Flow Detective

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.
