Cerulean - Model FPS-1 - Air Sampler Calibration Check Device Brochure

Cerulean Air Sampler Calibration Check Device is designed to check the calibration of Cerulean AS600 and AS600XR Air Samplers. At the heart of Cerulean Air Samplers is a flowmeter that uses a differential pressure orifice plate. As air flows through the orifice plate, it creates a pressure differential between the two faces of the  plate.  The difference in  pressure is dependant upon the flow rate and  thus accurate measurement of this pressure differential determines the flow rate. The pressure differential is detected by two pressure transducers located in the instrument box of the Cerulean Air Sampler.
