Safety and warnings
The Flow Detective does not present a safety risk when you use it as instructed in this User
Manual. However, it is possible that the environment where you use the instrument may
present a safety risk. For this reason, always follow correct, safe working practices.
CAUTION
The Flow Detective is designed to be robust, however please use the unit as
follows:
•Do not drop the flow meter or subject it to mechanical shock.
•Avoid letting the flow meter suck in water, solid materials or corrosive gases
as this may cause damage and will invalidate the warranty.
•The Flow Detective contains no user serviceable parts. If a fault is suspected,
return the unit to Casella or a Casella approved service centre.
CAUTION
If the equipment is likely to come into contact with aggressive substances, take
precautions to prevent the instrument from being adversely affected, so that the
type of protection is not compromised. Aggressive substances such as solvents
may affect polymeric materials. Regular checks should be carried out to ensure no
damage has occurred.
CAUTION
Repair of this equipment shall only be carried out by the manufacturer or an
authorised representative in accordance with the applicable code of practice.
CAUTION
When Bluetooth® is enabled, care must be taken to avoid interference with
sensitive equipment such as in medical, aviation or safety critical environments.
Disposal
WEEE Notice
At the end of the instrument’s life please do not throw away with the
unsorted municipal waste. Please recycle with a registered WEEE
handler.

Introduction
The Flow Detective is the latest generation of digital
flow meter for the accurate calibration of personal
sampling pumps and other equivalent devices.
The Flow Detective is small and robust with no
moving parts and with the inbuilt Li ion battery the
unit will run for 70 hours between charges.
The Flow Detective has two separate models, the
Standard model is a flow meter for medium flow air
sampling pumps (0.5 –5L/min). This can be used to
calibrate pumps by noting the values from the
display accordingly. The Plus model has Bluetooth
connectivity to the Airwave App. After calibration,
the App will allow calibration data to be sent via
email for easy record keeping. When used to calibrate the Apex2 pump, this has the further
benefit that Airwave will control both the Apex2 and Flow Detective and automatically
calibrate to selected flow rates, making calibration very quick.
Flow Detective Plus models will also allow calibration at lower flows (20mL –0.5L/min) used
for gas and vapour sampling for sorbent tubes.
A unique feature of the Flow Detective is pulsation detection. This is important because in
ISO13137, the international standard for air sampling pumps, it stipulates that pulsation
must be below 10%. Pulsation is important for stable flow, especially when using cyclone
sampling heads to ensure an accurate size cut. The Flow Detective is the only flow meter on
the market to detect pulsation and display if levels are over 10%.
The following table summarises the features and capabilities of the Flow Detective models.

Controls and fittings
The Flow Detective has a limited number of easy to use controls which are summarised
below.
Controls and menu structure
Note: The air inlet is located on the back of the Flow Detective under the clip. Ensure the
inlet is not blocked.
The up / down arrows, which are used to scroll through menu and setting items
and also to change values.
The On / Off button, which is used to turn the flow meter on and off, and to
return to a previous screen.
The enter key, which is used to enter sub-menu items and to save changed
values.
This is the flow dashboard screen that displays after you turn on the
flow meter.
This is the menu that you use on a regular basis to change settings.

Protective boot
Ensure the protective boot (green in colour) is fitted at all times as it helps to guard against
knocks.
If you need to decontaminate the flow meter, remove the boot temporarily.
Note: The green rubber boot must not be fitted to intrinsically safe (I.S.) Apex2 units as this
will invalidate the I.S. certification of the Apex2.

Operation
This section describes how to use the flow meter using the minimum of settings. The Flow
Detective has many other menu and settings options and these are described in a later
chapter.
Turn the Flow Detective on/off
To turn on the Flow Detective:
On the top of the flow meter, press .
The following sequence is displayed. The second display shows the currently set time and
date as well as the firmware version. The battery charge state is then shown.
This is followed by the dashboard screen, showing instant and average flow. From this point
when air is run through the flowmeter it will display instantaneous and average flow as
shown on the dashboard screen below.
Press to switch between the flow display and the environmental display shown below:
To turn off the flow meter:
On the top of the flow meter, press and hold until the countdown has finished and the
screen goes blank.
Charge the Flow Detective battery
Before using the Flow Detective, check the battery level icon or battery gauge to ensure
there is enough charge for the intended measurements. The flow detective will run for 70
hours from a single charge so charging is not required on a regular basis. If the Flow
Flow Detective

Detective is not used for extended periods of time, such as several months, it is
recommended that the unit is still charged periodically.
To check the battery level:
1. Turn on the Flow Detective as described above.
2. Check the battery level, which will show as a percentage during the
start-up screens.
3. Turn off the Flow Detective as necessary.
The Flow Detective is supplied with a single charger station and power supply. A USB cable
for upgrading firmware of the unit is also supplied.
Note: A fully charged battery will last in excess of 70 hours of continuous operation.
To charge the flow meter battery:
1. Ensure that the Flow Detective is switched off.
2. Place the flowmeter on a charging station.
The red light on the top of the Flow Detective flashes during the
whole of the charging time and the charge state is displayed for a
user defined period.
3. To see the amount of charge at any time press .
Once fully charged the blue light turns on for 10 minutes, after which time the
flowmeter turns off.

Assemble the sample train
The sample train consists of the air sampling pump, air sampling head with a filter as well as
the necessary tubing. The pump should not be calibrated by itself, the sample train as a
whole is used to ensure the whole system is sound and leak free, including having the filter
already inserted in the sampling head. This all needs connecting to the flowmeter as shown
below.
Manual pump calibration
Manual pump calibration is to use the Flow Detective with a standard pump from any
manufacturer and uses the display of the Flow Detective to view the flow.
1. Switch the pump on and navigate the correct location for calibration on the pump –
see the instructions for the air sampling pump for more information.
2. Navigate to AVG TIME by pressing from the measurement screen, and then press
.
3. Press or to change the averaging time as desired, and then press . Press
to return to the flow display.
