Air sampling calibration
15 March 2018
Casella, the air sampling, noise and vibration monitoring specialist has introduced the Flow Detective air sampling pump calibrator.
The product is said to be the first in the industry with the ability to measure pulsation, with a 70-hour battery life.
Flow Detective allows 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. It is also said that the device will be the first on the market with a Bluetooth connectivity, through Casella’s Airwave App which Casella says is the only app of its kind providing 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 measures 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 Flow Detective calibrator saves significant time compared to other electronic or traditional bubble flow meter calibration methods minimizing set up prior to undertaking calibrations and enabling tagging pre and post calibration data. The device is also functional for both dust and vapour sampling from 25mL to 5L per minute. As it also measures temperature and pressure, this gives peace of mind that the units will always be accurate, regardless of the environment.
