Autobell - Data Sheet

The New Generation 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 flowmeter using the Autobell ®, the flowmeter must be installed upstream of the bell so that all gas flowing through it is captured by the calibrator.
