12. g Jack Section 3 Theory of Operation 1 Primary Airflow Standard To be a primary standard all values must be absolute and measured as absolute A primary standard airflow measurement is a volume divided by a time interval as performed by the Control Unit of the Gilibrator The volume V is measured volume of space between two infrared sensors The time is that interval needed for a soap film bubble to traverse between the two sensors which bound the volume Therefore V t the volume per unit of time becomes the airflow and is prime because all measurements are basic volume and time In today s technology time is measured by an electronic clock whose accuracy exceeds that of volume measurements by orders of magnitude hence the control accuracy volume resides solely with volume measurements 2 Bubble Generation and measurement a The Gilibrator consists of two elements the Flow Cell Assembly and the Control Unit base The function of the Flow Cell Assembly is to generate a clean consistent bubble which traverses up the flow tube Meas urement of the traverse time is done by infrared sensor pairs which are mounted at the bottom and the top of the Sensor Block The volume bound by these sensors is specifically adjusted to a volume standard by allowing the upper sensor blocks to move in unison so as to enable this calibration to be set accurately to a primary volume standard A second function of the sensor block provides th
