reference.

The time zone of the Dust Profiler can be set here to display the correct date for

the region the instrument is installed in.

The default averaging period can be configured here. Data can be configured to

read from 1 minute to daily averages.

Service time out can be set here. This is important if the manual service mode is

left on by accident. The time out value will stop manual service mode after the

time period set.

The restart instrument checkbox will force a restart of the embedded PC. The

checkbox will be cleared automatically after restart.

4.5.3. Configuring the Sensors

The default unit of measurement for PM is µg/m3.

The poll interval and poll time out functions will control how often the embedded

PC polls the modules. This should not be changed.

The active sensors will be displayed here. If a module has been added the

sensor will need to be selected from the drop down menu and added to the active

sensors list. Sensors can also be removed by clicking on the sensor name.

4.5.4. Configuring the PLC Output

If a Crevis is installed in the Dust Profiler the 4-20mA output module and relay

output module options should be check marked.

The baud rate and COM port used will also be shown here. These settings

should not be changed.

Note 1: For information on the communications section please see Section 3.

Note 2: For information on the legacy section please contact Aeroqual.

4.5.5. PLC Output

The 4-20mA and relay output modules can be configured here. There are four 4-20mA output

channels available which can be set to read a user defined parameter and range. The relay output

module has two relay options that can also be user configured. The paramenter, set point and reset

point can be added here. The relays can be configured as either rising or falling edge triggers.

If the set point is exceeded the relay is activated. This can be used to activate a siren or strobe or

other peripheral devices. The relay remains activated until the measured value drops below or

reaches above the reset point.

Rising Edge: Relay is energised when the concentration reaches above the set point and stays on

until the concentration drops below the reset point, which is set at a lower concentration than the set

point.

Falling Edge: Relay is energised when the concentration is below the set point and stays on until the

concentration reaches above the reset point, which is set at a higher concentration than the set point.

The relay will remain off until the concentration drops down below the set point.

MRK-D-0021 V1.0 Page | 28


Note: Please see Section 1.5 for more information on the Crevis PLC

4.5.6. Sensor List

The sensor list tab displays all the sensors that can be configured into the Dust Profiler. The table is

mainly for reference and shows all the settings configured for each sensor e.g. the units and

conversion factors. If a new sensor list is released it can be imported in this section.

4.5.7. Data filters

The negative number filter can be turned on for specific

parameters in this section. If you do not want the data to

show negative numbers for certain parameters, check the

checkbox of that specific parameter. Any negative

numbers reported will now show as zero.

Note: The negative number filter is NOT applied to

RAW readings. It is applied to all averaged readings.

MRK-D-0021 V1.0 Page | 29


4.5.8. Alerts (Optional Extra)

SMS and email alerts can be set up in this

section. Alerts can be set to notify when:

1. a concentration exceeds the user

defined set point

2. a sensor fails

3. the Dust Profiler is in operation mode

4. the Dust Profiler goes offline

Note 1: Operation mode allows alerts to be

sent when the mode changes. For example,

if the unit changes from normal mode to zero

calibration, or manual service mode an alert

is triggered. An alert will also be sent when

the unit returns to normal mode.

An email address and/or SMS number needs to be entered into the relevant fields to allow the alerts

to be sent. Multiple alerts can be set up by pressing the Add a new alert button.

Note 2: Phone numbers need to be in the format +64234566 with no spaces. A space is treated

as a separate phone number.

1.7.1.1.1.1.1. Note 2: All checks should be carried out during the initial commissioning of the Dust Profiler

5.2. Maintenance Procedures

5.2.1. Sample Flow Check and Adjustment

A constant 1.0 LPM flow is essential to ensure monitor is measuring correctly. To measure or set the

flow perform the procedure below:

1. Remove the TSP head from the inlet and connect a 0-2.5 LPM volumetric flow meter to the sample

inlet. Ensure the flow meter is on a steady surface and the correct flowmeter port is connected to the

Dust Profiler inlet.

