Air sampling pump calibrator

There are an estimated 18,000 new cases of breathing or lung problems a year caused or made worse by work, and an estimated 12,000 deaths from lung diseases linked to exposure at work. It is an employer’s duty to protect the health of employees through health surveillance and exposure monitoring. Air sampling is crucial and Casella’s latest Flow Detective is a robust solution allowing air sampling pumps to be calibrated, ensuring the pump has the correct flow, with traceable measurement results.

The Flow Detective is an electronic flow meter calibrator, designed to measure the flow of air sampling pumps to within 2% accuracy. The device has Bluetooth connectivity, through Casella’s Airwave App. Airwave provides remote control for dust and noise monitoring devices, enabling calibration results to be sent via email, ensuring improved traceability and pump calibration procedures. As well as detecting air flow, the Flow Detective can measure pulsation, indicating if the air flow pulsation exceeds 10%. Air sampling pumps must have a pulsation level less than 10% if they are to adhere to ISO 13137.  Excessive pulsation means an unsteady flow and has a detrimental effect on the ability of cyclone air samplers to collect the correct fraction of respirable dust.

The Flow Detective can be used with any manufacturers’ air sampling pumps. When used with Casella’s Apex2 personal dust sampling pump, the Apex2 and Flow Detective can be connected via the Airwave App allowing for closed loop airflow calibration with the ability to remotely set the flow via Airwave. This means no manual settings have to be done on the pump or flowmeter, drastically saving time when calibrating pumps.

The Flow Detective will save professionals additional time due to its simple user inter-face, colour-screen and wide flow measurement range, which can be used for all personal flow use with any pump. The device is functional for both dust and vapour sampling from 25mL to 5L per minute.
