Abstract

An automated gas measuring system comprises a constant pressure reactor system and a gas consumption monitoring system. A pressure drop in the reactor as a result of gas consumption is detected and the flow rate of gas to the reactor is adjusted to compensate for the pressure drop. Gas consumption is determined by measuring a drop in pressure in a gas holder due to the flow of gas from it to the constant pressure reactor system. The operations are controlled and automated by a control algorithm in a microcomputer.