2. Adjust the position of the Sample flow adjustment valve until the flowmeter reads 1.0 LPM.

Note: The inlet should be connected to the TOP of the volumetric flow meter (negative flow)

Afterwards replace the inlet components with care making sure there is no leak.

MRK-D-0021 V1.0 Page | 31


5.2.2. Sheath Flow Check

The sheath flow is a constant stream of air which ensures the optics remains clean. It is important this

is working correctly to maintain the accuracy of the measurement. To check the sheath flow:

1. Remove the TSP head from the inlet and connect a 0-2.5 LPM volumetric flow meter to the

sample inlet. Ensure the flow meter is on a steady surface and the correct flowmeter port is

connected to the Dust Profiler inlet.

2. Check that the sample flow is 1 LPM, if not adjust Sample flow valve (see above).

3. Pinch the purge tubing to block flow through the purge. This will increase the sample flow. If

the sample flow > 2.0 LPM then the sheath flow is good. If the sample flow < 2.0 LPM then

there is a problem. Change the filters and check for a leak.

5.2.3. Leak Check

If the correct sample or sheath flow cannot be achieved, there may be a leak in the pump module or

engine. First check the entire flow system:

Remove exhaust connection from the base of the enclosure

Remove the TSP head and block the PM inlet.

Connected the pressure end of a flow meter to the exhaust tubing.

If there is no leak the flow should drop to zero.

If the flow does not drop to zero it suggests there is a leak somewhere in the system. To check the

pump module:

Remove the sample connection and cap off the module sample port.

Connect the exhaust port of the module to the pressure end of a flow meter.

The flow should drop to zero.

If there is a leak in the pump module the module will need to be sent back to the Aeroqual factory.

Please contact technical support.

If there is no leak in the pump module it is likely the leak is located in the engine. In this case, the

engine will need to be sent back to the Aeroqual factory. Please contact technical support.

5.2.4. Manual Zero Air Check

A zero air check can be carried out manually. To do this the TSP inlet needs to be removed and the

particle filter (supplied with the instrument) needs to be attached to the monitor. Ensure there is a

good seal around the inlet.

The filter will remove 99.99% of particulates from ambient air. Wait 5 minutes and then check the

readings on the control module. The reported value should be <2 µg/m3.

MRK-D-0021 V1.0 Page | 32


5.2.5. Filter Changes

There are two green filters installed in the Dust Profiler. They are designed to provide

protection to the pump and optical window. The filters will become dirty and must be

replaced periodically.

To do this, unclip the filters from the connectors and replace. Ensure the filters are

connected the right way in accordance to the flow arrow. These filters can be

purchased from Aeroqual. Please contact technical support for a quotation.

Note: BQ filter – Sheath air filter

DQ filter – Sample air filter

5.2.6. Inlet Cleaning

The TSP inlet can be dismantled by unscrewing the 3 screws and separating the head into two parts.

Use a lint-free cloth wetted with isopropyl alcohol to clean both the inside and outside of the inlet.

Screws

MRK-D-0021 V1.0 Page | 33


6. Mass Calibration

All particle monitors based on light scattering require a site calibration for optimum accuracy. This is

because the average density and light scattering behaviour of dust particles will vary from site to site.

This adjustment is sometimes known as a “K-factor”. Aeroqual recommends a site calibration be

performed at the time of initial installation and then every 6-12 months. Calibration is performed by co-

locating the Dust Profiler with a Reference Particulate Matter measurement system and adjusting the

Gain of the particle monitor so the average reading matches that of the Reference Instrument. A list of

Reference instruments can be found at: http://www.epa.gov/ttnamti1/files/ambient/criteria/reference-

equivalent-methods-list.pdf

Install the Dust Profiler beside the Reference instrument. Make sure both instruments are setup

correctly. Two procedures are given below depending on whether the reference instrument is a

gravimetric or continuous instrument.

Procedure overview for Gravimetric Reference Instrument

1. Weigh a reference filter and install into the Reference instrument.

2. Leave the Dust Profiler and Reference instrument running for at least 24 hours until a weighable

quantity of particulate matter sample has been collected.

