The Autobell®, a primary standard gas calibration system, is used to accurately measure a displaced volume of gas at a constant pressure. Interface electronics are provided to measure displaced volume and the time over which the volume is displaced so that a precise flow rate can be determined.
To calibrate a gas flow meter using the Autobell®, the flow meter must be installed upstream of the bell so that all gas flowing through it is captured by the calibrator.
QUICK SPECS
Primary standard gas calibration system
Flow range of 0.1 to 125 ACFM (2.83 to 3540 ALPM)
+/- 0.2% uncertainty of volumetric flow rate measurement (95% C.L.) typical
Interface using menu driven CalWare software