3. Check the sample flows of both instruments to ensure they are within specification.

4. Remove the Reference filter and re-weigh

5. Download the Dust Profiler PM data for the calibration period.

Calculations

1. Reference Filter Weight of PM (ug):

PM(Ref) = (filter weight at finish) – (filter weight at start)

2. Volume of air sampled by reference sampler (m3)

Volume(Ref) = minutes of test * Flow Ref (LPM) / 1000

3. Calculate average reference PM density (ug/m3)

AvPM(Ref) = PM(Ref)/ Volume(Ref)

4. Calculate average PM (ug/m3):

AvPM(Dust Profiler) = sum(PM readings over test period)/number of readings

Procedure overview for a Continuous Reference Instrument

1. Leave the Dust Profiler and Reference instrument running for at least 24 hours

2. Check the sample flows of both instruments to ensure they are within specification.

3. Download the Dust Profiler and Reference instrument data for the calibration period Calculations

1. Calculate average Dust Profiler PM (ug/m3):

AvPM(Dust Profiler) = sum(PM readings over test period)/number of readings

2. Calculate average Reference PM (ug/m3):

AvPM(Ref) = sum(PM readings over test period)/number of readings

Calculation of Dust Profiler Gain

1. Calculate K factor

K factor = AvPM(Ref) / AvPM(Dust Profiler)

2. You should then apply this to the Gain Factor on all the PM channels.

new GAIN = old GAIN x K Factor

11. Mounting and Site Positioning Guidelines

It is important that the positioning of the Dust Profiler is suitable so as to yield data which is

representative of that specific location.

1.1. Mounting The Dust Profiler comes with 2x mounting brackets and 3x U-bolts for 2 inch poles. The same

brackets are used for both pole and wall mounting. To wall mount the Dust Profiler the brackets are

screwed into the wall instead of using the U-bolts.

For pole mounting:

1. Secure top mounting bracket at a suitable height using 2x U-bolts provided

2. Fix lower mounting bracket to the Dust Profiler chassis with screws

3. Hang the Dust Profiler on the top mounting bracket

4. Place U-bolt through lower mounting bracket

Note: Only one U-bolt is used to secure the bottom bracket

5. Add nuts and washers and tighten the bottom U-bolt into position

1.2. Inlet height If PM monitoring is related to human exposure, the sampling inlet height should be positioned

in the “breathing zone”. This is located between 2 and 15 meters above ground level.

If PM monitoring is related to specific emission sources, the position of the sampling inlet can

be more flexible. It is more important that there is no obstruction between the approaching air

from the emission source and the sampling inlet.

If more than one Dust Profiler, or any other particulate instrument, is being used at the site,

the height of the inlets should be uniform.

If the Dust Profiler inlet is the highest point at the site, a lightning rod must be installed to

prevent damage to the unit during electrical storms.

4. 5.

MRK-D-0021 V1.0 Page | 42


1.3. Measurement Interference The meteorological conditions of the site should be taken into consideration when positioning

the Dust Profiler. For example, there should be no obstruction to the air flow in the

predominant wind direction. A minimum clear sky angle of 120 degrees is recommended.

The inlet should be at least 1 meter away from any objects that could potentially influence the

airflow characteristics e.g. trees, vertical surfaces or walls.

Avoid overhead high-voltage cables which may cause electrical interference with the

sampling equipment.

Demolition/construction activities and change to normal transport patterns due to road works

etc. can significantly affect the data. Ensure a record of such events is kept to account for

unexpected peaks in concentration.

1.4. Safety The intended data capture rate should be considered when positioning the Dust Profiler. If

data capture above 90% is essential, the unit should be located in an area which has 24 hour

access available.

The positioning should allow for routine maintenance checks to be performed safely by

personnel.

If using a tripod, ensure the tripod legs are bolted to the ground to prevent the unit from

falling. Ensure the Dust Profiler is in a secure location to avoid vandalism or theft.
